Spring AOP surround notification logging app's logs

The framework used is spring mvc+spring

Recently want to take advantage of spring AOP surround notification to handle the Web log problem, in general, if the controller layer to make a cut, it is difficult to monitor the actual operation, in the service layer to cut into the service layer can only monitor the situation, Logging is logged by capturing the exception that is thrown by the service, which is sufficient for the current application to be logged as follows:

Code:

@Component @aspect Public classExceptionlog {/*** 61 * Surround notifications need to carry Proceedingjoinpoint type parameters * 62 * Surround notification is similar to the whole process of dynamic agents: Parameters of the Proceedingjoinpoint type can decide whether to execute the target method     。 * 63 * And the surround notification must have a return value, which is the return value of the target method **/@Around ("Execution (* *com.test.service). *.*(..))")     PublicObject Aroundmethod (Proceedingjoinpoint PJD)throwsthrowable {Object result=NULL; String MethodName= "Class:" + Pjd.gettarget (). GetClass (). GetName () + "method:" + pjd.getsignature (). GetName ();//Get method NameHttpServletRequest Request= ((servletrequestattributes) requestcontextholder.getrequestattributes ()). Getrequest ();//gets the requested URL//Execute target Method        Try {            //front-facing notificationsresult = Pjd.proceed ();//Back to Notifications}Catch(Throwable e) {//Exception Notification//System.out.println ("the method" + MethodName + "occurs expection:" + e); throw e; /Let Spring handle exceptions}finally {           //Record Log        }        returnResult//The result must be returned, otherwise the controller cannot get the result returned by the service (normally)    }}

Spring Configuration:

<aop:aspectj-autoproxy/>

Web. XML configuration (primarily for getting httpservletrequest)

< Listener >        < Listener-class >             org.springframework.web.context.request.RequestContextListener         </  Listener-class>    </listener>
