1、没有异常的

2、有异常的


1、被代理类接口Person.java

 1 package com.xiaostudy;
 2 
 3 /**
 4  * @desc 被代理类接口
 5  * 
 6  * @author xiaostudy
 7  *
 8  */
 9 public interface Person {
10 
11     public void add();
12     public void update();
13     public void delete();
14 }

2、被代理类PersonImple.java

 1 package com.xiaostudy;
 2 
 3 /**
 4  * @desc 被代理类
 5  * 
 6  * @author xiaostudy
 7  *
 8  */
 9 public class PersonImple implements Person {
10 
11     /**
12      * @desc 实现接口方法
13      */
14     public void add() {
15         System.out.println("add()>>>>>>>>");
16     }
17 
18     @Override
19     public void update() {
20         System.out.println("update()>>>>>>>>");
21 //        int i = 1/0;
22     }
23 
24     @Override
25     public void delete() {
26         System.out.println("delete()>>>>>>>>");
27     }
28     
29 }

3、MyAspectJ.java

 1 package com.xiaostudy;
 2 
 3 import org.aspectj.lang.JoinPoint;
 4 import org.aspectj.lang.ProceedingJoinPoint;
 5 
 6 /**
 7  * @desc 通知类
 8  * 
 9  * @author xiaostudy
10  *
11  */
12 public class MyAspectJ {
13     
14     public void myBefort(JoinPoint joinPoint) {
15         System.out.println("前置通知>>>>>>>>>joinPoint: " + joinPoint.getSignature().getName());
16     }
17     
18     public void myAfterReturning(JoinPoint joinPoint, Object ret) {
19         System.out.println("后置通知>>>>>>>>>joinPoint: " + joinPoint.getSignature().getName()
20                 + ", ret: " + ret);
21     }
22     
23     public Object myAround(ProceedingJoinPoint joinPoint) throws Throwable {
24         System.out.println("环绕通知====前>>>>>>>>>>>");
25         Object obj = joinPoint.proceed();
26         System.out.println("环绕通知====后<<<<<<<<<<<");
27         return obj;
28     }
29     
30     public void myThrowint(JoinPoint joinPoint, Throwable e) {
31         System.out.println("异常通知>>>>>>>>>joinPoint: " + joinPoint.getSignature().getName()
32                 + ", e: " + e.getMessage());
33         System.exit(0);
34     }
35     
36     public void myAfter(JoinPoint joinPoint) {
37         System.out.println("最终通知>>>>>>>>>joinPoint: " + joinPoint.getSignature().getName());
38     }
39 }

4、spring的配置文件applicationContext.xml

 

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 8                               http://www.springframework.org/schema/aop/spring-aop.xsd">
 9     <!-- 创建被代理类 -->
10     <bean id="person" class="com.xiaostudy.PersonImple"></bean>

20             <aop:before method="myBefort" pointcut-ref="myPointcut"/>
21             <!-- 后置通知:returning表示:后置通知的第二个参数名,内容是方法的返回值 -->

29         </aop:aspect>
30     </aop:config>
31 </beans>

 

5、测试类Test.java

 1 package com.xiaostudy;
 2 
 3 import org.springframework.context.ApplicationContext;
 4 import org.springframework.context.support.ClassPathXmlApplicationContext;
 5 
 6 /**
 7  * @desc 测试类
 8  * 
 9  * @author xiaostudy
10  *
11  */
12 public class Test {
13 
14     public static void main(String[] args) {
15         ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
16         Person person = ac.getBean("person", Person.class);
17         person.add();
18         person.update();
19         person.delete();
20     }
21 
22 }
