1.首先创建web工程，之后导入Spring jar包，目录如下

2.文件代码

2.1AfterAdvice

package com.niit.aop;import java.lang.reflect.Method;import org.springframework.aop.AfterReturningAdvice;/* * 后置通知 * havingClass方法执行之后才执行。 * 输出日记 * */public class AfterAdvice implements AfterReturningAdvice { @Override public void afterReturning(Object arg0, Method arg1, Object[] arg2, Object arg3) throws Throwable { // TODO Auto-generated method stub System.out.println("后置拦截:下课之后写作业"); }}

2.2BeforeAdvice

package com.niit.aop;import java.lang.reflect.Method;import org.springframework.aop.MethodBeforeAdvice;public class BeforeAdvice implements MethodBeforeAdvice {/* * 前置通知 * 在havingClass切入点方法执行之前通知 * 用于验证用户的合法性。/判断一些数据是否存在。适用于检索。注册判断用户名是否存在。 * */ @Override public void before(Method arg0, Object[] arg1, Object arg2) throws Throwable { // TODO Auto-generated method stub System.out.println("前面拦截:上课之前要点名！在调用havingClass方法之前调用"); }}

2.3StudentIntercepter

package com.niit.aop;import org.aopalliance.intercept.MethodInterceptor;import org.aopalliance.intercept.MethodInvocation;public class StudentIntercepter implements MethodInterceptor { @Override public Object invoke(MethodInvocation method) throws Throwable { // TODO Auto-generated method stub if(method.getArguments().length>0) { String name=(String)method.getArguments()[0]; if("hmq".equals(name)){ System.out.println("中间拦截:你是hmq"); } else { System.out.println("中间拦截:你是学生"); } method.proceed(); } return null; }}

2.4StudentIF

package com.niit.logic;public interface StudentIF { public void havingClass(String name); public void dohomework(String name); }

2.5Student

package com.niit.logic;public class Student implements StudentIF { //作为aop的目标方法public void havingClass(String name) { System.out.println("aop的目标方法"); System.out.println(name+"正在上课");}public void dohomework(String name) { System.out.println(name+"正在写作业");}}

2.6StudentLogic

package com.niit.logic;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class StudentLogic { public static void main(String[] args) { ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml"); StudentIF s=(StudentIF)context.getBean("student"); s.havingClass("hmq"); System.out.println("---------------"); s.dohomework("hmq"); System.out.println("---------------"); s.havingClass("abc"); System.out.println("---------------"); s.dohomework("abc"); System.out.println("---------------"); }}

2.7applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://.niit.exception.MyExceptionHandler"/> --></beans>
