Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As described in the background art, in the prior art, the related operations and the service logic processing of the lock are operated in one system, which is intuitive, clear and easy to understand, however, there are two problems after the coupling, on one hand, if the operation of releasing the lock is not executed yet in the process of executing the code, if the server goes down at this time, the program is interrupted, thereby greatly reducing the flexibility of the code; on the other hand, distributed locks are possibly used in the current scenes of all systems, the implementation logics are basically similar, if each set of system writes one set of logic, the cost is increased, redundancy is caused, and the code maintenance efficiency is reduced.
In order to solve the above problem, an embodiment of the present invention provides a processing method for executing a distributed lock operation, as shown in fig. 1, where the method includes:
101. and when the project object model file is operated, detecting whether a preset annotation mark exists or not.
Xml file for describing maven coordinates of the Project, the file for managing source code, configuration files, dependency relationships of the Project, and the like, is a configuration file at Project level. The preset annotation mark can be a custom annotation marked in advance through attribute information, and the preset annotation mark can be used for marking a method needing to cut into a tangent plane, so that when the preset annotation mark is detected, the preset annotation mark can jump to the preset tangent plane. Specifically, when a project object model file is operated, the file information is traversed, and the detected preset annotation identification is fed back.
102. And if the preset annotation identification is detected, analyzing whether the configuration items configured in the project configuration file corresponding to the preset annotation identification meet the preset distributed lock execution condition.
The project configuration file corresponding to the preset annotation identification may include a configuration file of a project management tool (Maven) or a project automation building tool (Gradle). The configuration item may specifically include spring distributed-lock enable, and the configuration item may be used to determine whether to trigger a corresponding initiator. Specifically, if the preset annotation identifier is detected, a corresponding project configuration file may be searched according to the preset annotation identifier, configuration item information configured in the project configuration file is analyzed, and it is determined whether a configuration item configured in the project configuration file meets a preset distributed lock execution condition, for example, it is determined that a state of the configuration item spring.
103. And if so, indicating the current thread to jump to a section configured in the project configuration file, and executing distributed lock operation by triggering a starter configured in the project configuration file.
If the configuration items configured in the project configuration file corresponding to the preset annotation identifier meet the preset distributed lock execution condition, jumping to a section configured in the project configuration file, where the section may be configured in the configuration file in advance, and the section may be used to extract and position codes related to non-business logic to a specific connection point. The launcher may be pre-configured in a project configuration file. The performing distributed lock operations may include locking and unlocking operations.
Further, in order to better explain the process of the processing method for executing the distributed lock operation, as a refinement and an extension to the above embodiment, the embodiment of the present invention provides several alternative embodiments, but is not limited to this, and specifically as follows:
in an alternative embodiment of the present invention, the method may further comprise: pre-configuring an annotation identifier by utilizing attribute mark information, and configuring a tangent plane connected with the annotation identifier; and configuring parameter information in the project configuration file, wherein the parameter information comprises configuration items, a starter, a preset annotation mark and a tangent plane.
For the embodiment of the present invention, the pre-configuring the annotation identifier by using the attribute flag information specifically may include: defining lock-related attributes, such as presetting annotation identification by using attribute mark information such as key prefix-key prefix, key value, lock automatic release time-leaseTime and whether locking is blocked-isBlock, for example: the preset annotation flag may be set to @ DistributedLock (keyPrefix ═ app _ lock ═ key ═ userld ═ isBlock ═ false); the configuration items in the configuration files can automatically find the configuration items through the automatic configuration function of Spring when the Spring is started, the section class of the distributed lock is initialized into a Spring container according to whether the parameter of the Spring distributed-lock enabled configuration item is true, and the redisonson client is received as an entry parameter for subsequent judgment, wherein the Spring framework is an open source Java platform and can be used for providing comprehensive infrastructure for easily and quickly developing durable Java application programs; the configuring the launcher in the project configuration file may specifically include: when the starter is configured, only the corresponding configuration files which depend on the added Maven or Gradle need to be automatically configured through SpringBoot, and the SpringBoot is a framework for simplifying the Spring development and can be used for monitoring the Spring application development. The SpringBoot instantiates the classes and performs automatic configuration as follows: firstly, searching resources/META-INF/spring.factors in a dependent starter package when the SpringBoot is started; secondly, loading the AutoConfigure class according to spring. Finally, according to the condition of the @ Conditional annotation, automatic configuration is performed and the Bean is injected into the Context of the Spring Context.
