ConcurrencyThrottleInterceptor (Spring Framework 5.2.12.RELEASE API)

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

All Implemented Interfaces:
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.

    Description copied from interface: MethodInterceptor
    Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint.proceed().
    Specified by:
    invoke in interface MethodInterceptor
    Parameters:
    methodInvocation - the method invocation joinpoint
    Returns:
    the result of the call to Joinpoint.proceed(); might be intercepted by the interceptor
    Throws:
    Throwable - if the interceptors or the target object throws an exception
