Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
With the development of software services, the requirements of customers for services are changing, so that the version of an application program needs to be upgraded continuously. However, the application program of the upgraded version belongs to a newly developed program, and since the program is not verified for a long time, the program may be abnormal, which affects the normal operation of the software system. Therefore, in order to deal with the situation, emergency treatment needs to be performed without shutdown, and the application program is switched to an un-upgraded version, that is, a program which is verified for a long time and can be normally used, so that the normal operation of the software system is ensured.
At present, a common non-stop emergency disposal method includes that a configuration file or a database parameter is used to control program logic branch execution, so as to realize switching of application program versions. That is, the method requires that before the new version of the application is released, a parameter value, for example, a parameter name of switch, with a value of 1, is maintained in the configuration file or database to indicate that the new version logic branch is executed. When the new version of the application program has a problem, the value of the parameter name in the configuration file or the database is manually switched to 0, and at the moment, the old version logic branch is executed.
However, when the method is used for switching the application program versions, the corresponding configuration file or the corresponding database needs to be searched first and then the parameter values in the configuration file or the database need to be modified each time, so that the operation is inconvenient, and the application program versions cannot be switched in time. In addition, when the distributed scenario is addressed, parameter values in the configuration file or the database need to be modified for each server, which is time-consuming and labor-consuming.
The application program version switching method, device, equipment and system provided by the application aim to solve the technical problems in the prior art.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
The terms referred to in this application are explained first:
emergency disposal without shutdown: the method is characterized in that a client request is shunted to a logic branch of which the last version is verified to be error-free by modifying a configuration attribute value written in a program in advance. The attribute value configured in the program is usually written in the memory of the server, and the attribute value in the memory is usually immediately effective after being updated, so that the service can be quickly recovered and the loss is reduced by the quick non-stop processing mode.
Interface-oriented programming: it is meant that in a system, the various functions of the system are implemented by different interfaces. In the Java programming language specification, the interface is only responsible for defining each method, and the specific implementation logic of the method needs to be completed by an instance object (i.e. implementation class). When an external request comes, the actual logic processing and operation are also the instance objects. The specific implementation of each object module is completely transparent to the system, and the system does not need to know complex logic in the module and only concerns data and information feedback of the module.
Remote Dictionary service (Remote Dictionary Server, Redis): refers to an open-source memory-based key-value pair (key-value) storage system.
Example one
Fig. 1 is a flowchart of an application version switching method according to an embodiment of the present application, and as shown in fig. 1, the application version switching method according to the embodiment includes the following steps:
And 102, if a service request is received, controlling and executing the application programs of the corresponding versions according to the switch values currently stored in the remote dictionary service, wherein different switch values correspond to the application programs of different versions.
It should be noted that the execution main body of the application version switching method provided in this embodiment may be an application version switching device. In practical applications, the application version switching device may be implemented by a computer program, such as application software, a computer program, or a medium storing a related computer program, such as a usb disk, an optical disk, or the like; alternatively, it may be implemented by a physical device, such as a chip, etc., into which the relevant computer program is integrated or installed.
In this embodiment, in order to ensure that the software system operates normally, it is necessary to perform non-stop emergency treatment when necessary, that is, when an application program of a current version (that is, a new version) is abnormal, the application program of another version (that is, an old version) is timely switched to. Thus, to enable timely switching of application versions, the switch values currently stored in Redis may be modified. The switch value currently stored in the Redis may be a switch value read from a configuration file or a database.
It should be noted that, unlike the existing method of controlling the program logic branch execution by using the configuration file or the database parameter, the present embodiment controls the program logic branch execution by using the switch value stored in the Redis, so as to implement the switching of the application program version. Wherein, different switch values correspond to different program logic branches, i.e. different versions of application programs.
Further, the switch value stored in Redis may be managed by the switch value visualization management side page.
Specifically, after a user (i.e., a developer) inputs a switch value on a page of the switch value visual management end, the application version switching device may respond to the switch value input by the user and set the currently stored switch value in the Redis as the input switch value in real time. At this time, if the application version switching device receives a service request sent by a client, the application version switching device can control and execute the application of the corresponding version according to the currently stored switch value in the Redis, so that the application version can be switched in time.
Fig. 2 is a flowchart of an application version switching method according to an embodiment of the present application, where on the basis of the first embodiment, step 102 specifically includes the following steps:
In this embodiment, if an application version switching device receives a service request sent by a client, a service interface configured in advance is called, fig. 3 is a schematic diagram of the service interface provided in this embodiment of the present application, as shown in fig. 3, the service interface (i.e., interface a) is configured in an interface-oriented programming manner, a name of a method (i.e., a corresponding application service, such as a transfer function) is defined in interface a, and two implementation classes are included under the service interface and respectively correspond to an application of a new version and an old version, i.e., an old version implementation class B and a new version implementation class C.
