Detailed Description

Fig. 1 is a schematic diagram of a related art micro service system architecture. As shown in fig. 1, the micro service system 10 includes a service requester 11, a fuse 12, and a service provider 13, which are communicatively connected in order.

The service requester 11 is an initiator of a service request, and may be an entity physical device, or may be a certain entity part of the physical device, or may be a software function module of the physical device, for implementing a specific function. The service provider 13 is a responder to the service request for providing a service, and may provide a data processing service, a transaction processing service, or the like, for example. The fuse 12 and the service requester 11 may be located in the same physical device, so as to be different functional units of the physical device, or may be separately used as a physical device. The fuse 12 is configured with a fuse degradation policy. Before the service requester 11 initiates a service request to the service provider 13, a call request needs to be sent to the fuse 12, and the fuse 12 determines whether to allow the service requester 11 to send the service request to the service provider 13 according to a pre-configured fuse degradation policy.

As shown in fig. 1, in the micro service system 10, the fuse degradation policy is inserted into the service code of the service provider 11 by adopting a java hard coding mode, so that the invasiveness to the service code is high, and the expansibility is poor, i.e. the service code is not easy to change.

In view of this, the embodiment of the present application provides a micro service system, in which a configuration center server is set in the micro service system, all the fuse degradation policies of a plurality of micro services are stored in the configuration center server, and the degradation logic of the fuse degradation policies of the plurality of micro services is at least partially the same. The fuses acquire their corresponding fuse degradation policies by sending configuration requests to the configuration center server. In this case, the degradation logic is modified in the configuration center server, and a plurality of fuse degradation policies including the fuse degradation logic may be synchronously modified. In the related art, a hard coding mode is adopted to insert the fuse degradation policy into the service code, and even if a plurality of fuse degradation policies contain the same fuse degradation logic, the fuse degradation policies of each fuse need to be modified respectively. In comparison, the configuration method of the fuse in the micro-service system provided by the embodiment of the application is convenient for changing the fusing degradation policy code, and improves the expansibility of the fusing degradation policy code.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Fig. 2 is a schematic diagram of a micro service system according to an embodiment of the application. The micro service system 20 includes a configuration center server 21. The configuration center server 21 includes a configuration file, in which a plurality of fuse degradation policies are stored, and a corresponding relationship between each fuse degradation policy and an identity of the micro service. The fusing degradation policy may correspond to an identity of one micro-service, or may correspond to identities of multiple micro-services. The fuse degradation policies include fuse degradation logic, at least portions of which are identical for different fuse degradation policies, that is, the fuse degradation logic for different fuse degradation policies includes identical portions.

As shown in fig. 2, the micro-server system 20 further includes a micro-server 22, and the micro-server 22 is configured with a target micro-service 221 and a fuse 222, and the target micro-service 221 and the fuse 222 are communicatively connected. When the target micro service 221 is used as a service requester, the configuration center server 21 may send the fuse degradation policy corresponding to the target micro service 221 to the fuse 222 by executing the method for configuring fuses provided in the embodiment of the present application, so as to configure the fuse 222 with a fuse degradation function. In this case, the modification of the fuse degradation logic in the configuration center server 21 may synchronously modify a plurality of fuse degradation policies containing the fuse degradation logic. In the related art, a hard coding mode is adopted to insert the fusing degradation strategy into the service code, and the fusing degradation strategy of each fuse needs to be modified respectively. In comparison, the configuration method of the fuse in the micro-service system provided by the embodiment of the application is convenient for changing the fusing degradation policy code, and improves the expansibility of the fusing degradation policy code.

In one embodiment, the fuse 222 determines whether to allow the targeted micro-service 221 to initiate a service request to the service provider 23 based on the fuse degradation policy in combination with its state and statistics in that state. The states of the fuse 222 may include an open state, a closed state, and a half open state. The statistical information includes the response of the service provider 23 to the service request issued by the service requester 221. The response conditions referred to herein may include half-on timing, etc. The half-on timing refers to the time that the fuse 222 is in the half-on state, and the on timing refers to the time that the fuse 222 is in the on state.

