Example 1
Fig. 1 is a flowchart of an annotation hot refreshing method provided in an embodiment of the present invention, where the embodiment is applicable to a case of hot refreshing @ @ configuration properties annotation in a high concurrence scenario, and the method may be performed by an annotation hot refreshing device, where the annotation hot refreshing device may be implemented in a form of hardware and/or software, and the annotation hot refreshing device may be configured in electronic devices such as a mobile phone, a computer, and a server.
In this embodiment, the @ configuration properties annotation is an annotation in the Spring framework for binding configuration items in configuration information to Bean classes of Java. The Spring framework is an open-source lightweight application framework and is used for constructing enterprise-level Java application programs. Bean classes are Java classes that are used to characterize data objects or business logic in Java applications. The Bean class includes a plurality of Bean class attributes, such as a scope of the Bean class (whether a single instance or a prototype), whether it is a primary Bean (primary) class, and description information.
As shown in fig. 1, the method includes:
s110, acquiring remote configuration information to obtain a configuration resource list.
In this embodiment, the remote configuration information is information stored by the server for updating the client configuration (e.g., network configuration, security configuration, and software configuration). The remote configuration information includes information of a plurality of configuration resources, wherein the configuration resources are various elements or parameters that the client needs to configure, such as environment variables, system variables, database connection information, API keys or access tokens of log configuration and third party services, and the like.
Specifically, the client sends a remote configuration information acquisition request to the server under the condition of triggering configuration acquisition operation. The remote configuration information acquisition request is a configuration information acquisition request based on a preset protocol (for example, HTTP protocol), and is used for establishing a connection between a client and a configuration acquisition service of a server. The configuration acquisition service is a service for acquiring remote configuration information and transmitting the remote configuration information to a client. The server side responds to the remote configuration information acquisition request, triggers the detection operation of the remote configuration information in the server side, starts the configuration acquisition service, and feeds back the remote configuration information acquisition request including the remote configuration information to the client side. The client analyzes the remote configuration information acquisition request response to obtain the remote configuration information.
The client generates a configuration item key list based on each piece of configuration information in the remote configuration information, wherein the configuration item key list takes a configuration resource attribute index as a list of elements, and the configuration resource attribute index is a unique identity of the configuration resource attribute. It will be appreciated that each configuration item key list corresponds to a Bean class annotated by @ configuration properties, each configuration item corresponds to a Bean class attribute in the Bean class, the configuration items exist in the form of key value pairs, the configuration item keys are configuration resource attribute indexes, the configuration item values are values of configuration resource attributes, for example, "database addresses" are configuration item keys, and "localhost" is a configuration item value.
The configuration item key list identifier is a unique identity identifier of the configuration item key list and is used for characterizing a unique configuration resource, for example, the configuration item key list identifier may be a name of the configuration resource such as a configuration file, a database table, a file path, a service endpoint, and the like. The client generates a configuration resource list based on all configuration item key lists corresponding to the remote configuration information, wherein the configuration resource list is a list taking the configuration item key list as an element and is used for managing and maintaining the configuration resource.
In some embodiments, the configuration acquisition operation is triggered based on a configuration update of the server. Optionally, sending a configuration state detection request to the server, so that the server returns a configuration state update response signal when detecting that the remote configuration information is updated; triggering a remote configuration information acquisition request based on the received configuration state updating response signal, and obtaining remote configuration information from a server based on the remote configuration information acquisition request; and/or triggering a remote configuration information acquisition request based on the preset interval time, and obtaining the remote configuration information from the server based on the remote configuration information acquisition request.
In this embodiment, the configuration state detection request is a request for detecting a server side configuration state, where the configuration state includes a configuration updated state and a configuration non-updated state.
Specifically, the client executes the configuration state detection task, generates a configuration state detection request, and sends the configuration state detection request to the server. And the server responds to the configuration state detection request and performs update detection of remote configuration information. In the event that a new configuration resource is detected, it is determined that there is an update in the remote configuration information and the server configuration state is a configuration update state, the configuration state detection service generates a configuration state update response signal (e.g., the configuration state update response signal is a high level signal) and feeds back the configuration state update response signal to the client that sent the configuration state detection request.
