Embodiment one
The method of isolation current limliting provided by the invention is illustrated with reference to the accompanying drawing.
Fig. 1 is a kind of optional flow diagram of the method for present invention isolation current limliting, as shown in Figure 1, this method can be with
The following steps are included:
Step S101: the method body explained added with preset isolation current limliting is searched in operation system frame.
Wherein, the operation system frame is the system framework that the business of multiple functions can be achieved, in the operation system
Include method body corresponding with each function in frame, corresponding function may be implemented by executing each method body；In this reality
It applies in example, the method that preset isolation current limliting is explained that is added to is searched in the operation system frame for including multiple method bodies
Body.
It is the note added on the method body for needing to have isolation current-limiting function, the isolation that the isolation current limliting, which is explained,
It is the encapsulation explained the@HystrixCommand of Hystrix component that current limliting, which is explained,.Due to the meeting in an operation system frame
There are multiple method bodies corresponding with each function, and when operation system is under high concurrent access, the method body of being easy to appear cannot
The problem of being performed causes very big influence to entire operation system, thus need to the method body in operation system frame into
Row isolation current limliting reduces the wind that operation system is worn down to carry out certain protection to the operation system under high concurrent environment
Danger.Therefore, developer can introduce preset isolation current limliting on each method body and explain when constructing operation system frame,
The effect that isolation current limliting is carried out to each method body is realized to explain by preset isolation current limliting.
Hystrix component provides the functions such as fusing, isolation, current limliting, can occur simultaneously in one or more method bodies
Guarantee that operation system still can be used when problem；In the prior art, it if it is desired that with Hystrix component, needs that there is isolation
@HystrixCommand is added on the method body of current-limiting function to explain, however in@HystrixCommand note, it needs out
Hair personnel carry out parameter setting to all configuration items required for Hystrix component in code, such as: time-out time, fusing
Threshold value, maximum allowable Thread Count；The meaning and use of each configuration item in Hystrix component are understood therefore, it is necessary to developer
On the way, the scene that developer takes a significant amount of time the operating mechanism for understanding Hystrix component and configuration item is applicable in is needed；And
In the present embodiment, explained using simplified isolation current limliting to substitute complicated@HystrixCommand and explain, in isolation current limliting
Developer only needs to carry out parameter setting to the configuration item of special attention in note, and the parameter value of other configurations item then uses
Default value.
Note is the expansion templates of a method body, and method body can realize corresponding function according to the rule in note.
In the present embodiment, if some method body needs only to need developer to call in party's body of laws using Hystrix component
Customized isolation current limliting is explained, and the parameter value of key configuration item is arranged in isolation current limliting is explained.
It should also be noted that, in the present embodiment, being only capable of adding on the method body that type is public customized
Current limliting is isolated to explain.
Step S102: the parameter value of key configuration item is obtained from the isolation current limliting note, from preset back-stage management
Corresponding with operation system frame initial parameter group is searched in platform, and from the initial parameter group found acquisition in addition to
The initial parameter value of other configurations item except the key configuration item.
Wherein, the key configuration item is included in the configuration item in the isolation current limliting note；
The background management platform is stored with initial parameter group corresponding with each operation system frame respectively；
Each initial parameter group includes the initial parameter value of each configuration item required for Hystrix component.
In the present embodiment, in isolation current limliting is explained, developer only needs to carry out parameter value to key configuration item
Setting, and the parameter value of other configurations item required for Hystrix component is then obtained from background management platform；In back-stage management
It is stored with the initial parameter group of different types of operation system frame in platform, and includes in each initial parameter group
The initial parameter value of each configuration item required for Hystrix component；Due to that can have certain difference between each operation system
Different, so there may be differences for the parameter value of the same configuration item of different business systems, therefore, developer can be according to business
Demand and historical experience value are that initial parameter is respectively set in each configuration item of each operation system in background management platform
Value.