The fuse degradation policy is, for example, when the target micro service 221 issues a service request to the fuse 222, if the fuse 222 is in a closed state, that is, a state where the resource of the service provider 23 can be invoked by the target micro service 221, the fuse 222 returns a result of passing the request to the target micro service 221. If the fuse 222 is in the half-open state, the fuse 222 determines whether to allow the service request based on whether the half-open time exceeds a first time threshold. Specifically, if the half-open timer does not exceed the first time threshold, the fuse 222 grants the service request at a first probability; if the half-on timer exceeds the first time threshold, the fuse 222 allows the service request. If the fuse 222 is in the on state, the fuse 222 determines whether to allow the service request based on whether the on timer exceeds a second time threshold. Specifically, if the on-time does not exceed the second time threshold, the fuse 222 allows the service request with a second probability; if the on-time exceeds the second time threshold, the fuse 222 allows the service request.

The first probability and the second probability mentioned above are the duty cycle of the normal response of the target micro service 221 to the service request issued by the service provider 23. The values of the first probability and the second probability can be equal or unequal, and the values are reasonably set according to actual conditions.

The statistics may also include a proportion of unresponsiveness to service requests, a proportion of timeout responses to service requests, an average response time, a count of normal responses to service requests, and so forth. In this case, the fuse 222 may also switch its state in accordance with the fuse degradation policy in combination with the statistical information. Accordingly, the fuse degradation policy further includes: and when the proportion of unresponsive service requests reaches a first threshold value, the proportion of overtime response to the service requests reaches a second threshold value, and the average response time to the service requests reaches a third threshold value in the first period, updating the state of the fuse from the closed state to the open state. When the on-time exceeds a third time threshold, the state of the fuse is updated from an on-state to a half-on-state when the count of normal responses to service requests reaches a first number threshold. When the count of normal responses to the service requests reaches a second number threshold, the state of the fuse is updated from a half-open state to a closed state.

In one embodiment, preset fuse degradation logic is also stored in the configuration file of the configuration center server 21. The fuse degradation policy stored in the configuration file may include an entirety of the preset fuse degradation logic, or may include a portion of the preset fuse degradation logic. In particular, the preset fuse degradation logic includes at least one fuse degradation sub-logic, each of which may be a separate module, and the fuse degradation policy may invoke all or part of the fuse degradation sub-logic of the preset fuse degradation logic.

The fuse degradation sub-logic includes at least one fuse degradation parameter. The fuse degradation parameters include statistical information, such as, for example, a fuse degradation policy in the micro-service system 10 shown in fig. 1, the fuse degradation parameters include a half-on timer, an on timer, a proportion of unresponsiveness to service requests, a proportion of timeout responses to service requests, an average response time, and a count of normal responses to service requests.

A user configuration interface is developed through the target micro-service 221 for configuring the values of the fuse degradation parameters and the target identity in the fuse degradation logic. The values of the configured fuse degradation parameters and the target identity are synchronized to the configuration center server 21. The configuration center server 21 acquires the value of the fuse degradation parameter and the target identity contained in the at least one fuse degradation sub-logic, generates a target fuse degradation policy based on the acquired value of the fuse degradation parameter and the target identity, and a correspondence between the target fuse degradation policy and the target identity. In this case, the developer of the target micro service 221 may use preset fuse degradation logic stored in the configuration center server 21 to obtain a target fuse degradation policy that meets its own needs through the values of the fuse degradation parameters configured at the user configuration interface. Thus, the user can directly utilize the preset fusing degradation logic stored in the configuration center server 21 without developing the preset fusing degradation logic, and the production cost is reduced. It should be appreciated that pre-written fuse degradation policies may also be stored in a configuration file without configuration using a user configuration interface.

As shown in fig. 2, the micro-server system 20 further includes a service provider 23, and the service provider 23 may be provided in another micro-server. The fuse 222 determines whether to allow the target micro-service 221 to issue a service request to the service requester 23 according to the configured fuse degradation policy.

The following describes in detail the execution process of the method for configuring the fuse in the micro service system according to the embodiment of the present application with reference to the accompanying drawings.

Fig. 3 is a flowchart of a method for configuring fuses in a micro service system according to a first embodiment of the present application. Referring to fig. 2, the configuration method 300 is performed by the configuration center server 21. As shown in fig. 3, the configuration method 300 includes:

In step S310, a configuration request of the fuse 222 is obtained, where the configuration request includes the target identity of the target micro service 221.