The service request sent by the client is executed by the specific implementation class of the service interface, that is, the application version switching device can control and execute the application program of the version corresponding to the corresponding implementation class according to the switch value currently stored in the Redis. Wherein different switch values correspond to different implementation classes.
By the method, the application programs of different versions can be separated, the readability of the program is increased, the program maintenance is easy, if new application programs of different versions for switching are required to be added subsequently, only the implementation class D, the implementation class E, the implementation class F and the like are required to be newly established under the service interface, the implementation class D, the implementation class E, the implementation class F and the like correspond to the application programs of different versions respectively, and the corresponding application programs of the versions corresponding to the implementation classes are controlled to be executed by different switch values, so that the maintenance cost of the program is reduced.
In a possible implementation manner, on the basis of the first embodiment, the application version switching method is applied to a current master server under a remote dictionary service architecture, where the remote dictionary service architecture includes the master server and slave servers, and each slave server is deployed with the application version switching method.
In the embodiment, in order to solve the bottleneck problem of a single storage server in a traditional centralized storage system and improve the reliability, availability and expansibility of the system, an application program and data in a master server may be distributed over a plurality of slave servers through a network, that is, distributed. The Redis architecture is an architecture supporting distributed caching, and a master server is usually used for responding to a service request, so that the application version switching method provided by the embodiment of the application can be realized by the current master server under the Redis architecture, and the method is deployed in each slave server under the Redis architecture, so that the reliability of the system can be improved.
In addition, in an implementation manner, the switch value currently stored in the Redis of each slave server can be sent to the master server through a network, so that the application version switching device in the master server uniformly manages the switch values of the master server and the slave servers through the switch value visualization management end page, and thus, the switch value currently stored in the Redis of the master server and the slave server can be modified by one key, which is convenient and fast.
In the method for switching versions of an application program provided in this embodiment, in response to a switch value input by a user, a switch value currently stored in a remote dictionary service is set as the input switch value, and if a service request is received, an application program of a corresponding version is controlled to be executed according to the switch value currently stored in the remote dictionary service. That is to say, in the embodiment of the present application, the switch value is stored in the remote dictionary service, and the switch value is managed through the switch value visual management end page, when an emergency switching is performed, a user (i.e. a developer) can set the currently stored switch value in the remote dictionary service as the input switch value in real time only by inputting the switch value on the switch value visual management end page, and because different switch values correspond to different versions of the application program, at this time, if a service request is received, the application program of the corresponding version can be controlled and executed according to the currently stored switch value in the remote dictionary service, thereby implementing convenient and timely switching of application program versions.
Example two
On the basis of the first embodiment, in order to further explain the application version switching method of the present application, the method further includes: and updating the switch value currently stored in a database or a configuration file according to the switch value currently stored in the remote dictionary service.
Accordingly, the method further comprises: and if the switch value is not stored in the remote dictionary service currently, reading the switch value in a configuration file or a database and storing the switch value in the remote dictionary service.
In this embodiment, after the application version switching device sets the switch value currently stored in the Redis to the switch value input by the user, there may be a case where the switch value currently stored in the Redis is lost due to an instruction error or the like, and to cope with this case, the application version switching device may update the switch value currently stored in the database or the configuration file according to the switch value currently stored in the Redis for reading by the Redis.
Accordingly, if the switch value is not currently stored in the Redis, the application version switching device may read the switch value in the configuration file or the database and store the switch value in the Redis.
In an example, fig. 4 is a schematic flowchart of a switch value loading process provided in an embodiment of the present application, and as shown in fig. 4, when an application is initially started, a switch value is not currently stored in the Redis, at this time, the application version switching device may read the switch value in a configuration file or a database according to a setting, and store the read switch value in the Redis.
The scheme is suitable for Redis architectures including but not limited to a sentinel mode and a cluster mode. In combination with an actual scene, in a sentinel model, each Redis database can store the full amount of data, and the method is characterized in that data backup is complete and is suitable for an application scene with small data amount; the cluster mode cluster adopts distributed storage, each Redis instance stores different contents, and the keys are distributed to different Redis instances by calculating the hash value of the keys to be stored.
Combining the scheme with a cluster mode for example, the switching value loading process of the scheme mainly comprises the following steps: the cluster connection pool created by the springboot integration redis is used for expanding the Redis connection class in the original org.ff4j.redis library, StringRedistemperate generated by a springcontainer is directly used in the constructor of the cluster connection pool to assign to the local joddisCluster, and meanwhile, the getJedis () method is modified, and the joddisPool is not created any more and is directly returned to the joddisCluster. In addition, the configuration class FF4jConfiguration of the new definition FF4j adjusts the loading sequence through annotation configuration, so that the loading sequence is loaded after the redis cluster configuration is loaded, an FF4j instance is created in the configuration class, and the cache class featuretorredis instantiated by using the extended RedisConnection, thereby completing the loading of the switch value.
