Class ConcurrencyThrottleInterceptor

java.lang.Object
  extended by org.springframework.util.ConcurrencyThrottleSupport
      extended by org.springframework.aop.interceptor.ConcurrencyThrottleInterceptor
All Implemented Interfaces:
java.io.Serializable, org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor

public class ConcurrencyThrottleInterceptor
extends ConcurrencyThrottleSupport
implements org.aopalliance.intercept.MethodInterceptor, java.io.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.
