ConcurrencyThrottleInterceptor (Spring Framework 4.3.30.RELEASE API)

java.lang.Object
- org.springframework.util.ConcurrencyThrottleSupport
- - org.springframework.aop.interceptor.ConcurrencyThrottleInterceptor

所有已实现的接口:
Serializable, Advice, Interceptor, MethodInterceptor
```
public class ConcurrencyThrottleInterceptor
extends ConcurrencyThrottleSupport
implements MethodInterceptor, Serializable
```
Interceptor that throttles concurrent access, blocking invocations if a specified concurrency limit is reached.
Can be applied to methods of local services that involve heavy use of system resources, in a scenario where it is more efficient to throttle concurrency for a specific service rather than restricting the entire thread pool (e.g. the web container's thread pool).
The default concurrency limit of this interceptor is 1. Specify the "concurrencyLimit" bean property to change this value.

    从接口复制的说明: MethodInterceptor
    Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint.proceed().
    指定者:
    invoke 在接口中 MethodInterceptor
    参数:
    methodInvocation - the method invocation joinpoint
    返回:
    the result of the call to Joinpoint.proceed(); might be intercepted by the interceptor
    抛出:
    Throwable - if the interceptors or the target object throws an exception