When the micro server 22 where the target micro service 221 is located is started up, the target micro service 221 sends a start signal to the fuse 222. After receiving the activation signal, the fuse 222 forms a configuration request based on the activation signal, where the configuration request includes an identity of the target micro-service 221, for example, a service name of the target micro-service 221.

Step S320, searching a target fusing degradation strategy corresponding to the target identity in the configuration file based on the target identity. That is, the fuse 222 transmits the configuration request to the configuration center server 21, and after the configuration center server 21 receives the configuration request, the fuse degradation policy of the target micro service 221 is searched from its configuration file.

In the present embodiment, the configuration file of the configuration center server 21 includes a plurality of fuse demotion policies, and the correspondence between each of the plurality of fuse demotion policies and the service name of the micro service. In this case, the configuration center server 21 performs traversal search on the configuration file according to the service name of the target micro service 221 included in the configuration request, so as to match the fuse degradation policy corresponding to the service name of the target micro service 221, that is, the target fuse degradation policy. The target fuse degradation policy may be a fuse degradation policy in the related art, for example, the fuse degradation policy mentioned in the micro service system 10 shown in fig. 1, which is not limited in this embodiment.

In step S330, when the target fuse degradation policy is found, the target fuse degradation policy is sent to the fuse 222 for fuse degradation function configuration of the fuse 222. The configured fuses 222 may determine whether to allow the target micro service 221 to issue a call request to the service provider according to the fuse degradation policy in combination with the state of the fuses 222 and statistical information in the recorded state thereof. The specific implementation of the fuse 222 refers to the description of the fuse 222 in the micro service system 10 shown in fig. 1, and will not be repeated here.

According to the method for configuring fuses provided in the present embodiment, by setting the configuration center server 21 in the micro service system 20, the fuse degradation policies of a plurality of micro services are all stored in the configuration center server 21, and the degradation logic of the fuse degradation policies of the plurality of micro services is at least partially the same. The fuse 222 obtains its corresponding fuse degradation policy by sending a configuration request to the configuration hub server 21. In this case, the modification of the fuse degradation logic in the configuration center server 21 may synchronously modify a plurality of fuse degradation policies containing the fuse degradation logic. In the prior art, the fusing degradation policy is inserted into the service code by hard coding, and needs to be modified for each fuse 222 separately. In comparison, the configuration method of the fuse 222 in the micro service system provided by the embodiment of the application is convenient for changing the fusing degradation policy code, and improves the expansibility of the fusing degradation policy code.

Fig. 4 is a flowchart illustrating a method for configuring fuses in a micro service system according to a second embodiment of the present application. The configuration method 400 shown in fig. 4 differs from the configuration method 300 shown in fig. 3 in that in this embodiment, the configuration file of the configuration center server 21 also stores a preset fuse degradation policy. The preset fuse degradation policy belongs to one of the fuse degradation policies, which is not set separately for a specific micro service, and may be sent to a fuse connected to the micro service when the fuse degradation policy is not stored in the configuration center server 21 by a developer of the micro service.

Specifically, the configuration method 400 further includes, based on the configuration method 300 shown in fig. 3:

in step S410, when the target fuse degradation policy is not found, the preset fuse degradation policy is sent to the fuse 222 for performing fuse degradation function configuration on the fuse 222.

Specifically, traversal search is performed in the configuration file based on the service name of the target micro service 221, and if a fuse degradation policy corresponding to the service name is found, the fuse degradation policy is determined as the target fuse degradation policy of the target micro service 221. If the fuse degradation policy corresponding to the service name is not found, determining the preset fuse degradation policy as the target fuse degradation policy of the target micro service 221. By setting the preset fuse degradation policy, it can be ensured that any one of the micro services in the micro service system 20 has a corresponding fuse degradation policy available, and that the whole micro service system is highly available.

Fig. 5 is a flowchart illustrating a method for configuring fuses in a micro service system according to a third embodiment of the present application. In this embodiment, the configuration file further includes preset fuse degradation logic including a plurality of fuse degradation sub-logics including at least one fuse degradation parameter. As shown in fig. 5, the configuration method 500 further includes, based on the configuration method (taking the configuration method 300 shown in fig. 3 as an example) provided in any one of the foregoing embodiments:

step S510, obtaining a value of a fuse degradation parameter and a target identity contained in at least one fuse degradation sub-logic.