In another alternative embodiment of the present invention, the step 102 may specifically include: and correspondingly searching the project configuration file according to the analyzed preset annotation identification, and judging whether the configuration item parameter in the configuration file is a first preset threshold value.
For the embodiment of the invention, when the project code file is executed, if the preset annotation identifier is detected, the project configuration file corresponding to the preset annotation identifier is correspondingly searched, whether the configuration item parameter in the configuration file is a first preset threshold value is judged, if the configuration item parameter is the first preset threshold value, the configuration file jumps to a preset section, the starter is triggered, and corresponding locking and unlocking operations are executed. The preset annotation mark can be a custom annotation based on java language, and is used for defining general attributes including lock name, prefix, automatic release time and the like, and the attributes of the distributed locks can be manually set without writing redundant codes, so that the codes can be greatly simplified. The specific steps may include: configuring keys of static stage prefixes and dynamic expressions of the keys, wherein the keys are specifically configured to be included by using single quotation marks of character strings; the time for automatically releasing the lock is configured, the time is taken as a second unit, the default time can be 60 seconds, and whether the lock is blocked or not is judged.
In yet another alternative embodiment of the present invention, the step 103 may specifically include: and if the configuration item parameter in the configuration file is a first preset threshold value, indicating that the current thread jumps to a section configured in the project configuration file, triggering a starter configured in the project configuration file, and executing locking and unlocking operations.
Wherein the first preset threshold may be true. Specifically, whether a parameter of a spring/distributed-lock/enable configuration item in the configuration is true is judged, if so, a section corresponding to the preset annotation identifier is called, a starter configured in the configuration file is triggered, and locking and unlocking operations are executed.
For the embodiment of the present invention, corresponding to the step 103, the method may further include: and if the configuration item parameter in the configuration file is a second preset threshold value, not jumping to a section configured in the project configuration file, and continuously detecting the preset annotation mark.
The second preset threshold may be false specifically. Specifically, it is determined whether a parameter of a spring distributed-lock enabled configuration item in an application properties configuration file of the project is false, if the parameter is false, the current code file is executed continuously without jumping to a section configured in the project configuration file, and the preset annotation identifier is detected.
In yet another alternative embodiment of the present invention, the step 103 may further include: creating a spring section by adopting a section-oriented programming AOP technology, and setting a code corresponding to the starter in the section; and when the configuration item parameter in the configuration file is a first preset threshold value, intercepting a section configured in the project configuration file, and executing distributed locking operation by triggering a starter configured in the project configuration file.
For the embodiment of the present invention, after it is determined that the configuration item satisfies the preset distributed lock execution condition, the spring AOP technology may be used to perform AOP interception on the method that detects the preset annotation identifier, and the execution method of the distributed lock is switched in through the preset tangent plane connection point. Specifically, the cut surface can be specified as a method for detecting the @ distributedLock annotation through a spring AOP cut surface technology, when the method is called, the cut surface is executed first, the relevant attributes defined by the preset annotation identification can be acquired in the cut surface, and then locking and unlocking operations are executed.
In yet another alternative embodiment of the present invention, the method may further comprise: and loading a redisson client and establishing connection between the client and a redis database.
For the embodiment of the invention, the precondition needs to be judged before the trigger of the initiator, including whether an initialized RedissonClient client exists in the spring container currently. Because the premise that the starter (starter) realizes distributed lock control is based on redisson, a redis server needs to be connected, namely a client connected with the redis is needed, the connected client is initialized, and when the code starts to run, the client is loaded, the connection with the redis is established, and important precondition is provided for subsequent operation. It should be noted that, for the embodiment of the present invention, after the redisson client is loaded, information such as a connection address, a port, and a password with a configuration attribute of redis may also be added to the configuration file, so as to establish the connection of the redis.
In practical applications, the configured Project files may be packaged into a distributed lock package, and the package may be imported into a Project Object Model (POM) file or a gradle file of the Project to be executed. And when the project is executed, if the preset annotation mark is detected, skipping to the tangent plane and executing the logic of the distributed lock, thereby achieving the purpose of controlling the distributed lock. For the distributed lock program package, because the package is already performed, when the project is executed, only the program package needs to be introduced, and the corresponding preset annotation identification needs to be detected. The program package can be based on the property that the software is used after being opened from a box, namely, a starter is packaged in advance, and the control logic of the distributed lock is realized by the starter, so that the code execution is separated from the control of the distributed lock, the code realization is simplified, and the reusability of the starter is improved.
