public class DebugInterceptor
extends SimpleTraceInterceptor

AOP Alliance MethodInterceptor that can be introduced in a chain to display verbose information about intercepted invocations to the logger.

Logs full invocation details on method entry and method exit, including invocation arguments and invocation count. This is only intended for debugging purposes; use SimpleTraceInterceptor or CustomizableTraceInterceptor for pure tracing purposes.

从以下版本开始:

invoke 在类中 AbstractTraceInterceptor

参数:

invocation - the method invocation joinpoint

返回:

the result of the call to Joinpoint.proceed(), might be intercepted by the interceptor.