By the mode, the switch value can be stored in Redis, and a foundation is laid for realizing timely application program version switching in the follow-up process.
On the basis of the second embodiment, after reading the switch value in the configuration file or the database if the switch value is not currently stored in the remote dictionary service, the method further includes: if the switch value is not stored in the configuration file or the database, storing a preset default switch value in the remote dictionary service; the default switch value corresponds to a preset default version of the application program.
Correspondingly, in step 102, the controlling and executing the application program of the corresponding version according to the switch value currently stored in the remote dictionary service includes: and controlling to execute the application program of the default version according to the switch value currently stored in the remote dictionary service.
In this embodiment, if the switch value is not currently stored in the Redis, the application version switching device reads the switch value in the configuration file or the database in order to obtain the switch value, and at this time, if the switch value is not also stored in the configuration file or the database, the application version switching device stores a preset default switch value in the Redis. The default switch value corresponds to a preset default version of the application program. Accordingly, the application version switching means may control execution of the application of the default version according to the switch value currently stored in the Redis.
On the basis of any other implementation manner, in step 102, the controlling and executing the corresponding version of the application program according to the switch value currently stored in the remote dictionary service includes: if the switch value currently stored in the remote dictionary service is a first switch value, controlling to execute the application program of a first version; and if the switch value currently stored in the remote dictionary service is a second switch value, controlling to execute an application program of a second version, wherein the first switch value and the second switch value have different values, and the first version is different from the second version.
In this embodiment, if the switch value currently stored in the Redis is the first switch value, the application version switching device controls to execute the application of the first version. In practical applications, the first switch value may be true, the first version of the application program may be an upgraded version of the application program, and in a possible case, the application program corresponding to the class C may also be implemented for a new version under the service interface a. If the switch value currently stored in Redis is the second switch value, the application program version switching device controls to execute the application program of the second version. In practical applications, the second switch value may be false, the second version of the application program may be an un-upgraded version of the application program, and in a possible case, the application program corresponding to the class B may also be implemented for an old version under the service interface a.
The first switch value and the second switch value have different values, and the first version is different from the second version.
The default switch value may be the first switch value or the second switch value, and accordingly, the application program of the default version may be the application program of the first version or the application program of the second version.
Fig. 5 is a schematic flowchart of an application version switching process provided in an embodiment of the present application, and as shown in fig. 5, after an application version switching device receives a service request sent by a client, it may check whether a switch value is currently stored in a Redis, if the switch value is not currently stored in the Redis, read the switch value in a configuration file or a database and store the switch value in the Redis, if the switch value is not also configured in the configuration file or the database, store a preset default switch value (e.g., switch true) in the Redis, if the switch value is currently stored in the Redis, the application version switching device uses an Aspect Oriented Programming (AOP) dynamic proxy to invoke a preconfigured service interface, and if the switch value currently stored in the Redis is a first switch value (e.g., switch true), the application version switching device controls to execute an application corresponding to a new version implementation class C, if the switch value currently stored in the Redis is the second switch value (for example, the switch is false), the application version switching device controls to execute the application corresponding to the old version implementation class B, and returns the result after the application execution to the client, for example, returns the recharge result.
According to the method for switching the versions of the application programs, the application programs of different versions are controlled to be executed according to the switch value currently stored in the Redis, and the versions of the application programs are switched.

The setting module 51 is configured to set, in response to a switch value input by a user, a switch value currently stored in the remote dictionary service to the input switch value. And the control module 52 is configured to, if a service request is received, control execution of an application program of a corresponding version according to a switch value currently stored in the remote dictionary service, where different switch values correspond to application programs of different versions.
The application program version switching apparatus provided in this embodiment sets the switch value currently stored in the remote dictionary service as the input switch value in response to the switch value input by the user, and controls to execute the application program of the corresponding version according to the switch value currently stored in the remote dictionary service if the service request is received. That is to say, in the embodiment of the present application, the switch value is stored in the remote dictionary service, and the switch value is managed through the switch value visual management end page, when an emergency switching is performed, a user (i.e. a developer) can set the currently stored switch value in the remote dictionary service as the input switch value in real time only by inputting the switch value on the switch value visual management end page, and since different switch values correspond to different versions of the application program, at this time, if a service request is received, the application program of the corresponding version can be controlled and executed according to the currently stored switch value in the remote dictionary service, thereby implementing the application program version switching that is convenient to operate and timely.
In an optional implementation manner, the apparatus for switching application versions further includes: an update module 53 and a storage module 54.
