public class: ExposeInvocationInterceptor [javadoc | source]
java.lang.Object
   org.springframework.aop.interceptor.ExposeInvocationInterceptor

All Implemented Interfaces:
    org.aopalliance.intercept.MethodInterceptor, Serializable

Interceptor that exposes the current org.aopalliance.intercept.MethodInvocation as a thread-local object. We occasionally need to do this; for example, when a pointcut (e.g. an AspectJ expression pointcut) needs to know the full invocation context.

Don't use this interceptor unless this is really necessary. Target objects should not normally know about Spring AOP, as this creates a dependency on Spring API. Target objects should be plain POJOs as far as possible.

If used, this interceptor will normally be the first in the interceptor chain.

public static final  ExposeInvocationInterceptor INSTANCE    Singleton instance of this class 
public static final  Advisor ADVISOR    Singleton advisor for this class. Use in preference to INSTANCE when using Spring AOP, as it prevents the need to create a new Advisor to wrap the instance.