The preset fuse degradation logic includes a fuse degradation parameter. The fuse degradation parameters include statistical information, such as, for example, a fuse degradation policy in the micro-service system 10 shown in fig. 1, the fuse degradation parameters include a half-on timer, an on timer, a proportion of unresponsiveness to service requests, a proportion of timeout responses to service requests, an average response time, and a count of normal responses to service requests. The value of the fuse degradation parameter and the fuse degradation logic together comprise a degradation policy. Configuration hub server 22 stores preset fuse degradation logic that includes a plurality of fuse degradation sub-logic. The target micro service provides a user configuration interface, and a user can select a fusing degradation sub-logic in the user configuration interface according to own requirements, set values of fusing degradation parameters contained in the selected fusing degradation sub-logic and a target identity, and then synchronize the configuration parameters to the configuration center server 21.

Step S520, a target fuse degradation strategy is generated based on the value of the fuse degradation parameter and the target identity, and a corresponding relation between the target fuse degradation strategy and the target identity is established. After the configuration central server 21 obtains the value of the fusing degradation parameter, a fusing degradation policy is formed based on the fusing degradation parameter, and a corresponding relation between the fusing degradation policy and the target identity is established, so that the target fusing degradation policy is obtained.

According to the method for configuring fuses provided in this embodiment, preset fuse degradation logic is stored in the configuration center server 21 in advance, and the preset fuse degradation logic includes a plurality of fuse degradation sub-logics, and each fuse degradation sub-logic is an independent module. The fusing degradation parameters contained in the fusing degradation sub-logic can be set or modified through a user configuration interface provided by the target micro-service 221 to obtain a fusing degradation strategy meeting the self requirements of the target micro-service 221, so that the privately customized fusing degradation strategy is realized, the operation process is simple, the implementation is easy, and the modification is convenient. At the same time, different micro-services 221 may share the same fuse downgrade sub-logic, that is, a set of fuse downgrade sub-logic may be stored in the configuration center server 21, which may be invoked by multiple fuse downgrade policies, reducing code redundancy compared to storing the same set of fuse downgrade sub-logic for each fuse downgrade policy.

The application also provides a configuration device of the fuse in the micro-service system, which can be used as a functional unit of the configuration center server for executing the steps of the configuration method provided by any embodiment. Fig. 6 is a block diagram of a configuration device 60 of a fuse according to a first embodiment of the present application. As shown in fig. 6, the configuration device 60 includes an acquisition module 61, a search module 62, and a transmission module 63. The obtaining module 61 is configured to obtain a configuration request of the fuse, where the configuration request includes a target identity of a target micro-service. The searching module 62 is configured to search the configuration file for a target fuse degradation policy corresponding to the target identity based on the target identity. The sending module 63 is configured to send the target fuse degradation policy to the fuse when the target fuse degradation policy is found, so as to configure the fuse with a fuse degradation function.

According to the configuration device of the fuse provided by the embodiment, the fuse degradation policies of a plurality of micro services are stored in the configuration center server, and the degradation logic of the fuse degradation policies of the plurality of micro services is at least partially identical. The fuses acquire their corresponding fuse degradation policies by sending configuration requests to the configuration center server. In this case, modifying the fuse degradation logic in the configuration hub server may synchronously modify a plurality of fuse degradation policies that contain the fuse degradation logic. In the prior art, a hard coding mode is adopted to insert the fusing degradation strategy into the service code, and the fusing degradation strategy of each fuse needs to be modified respectively. In comparison, the configuration method of the fuse in the micro-service system provided by the embodiment of the application is convenient for changing the fusing degradation policy code, and improves the expansibility of the fusing degradation policy code.

In one embodiment, the sending module 63 is further configured to send the preset fuse degradation policy to the fuse for performing fuse degradation function configuration on the fuse when the target fuse degradation policy is not found.

According to the configuration device of the fuse provided in this embodiment, it may be determined whether a target fuse degradation policy of the target micro service 221 exists in a configuration file of the configuration center server, if so, the target fuse degradation policy is sent to the fuse 222, and if not, a preset fuse degradation policy is sent to the fuse 222. In this way, it can be ensured that any one of the micro services in the micro service system 20 has a corresponding fuse degradation policy available, ensuring that the entire micro service system is highly available.