For example, if including key configuration item maxRequest (maximum concurrency) and timeout in the note of isolation current limliting
The parameter value of (time-out time), then need from the corresponding initial parameter group in background management platform obtain in addition to
The initial parameter value of other configurations item except maxRequest (maximum concurrency) and timeout (time-out time).
Specifically, described search initial parameter corresponding with the operation system frame from preset background management platform
Group specifically includes:
According to the configuration file of the operation system frame, searched and the operation system from the background management platform
The corresponding initial parameter value of frame.
Step S103: according to the isolation current limliting explain in key configuration item parameter value and from the back-stage management
The initial parameter value of the other configurations item obtained in platform, the@HystrixCommand for constructing Hystrix component are explained.
Specifically, step S103, comprising:
It obtains preset@HystrixCommand and explains template；Wherein, the note template only includes Hystrix component
Required each configuration item；
It is corresponding to be added in the note template by the parameter value of the key configuration item in the isolation current limliting note；
It is corresponding to be added to the note by the initial parameter value of the other configurations item obtained from the background management platform
It solves in template.
Since the@HystrixCommand code format explained is fixed, need developer to each configuration when in use
Carry out parameter setting, so in the present embodiment, can be explained according to isolation current limliting in key configuration item parameter value with
And the initial parameter value of the other configurations item got from background management platform, the code explained according to@HystrixCommand
Format automatically generates@HystrixCommand note, to realize the isolation current-limiting function of Hystrix component.
Step S104: it is explained according to the@HystrixCommand constructed and isolation current limliting processing is carried out to the method body.
Specifically, step S104, comprising:
According to it is described isolation current limliting explain in configuration item type, determine it is corresponding with the isolation current limliting note every

When name commandGroup, service degradation method fallback, the isolation current limliting explains corresponding isolation current-limiting mode and is
Semaphore isolation method；
When the type of the key configuration item in the isolation current limliting note are as follows: group belonging to command name commandKey, order
When name commandGroup, service degradation method fallback, isolation strategy isolationStgy, the isolation current limliting is explained
Corresponding isolation current-limiting mode is thread pool isolation method；
When the type of the key configuration item in the isolation current limliting note are as follows: group belonging to command name commandKey, order
Name commandGroup, service degradation method fallback, request threshold value requestThreshold, failure threshold value

Isolation current-limiting mode be semaphore isolation method when ,@Phystrix explain example it is 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 method body name；Class belonging to the value and method body of commandGroup
Class name is consistent；The value of fallBack reflects the service degradation mode of use, and parameter value is consistent with original method body, usually needs
It configures, the content for mainly quickly unsuccessfully returning or alerting in method body is not related to service logic generally；
MaxRequest is the maximum concurrency allowed, and timeout is time-out time；In this example, maxRequest
It is key configuration item with timeout；The default value of maxRequest is the default value of 500, timeout in background management platform
For 1000ms；But in this example, developer by the parameter value of maxRequest sets 50, by the parameter of timeout
Value is set as 2000ms.
In another example when it is thread pool isolation method that the@Phystrix, which explains corresponding isolation current-limiting mode ,@
The example that Phystrix is explained is as follows:
Wherein, it when using thread pool isolation method, needs to add configuration item in@Phystrix note
"isolationStgy"；If configuration item " isolationStgy " is not present in@Phystrix note, semaphore is used
Isolation method.
Timeout is time-out time, threadPoolSize is thread pool size；In this example, timeout and
ThreadPoolSize is key configuration item.
In the present embodiment, hystrix-core is relied on, is explained and is made with customized isolation current limliting using spring AOP
@HystrixCommand object is constructed, and in structure in being added to the method body calling process that isolation current limliting is explained for point of contact
In the@HystrixCommand object built using isolation current limliting explain in key configuration item parameter value, and other configurations item
Parameter value use the initial parameter value stored in background management platform.This programme is to explain building@according to isolation current limliting