And after the configuration state detection service returns a configuration state update response signal to the client, the configuration state detection service is closed. Optionally, in response to the configuration state detection request, triggering the configuration state detection service to start, and scanning the configuration release information database based on a preset interval time; under the condition that new configuration release information exists in the configuration release information database, determining that remote configuration information is updated; and suspending the configuration state detection request within a preset waiting time under the condition that no new configuration release information exists in the configuration release information database.
In this embodiment, the configuration state detection service is a service in which the server detects the configuration state of the remote configuration information. The configuration release information database is a database in which configuration release information is stored. The configuration release information database is a database for storing configuration release information, wherein the configuration release information is information released by a development application terminal and comprises information of a plurality of configuration resources.
Specifically, the server receives the configuration release information through the configuration service management interface, and stores the configuration release information in the configuration release information database. Under the condition that a configuration state detection request is received, the server starts a configuration state detection service, the configuration state detection service records the starting time, and the detection operation of the configuration information is executed at regular time, so that the real-time performance of remote configuration information acquisition can be ensured.
And under the condition that the difference value between the current time and the starting time is smaller than or equal to the preset waiting time, the configuration state detection service scans the configuration release information database and traverses each configuration release information. Under the condition that new configuration release information is scanned, the remote configuration information can be considered to be updated, the configuration state of the server is determined to be a configuration update state, a configuration state update response signal is generated, and the configuration state detection service is closed; and under the condition that the new configuration release information is not scanned, the client suspends the configuration state detection request, so that the configuration state detection service scans the configuration release information database at intervals of preset scanning intervals until the client receives a configuration state update response signal. The preset scanning interval time is preset interval time of two adjacent scanning configuration release information database operations, and is 1 second in an exemplary mode.
And under the condition that the difference between the current time and the starting time is larger than the preset waiting time, the remote configuration information is considered to be not updated, the client stops suspending the configuration state detection request, and the configuration state detection service is closed.
In some embodiments, the configuration release information further includes a configuration information update notification. The configuration state detection service scans the configuration information update notification stored in the configuration release information database, and when the new configuration information update notification is scanned, the remote configuration information can be considered to be updated, and then the server configuration state is determined to be the configuration update state. The configuration state detection service determines the configuration state of the server based on the configuration information update notification instead of specific configuration information, and can timely detect that remote configuration information is updated, so that the configuration state update response signal is immediately fed back to the client.
The client triggers remote configuration information acquisition operation based on the received configuration state updating response signal, generates a remote configuration information acquisition request, and sends the remote configuration information acquisition request to the server. The server responds to the remote configuration information acquisition request, starts configuration acquisition service, and feeds back new remote configuration information to the client.
In some embodiments, optionally, the client triggers a state detection task based on the received configuration state update response signal, and sends the configuration state detection request to the server again.
The client side triggers remote configuration information acquisition operation at intervals of preset intervals. The preset interval time is interval time for generating remote configuration information acquisition requests twice. And triggering remote configuration information acquisition operation to generate a remote configuration information acquisition request under the condition that the difference between the current time and the generation time of the last remote configuration information acquisition request is larger than the preset interval time, and acquiring remote configuration information from a server based on the remote configuration information acquisition request. The preset interval is, for example, 5 minutes.
According to the technical scheme, based on the remote configuration information acquisition request, new remote configuration information is acquired from the server, and the remote configuration information acquisition operation can be triggered at intervals of preset intervals under the condition that the configuration state update response signal is not effective (for example, communication between the server and the client is interrupted, and the configuration state update response signal is missed), so that the reliability of the new remote configuration information acquisition is ensured.
S120, comparing the local configuration information corresponding to the configuration item key cache list with the remote configuration information, and storing the configuration item key of the last acquired remote configuration information in the configuration item key cache list.
In this embodiment, the configuration item key cache list is a list for caching configuration item keys in the client. The configuration item key cache list identifier is a unique identity identifier of each configuration item key cache list and is used for representing configuration resources corresponding to the configuration item key cache list. The local configuration information is the last remote configuration information corresponding to the plurality of configuration item key cache lists. Illustratively, the remote configuration information is acquired at a current time of 13:00:00, and the remote configuration information is acquired last time before the local configuration information is 13:00:00.
