Spring AOP configuration slices, log system exceptions to log logs

1.spring.xml (the main configuration here is the Operation after-throwingafter throwing the exception)

The place to note is highlighted in yellow, mainly several pointcut bean configurations

 <!--Activate automatic proxy function--<aop:aspectj-autoproxy proxy-target-class  = " True "/> <!--slice bean for system service components--<bean id=" aspectservice  " Span style= "COLOR: #0000ff" >class  = " Com.test.http.utils.AspectService  ></bean> <!--AOP configuration--<aop:config> <!--sound A slice, and inject a slice bean, equivalent to @aspect--and <aop:aspect id= "Simpleaspect" ref= "as Pectservice  > <!--Configure a pointcut equivalent to @pointcut---<aop:pointcut expression= execution  (* com.test.http.ser). *(..))" Id= "Simplepointcut"/> <aop:after-throwing  pointcut-ref= "Si Mplepointcut "method=" Afterthrow "throwing=" ex "/> </aop:aspect> </aop:config> 

2.aspectservice.java (This class is a concrete implementation class for facets)

 Packagecom.test.http.utils;ImportJava.io.File;ImportJava.io.FileOutputStream;Importjava.io.IOException;ImportJava.text.SimpleDateFormat;Importjava.util.Date;Importjavax.servlet.http.HttpServletRequest;ImportOrg.apache.commons.logging.Log;Importorg.apache.commons.logging.LogFactory;ImportOrg.aspectj.lang.JoinPoint;ImportOrg.springframework.web.context.request.RequestContextHolder;Importorg.springframework.web.context.request.ServletRequestAttributes; Public classAspectservice {Private Final StaticLog log = Logfactory.getlog (aspectservice.class); //Configuring a notification after throwing an exception, using a Pointcut registered on method aspect ()     Public voidAfterthrow (Joinpoint joinpoint, Exception ex) {System.out.println ("Into the tangent afterthrowing method ..."); //judging the log output level        if(log.isinfoenabled ()) {Log.info ("Afterthrow" + joinpoint + "\ T" +ex.getmessage ()); }        //Detailed error InformationString errormsg = ""; Stacktraceelement[] Trace=Ex.getstacktrace ();  for(stacktraceelement s:trace) {errormsg+ = "\tat" + S + "\ r \ n"; } System.out.println ("Specific exception information:" +errormsg); System.out.println ("Afterthrow Exception Method name" + Joinpoint + "\ T" +ex.getmessage ()); System.out.println ("Go to the cutting afterthrowing method end!!!" "); //Write Exception LogWritelog (ERRORMSG,JOINPOINT,EX); }            /**     *      * @paramdetailerrmsg Detailed error information *@paramMethod Name * @Description: Log Exception *@author: Ma * @createTime: 2016-10-14*/     Public voidwritelog (String detailerrmsg,joinpoint joinpoint,exception ex) {HttpServletRequest request=((servletrequestattributes) Requestcontextholder.

Getrequest (); //gets the requested URLStringBuffer Requesturl =Request.getrequesturl (); //Get parameter informationString queryString =request.getquerystring (); //encapsulates the full request URL with parameters        if(QueryString! =NULL) {requesturl.

3. Create a test class

 Public void TestMethod (HttpServletRequest request) {      System.out.println ("entry Method");       // System.out.println (Request.getparameter ("username"));      int i = 9/0;}

4. Post-operation log log condition
