Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The method for isolating and limiting current provided by the invention is described below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of an alternative method for isolating current limitation according to the present invention, and as shown in fig. 1, the method may include the following steps:
step S101: and searching a method body added with a preset isolation current limit annotation in a business system framework.
The service system framework is a system framework capable of realizing services with a plurality of functions, the service system framework comprises method bodies corresponding to all the functions, and the corresponding functions can be realized by executing each method body; in this embodiment, a method body to which a preset isolated current limit annotation is added is searched in a business system framework including a plurality of method bodies.
The isolated current limit annotation is an annotation added to a method body required to have an isolated current limit function, and the isolated current limit annotation is encapsulation of the @ HystrixCommand annotation of the Hystrix component. Because there are multiple methods corresponding to each function in a service system framework, and when the service system is in high concurrency access, the problem that the methods cannot be executed easily occurs, which greatly affects the whole service system, the methods in the service system framework need to be isolated and limited in current, thereby protecting the service system in high concurrency environment to a certain extent and reducing the risk of the service system being dragged down. Therefore, when a developer constructs a business system framework, a preset isolation current-limiting annotation is introduced to each method body, so that the effect of isolating and limiting current of each method body is realized through the preset isolation current-limiting annotation.
The Hystrix component provides functions of fusing, isolating, current limiting and the like, and can ensure that a service system is still available when one or more method bodies simultaneously have problems; in the prior art, if a Hystrix component is to be used, an @ Hystrix command annotation needs to be added to a method body with an isolated current limiting function, however, in the @ Hystrix command annotation, a developer needs to perform parameter setting on all configuration items required by the Hystrix component in code, for example: timeout time, fusing threshold, maximum allowed thread count; therefore, developers are required to understand the meaning and use of each configuration item in the Hystrix component, and are required to spend a lot of time to understand the running mechanism of the Hystrix component and the scene to which the configuration item is applied; in the embodiment, the simplified isolated current limit annotation is used to replace the complex @ hystrix command annotation, in the isolated current limit annotation, the developer only needs to perform parameter setting on the configuration item of particular interest, and the parameter values of other configuration items use default values.
The annotation is an extended template of a method body, and the method body can realize corresponding functions according to rules in the annotation. In this embodiment, if a certain method body needs to use the Hystrix component, only developers need to call a self-defined isolation current-limiting annotation in the method body, and set parameter values of key configuration items in the isolation current-limiting annotation.
It should be further noted that, in the present embodiment, only customized isolated current limit annotations can be added to the method body of type public.
Step S102: and obtaining parameter values of key configuration items from the isolated current-limiting annotation, searching an initial parameter group corresponding to the service system framework from a preset background management platform, and obtaining initial parameter values of other configuration items except the key configuration items from the searched initial parameter group.
Wherein the key configuration item is a configuration item contained in the isolated current limit annotation;
the background management platform stores initial parameter sets corresponding to all the service system frames respectively;
each initial parameter set includes initial parameter values for various configuration items required by the Hystrix component.
In the embodiment, in the isolation current-limiting annotation, a developer only needs to set parameter values of key configuration items, and parameter values of other configuration items required by the Hystrix component are obtained from the background management platform; storing initial parameter sets of different types of service system frameworks in a background management platform, wherein each initial parameter set comprises initial parameter values of various configuration items required by a Hystrix component; because a certain difference exists between the service systems, the parameter values of the same configuration item of different service systems may have a difference, and therefore, a developer may set initial parameter values for each configuration item of each service system in the background management platform according to the service requirements and the historical experience values.
For example, if the annotation of the isolated current limit includes parameter values of maxRequest (maximum concurrency) and timeout (timeout), the initial parameter values of the other configuration items except maxRequest (maximum concurrency) and timeout (timeout) need to be obtained from the corresponding initial parameter set in the backend management platform.
Specifically, the searching for the initial parameter set corresponding to the service system framework from the preset background management platform specifically includes:
and searching an initial parameter value corresponding to the service system framework from the background management platform according to the configuration file of the service system framework.
Step S103: and constructing the @ HystrixCommand annotation of the Hystrix component according to the parameter values of the key configuration items in the isolated current-limiting annotation and the initial parameter values of other configuration items acquired from the background management platform.
Specifically, step S103 includes:
acquiring a preset @ HystrixCommand annotation template; wherein the annotation template only comprises various configuration items required by the Hystrix component;
correspondingly adding parameter values of key configuration items in the isolated current limiting annotation into the annotation template;
and correspondingly adding the initial parameter values of other configuration items acquired from the background management platform into the annotation template.
Since the code format of the @ Hystrix command annotation is fixed, and a developer is required to perform parameter setting on each configuration item during use, in this embodiment, the @ Hystrix command annotation can be automatically generated according to the code format of the @ Hystrix command annotation according to parameter values of key configuration items in the isolated current-limiting annotation and initial parameter values of other configuration items acquired from the background management platform, so that the isolated current-limiting function of the Hystrix component is realized.
