Spring的AOP配置(转)

1.先写一个普通类：

             package com.spring.aop;

             public class Common {
                                    public void execute(String username,String password){
                                                   System.out.println("------------------普通类----------------");
                                    }

             }

2.写一个切面类，用于合法性校验和日志添加：

             package com.spring.aop;

             public class Check {
                                          public void checkValidity(){
                                                         System.out.println("------------------验证合法性----------------");
                                           }

                                 public void addLog(JoinPoint j){
                                                           System.out.println("------------------添加日志----------------");
                                                           Object obj[] = j.getArgs();
                                                           for(Object obj){
                                                                           System.out.println(o);
                                                            }
                                                            System.out.println("========checkSecurity=="+j.getSignature().getName());//这个是获得方法名
                                            }

               }
3.配置AOP，使用XML方式：（注意红色标志的内容）

<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">

  <bean id="common" class="com.spring.aop.Common"/>
  <bean id="check" class="com.spring.aop.Check"/>
  
  <aop:config>
    <aop:aspect id="myAop" ref="check">
      <aop:pointcut id="target" expression="execution(* com.spring.aop.Common.execute(..))"/>
      <aop:before method="checkValidity" pointcut-ref="target"/>
      <aop:after method="addLog" pointcut-ref="target"/>
    </aop:aspect>
  </aop:config>
</beans>
注意：



execution(* com.spring.aop.*.*(..))"/

这样写应该就可以了

这是com.aptech.jb.epet.dao.hibimpl 包下所有的类的所有方法。。

第一个*代表所有的返回值类型

第二个*代表所有的类

第三个*代表类所有方法

最后一个..代表所有的参数。


4.最后写一个测试：

package com.spring.aop;

import org.springframework.beans.factory.BeanFactory;
         import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Client {
                   public static void main(String[] args) {
