public final class ExposeInvocationInterceptor extends Object implements MethodInterceptor, PriorityOrdered, Serializable
MethodInvocationas 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 MethodInvocation currentInvocation() throws IllegalStateException
IllegalStateException- if there is no AOP invocation in progress, or if the ExposeInvocationInterceptor was not added to this interceptor chain
@Nullable public Object invoke(MethodInvocation mi) throws Throwable
mi- the method invocation joinpoint
Joinpoint.proceed(); might be intercepted by the interceptor
Throwable- if the interceptors or the target object throws an exception
public int getOrder()
Higher values are interpreted as lower priority. As a consequence,
the object with the lowest value has the highest priority (somewhat
analogous to Servlet
Same order values will result in arbitrary sort positions for the affected objects.
