cn.taketoday.util.ConcurrencyThrottleSupport

cn.taketoday.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.