Specifically, each configuration item key list identifier of the configuration resource list is matched with the configuration item key cache list identifier. And under the condition that the corresponding configuration item key cache list identification is matched, the fact that the configuration item key cache list is matched with the configuration item key list can be determined, and then each configuration item key of the configuration item key list is matched with the configuration item key in the configuration item key cache list. In the event that each configuration item key of the list of configuration item keys matches a configuration item key in the cache list of configuration item keys, it may be determined that the local configuration information matches the remote configuration information.
And S130, triggering a configuration change monitor to start under the condition that the local configuration information is not matched with the remote configuration information, and updating the configuration item key cache list based on the remote configuration information, wherein the configuration change monitor is used for monitoring the configuration change of the configuration item key cache list.
In this embodiment, if the configuration item key list identifier of any configuration item key list in the configuration resource list is not matched with the configuration item key cache list identifier in the local configuration information; or any configuration item key in the configuration item key list is not matched with the configuration item key in the corresponding configuration item key cache list, and the fact that the local configuration information is not matched with the remote configuration information can be determined.
Specifically, the configuration change listener is a preset configuration properties refresh processor, and the configuration change listener is exemplified by one or more of HttpSessionAttributeListener, listener and servletrequest attributelistener, and the like. If the local configuration information does not match the remote configuration information, the configuration item key cache list is updated based on the remote configuration information, and configuration changes, such as addition, modification and deletion of configuration items, exist in the updated configuration item key cache list.
S140, when the configuration change monitor monitors the configuration change of the configuration item key cache list, an environment change event is issued; and responding to the release of the environment change event, and updating the annotation Bean attribute based on the updated configuration item key cache list so as to realize the annotation heat refreshing.
In this embodiment, the configuration information is a configuration item value corresponding to a configuration item key found in the configuration resource based on the configuration item key in the updated configuration item key cache list.
Specifically, the environment change event is an event that characterizes the Bean attribute to be updated. If the configuration change monitor monitors the configuration change of the configuration item key cache list, the Bean attribute can be considered to be required to be updated, and the client is triggered to issue an environment change event. Triggering @ configuration properties notes to rebind the configuration information corresponding to the updated configuration item key cache list and the Bean attribute under the condition that the configuration change monitor monitors the issued environment change event so as to realize annotation hot refreshing. The updated configuration items are mapped to the Bean attributes, so that when the configuration information is updated, the latest configuration information can be bound into the Bean attributes without restarting the client, and annotation hot refreshing is realized.
It should be noted that, the update operation of the configuration item key cache list is executed in synchronization with the issue operation of the environment change event. Illustratively, after the execution of the issuing operation of the environment change event is ended, the execution of the updating operation of the configuration item key cache list is ended.
According to the technical scheme, a configuration resource list is obtained by acquiring remote configuration information; comparing the local configuration information corresponding to the configuration item key cache list with the remote configuration information, and storing the configuration item key of the last acquired remote configuration information in the configuration item key cache list; triggering a configuration change monitor to start under the condition that the local configuration information is not matched with the remote configuration information, and updating a configuration item key cache list based on the remote configuration information, wherein the configuration change monitor is used for monitoring the configuration change of the configuration item key cache list; when the configuration change monitor monitors the configuration change of the configuration item key cache list, an environment change event is issued; in response to the release of the environment change event, the annotation Bean attribute is updated based on the updated configuration item key cache list so as to realize annotating and thermally refreshing, the configuration item key corresponding to the Bean attribute is obtained based on the configuration item key cache list, under the condition that the configuration item key cache list does not have the corresponding configuration item key, the configuration resource list is traversed again to obtain the corresponding configuration item instead of completely obtaining the corresponding configuration item key from the configuration resource list, the problem that the annotating and thermally refreshing efficiency is low due to the fact that the configuration item key in the configuration resource list is too many is solved, and the annotating and thermally refreshing performance is remarkably improved under the scene that the annotating and the modifying Bean is many, the attribute is many and complex.
