[spring] spring中aop使用

package com.wa.spring.aop;

/**
 * @author Administrator
 * @Date 2015-02-02 17:06
 *定义切点
 */
public class Log {
    
    //前置通知
    public void before(){
        System.out.println("开始登陆...");
    }
    //环绕通知
    public void login(){
        System.out.println("登录中.....");
    }
    //后置通知
    public void after(){
        System.out.println("登陆后....");
    }
    //after-returning 通知
    public void success(){
        System.out.println("恭喜您，登陆成功...");
    }
    //after-throwing通知
    public void error(){
        System.out.println("登陆出错了....");
    }

}

package com.wa.spring.aop;

/**
 * @author Administrator
 *定义一个切面
 */
public class Operate {
    
    public void parse(){
        String str="3456";
        
        try {
            int s = Integer.parseInt(str);
            System.out.println(s);
        } catch (NumberFormatException e) {
            e.printStackTrace();
            System.out.println(e.getMessage());
        }
    }
    
    

}

bean.xml的配置：

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <bean id="log" class="com.wa.spring.aop.Log">
  </bean>
  <!-- 在aop：config中配置各种通知 -->
  <aop:config>
  <aop:aspect  ref="log"  >
  <!-- 声明切入点 -->
  <aop:pointcut expression="execution(* com.wa.spring.aop.Operate..*(..))" id="operate"/>

   -->
  <aop:after-throwing method="error" pointcut-ref="operate"  arg-names="e" throwing="测试异常"/>

  </aop:aspect>
  </aop:config>

</beans>

测试：

package com.wa.spring.aop;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;


public class AOPTest {
    
    public static void main (String[] args) {
        
        ApplicationContext txt = new 
                ClassPathXmlApplicationContext("com/wa/spring/aop/bean.xml");
        
        Operate operate = (Operate) txt.getBean("ope");
        operate.parse();
    }

}