Fig. 7 is a block diagram of a configuration device of a fuse according to a second embodiment of the present application. As shown in fig. 7, the configuration file further includes preset fuse degradation logic including a plurality of fuse degradation sub-logics, each including at least one fuse degradation parameter. In this case, the obtaining module 61 is further configured to obtain the value of the fuse degradation parameter and the target identity, which are included in at least one fuse degradation sub-logic. Configuration device 70 further comprises a generation module 71 for generating the target fuse degradation policy based on the obtained value of the fuse degradation parameter, and a correspondence between the target fuse degradation policy and the target identity.

In one embodiment, the obtaining module 61 is specifically configured to obtain the value of the fuse degradation parameter and the target identity through a user configuration interface provided by the target micro service.

According to the configuration device of the fuse provided in this embodiment, the preset fuse degradation logic is pre-stored in the configuration center server 21, the preset fuse degradation logic includes at least one fuse degradation sub-logic, and the fuse degradation parameters included in the fuse degradation sub-logic can be set or modified through the user interface configuration interface provided by the target micro-service to obtain the fuse degradation policy meeting the self-requirement of the target micro-service 221, so that the privately customized fuse degradation policy is realized, the operation process is simple, the implementation is easy, and the modification is convenient. At the same time, different micro-services may share the same fuse degradation sub-logic, thereby reducing code redundancy.

The application also provides a fusing degradation method which is suitable for the micro-service system 20 shown in fig. 2. Fig. 8 is a flowchart of a fuse degradation method according to an embodiment of the present application. The fuse degradation method is performed by the fuse 22. As shown in fig. 8, the fuse degradation method 800 includes:

Step S810 (not shown in the figure) issues a configuration request to the configuration center server 21 based on the start signal of the target micro service 221.

After the micro server where the target micro service 221 is located is started, a start signal is sent to the fuse 222. Based on the activation signal, the fuse 222 forms a configuration request that includes an identification of the target micro-service 221, such as a service name of the target micro-service 221. The fuse 222 sends a configuration request to the configuration center server 22.

In step S820, the fuse degradation policy returned by the configuration center server 21 is received to perform the fuse degradation function configuration.

After receiving the configuration request sent by the fuse 222, the configuration center server 21 executes the steps of the method for configuring a fuse provided in any of the embodiments above, so as to send the fuse degradation policy of the target micro service 221 to the fuse 222. After receiving the fuse degradation policy, the fuse 222 loads the fuse degradation policy to implement the fuse degradation function configuration.

In step S830, in response to the call request issued by the target micro service 221, it is determined whether to allow the target micro service 221 to transmit a service request to the service provider 23 based on the self state of the fuse 222. If not, go to step S840 and step S850; if so, step S860 and step S860 are performed.

For example, in the present embodiment, the states of the fuse 222 include an off state and an on state. When the fuse 222 is in the off state, i.e., the service provider 23 is in the unavailable state, the fuse 222 returns the disallowed call information. When the fuse 222 is in an on state, i.e., the service provider 23 is in an available state, the fuse 222 returns permission-to-invoke information.

Step S840, returning a preset response result.

Specifically, when the fuse 222 is in the off state, i.e., the service provider 23 is in an unavailable state, the fusing callback function is triggered, and a preset response result is returned. The preset response result may be a history return result of the calling service provider 23 stored in the cache, or identification information for indicating that the service provider 23 is abnormal.

In step S850, it is determined whether to modify the state of the fuse 222 based on the statistical information recorded by the fuse 222.

For example, the statistics include a proportion of service requests not responded, a proportion of service request timeout responses, and an average response time to service requests. And when the proportion of unresponsive service requests reaches a first threshold value, the proportion of overtime response to the service requests reaches a second threshold value, and the average response time to the service requests reaches a third threshold value in the first period, updating the state of the fuse from the closed state to the open state.

In step S860, the service request of the target micro service 221 is forwarded to the service provider 23, and the response result of the service provider 23 to the service request is received.

The service request issued by the target micro service 221 reaches the fuse 222 through the gateway aggregation layer, and the fuse 222 forwards the service request to the service provider. Upon receiving the service request, the service provider 23 responds to the service request and returns the response result to the fuse 222.

In step S870, the response result is stored in the buffer of the fuse 222, so that when the service provider 23 is abnormal, the response result is returned to the target micro service 221 as the preset response result mentioned in step S840.

Returning to step S850. For example, the statistics also include a count of normal responses to the service request.
