一个简单的Spring的AOP例子

目标对象的接口:IStudent.java

1 package com.dragon.study;
5
6

目标类:StudentImpl.java

1 package com.dragon.study.Impl;
5
6 import com.dragon.study.IStudent;
7
8

前置通知:BeforeAdvice.java

1 package com.dragon.Advice;
5
6 import java.lang.reflect.Method;
7
8 import org.springframework.aop.MethodBeforeAdvice;
9
10

后置通知:AfterAdvice.java

1package com.dragon.Advice;
5
6import java.lang.reflect.Method;
7
8import org.springframework.aop.AfterReturningAdvice;
9
10

环绕通知:CompareInterceptor.java

1package com.dragon.Advice;
5
6import org.aopalliance.intercept.MethodInterceptor;
7import org.aopalliance.intercept.MethodInvocation;
8
9

配置文件applicationContext.xml

1<?xml version="1.0" encoding="UTF-8"?>

11<bean id="student" class="org.springframework.aop.framework.ProxyFactoryBean">
12 <property name="proxyInterfaces">

14 </property>
15 <property name="interceptorNames">
16 <list>
17 <value>beforeAdvice</value>
18 <value>afterAdvice</value>
19 <value>compareInterceptor</value>

21 </property>
22 <property name="target">
23 <ref bean="studenttarget"/>
24 </property>
25
26</bean>

现在开始写测试类,Test.java

1package com;
5
6import org.springframework.context.ApplicationContext;
7import org.springframework.context.support.FileSystemXmlApplicationContext;

9import com.dragon.study.IStudent;