Step S104: and carrying out isolated current limiting processing on the method body according to the constructed @ HystrixCommand annotation.
Specifically, step S104 includes:
determining an isolation current limiting mode corresponding to the isolation current limiting annotation according to the type of the configuration item in the isolation current limiting annotation; wherein, the isolation current limiting mode includes: a semaphore isolation mode, a thread pool isolation mode and a fusing mode;
and carrying out isolation current limiting treatment on the method body according to the determined isolation current limiting mode.
Further, the determining, according to the type of the configuration item in the isolated current limit annotation, an isolated current limit manner corresponding to the isolated current limit annotation includes:
when the types of the key configuration items in the isolation current limit annotation are: when command name commandKey, group name commandGroup to which the command belongs and service degradation method fallback are used, the isolation current limiting mode corresponding to the isolation current limiting annotation is a semaphore isolation mode;
when the types of the key configuration items in the isolation current limit annotation are: when command name commandKey, command group name, service degradation method fallback and isolation strategy isolationStgy are used, the isolation current-limiting mode corresponding to the isolation current-limiting comment is a thread pool isolation mode;
when the types of the key configuration items in the isolation current limit annotation are: when the command name commandKey, the group name commandGroup to which the command belongs, the service degradation method fallback, the request threshold requestThreshold and the failure threshold errorThreshold, the isolation current limiting mode corresponding to the isolation current limiting annotation is a fusing mode.
For example, when using the @ Phystrix note as the isolated current limit note; when the isolated current limiting mode corresponding to the @ Phystrix annotation is a semaphore isolated mode, examples of the @ Phystrix annotation are as follows:
@Phystrix(commandKey＝"getProfile",commandGroup＝"getProfile",fallBack＝"fail",maxRequest＝50,timeout＝2000)
publicProfileDOgetUserProfile(String userId){
//TODO
}
wherein, the value of commandKey is consistent with the body name of the method; the value of the commandGroup is consistent with the class name of the class to which the method body belongs; the value of the failback reflects the adopted service degradation mode, the parameter value is consistent with the original method body, configuration is usually needed, and the method body mainly comprises the contents of quick failure return or alarm and generally does not relate to business logic;
maxRequest is the maximum allowed concurrency, timeout is the timeout; in this example, maxRequest and timeout are key configuration items; the default value of maxRequest in the background management platform is 500, and the default value of timeout is 1000ms; but in this example, the developer sets the parameter value for maxRequest to 50 and the parameter value for timeout to 2000ms.
For another example, when the isolation and current limiting mode corresponding to the @ Phystrix annotation is the thread pool isolation mode, the @ Phystrix annotation is exemplified as follows:
when a thread pool isolation mode is adopted, a configuration item 'isolationStgy' needs to be added into the @ Phystrix annotation; if the configuration item "isolationStgy" is not present in the @ Phystrix annotation, then semaphore isolation is used.
timeout is timeout, and threadpool size is thread pool size; in this example, timeout and threadPoolSize are key configuration items.
In this embodiment, depending on hystrix-core, using spring AOP and using a self-defined isolated current-limiting annotation as a tangent point, in the method invocation process of adding the isolated current-limiting annotation, constructing an @ HystrixCommand object, and using parameter values of key configuration items in the isolated current-limiting annotation in the constructed @ HystrixCommand object, while using initial parameter values stored in a background management platform for parameter values of other configuration items. The scheme is that @ HystrixCommand annotation is constructed according to isolation current-limiting annotation; therefore, the Hystrix component can be called by adding the method body of the isolation current-limiting annotation, and the isolation current-limiting function is achieved.
Still further, the method further comprises:
and receiving an initial parameter modification instruction, and modifying the initial parameter values of the corresponding configuration items in the corresponding service system framework in the background management platform according to the initial parameter modification instruction.
In the prior art, after the @ HystrixCommand annotation is constructed, the parameter value of the configuration item in the @ HystrixCommand annotation cannot be modified, and if the parameter value of the configuration item needs to be modified, the @ HystrixCommand annotation needs to be reconstructed; in this embodiment, the developer may modify the initial parameter value of the configuration item through the background management platform.
In this embodiment, a developer can execute processing logic corresponding to isolation current limiting only by adding a self-defined isolation current limiting annotation to a method body required to have an isolation current limiting function; when the isolated current-limiting annotation is quoted, if the developer does not set parameters for the key configuration items in the isolated current-limiting annotation, the initial parameter values of the configuration items in the background management platform are used; if the developer sets parameters for the key configuration items in the isolated current limit annotation, the parameter values in the isolated current limit annotation are used.
