Spring的Aop实现

关于Spring的Aop实现，总结如下

必须的几个包：
asm-2.2.2.jar
asm-commons-2.2.2.jar
asm-util-2.2.2.jar

aspectjrt.jar
aspectjweaver.jar

cglib-nodep-2.1_3.jar

当然，还有：
spring.jar
commons-logging.jar

其他，按需选用
jtds-1.2.2.jar
log4j-1.2.15.jar
proxool-0.9.0RC3.jar

其中的两种实现方式

目标执行类：
package com.shenzhoufu.pay.dao;

import org.springframework.jdbc.core.support.JdbcDaoSupport;

/**
* User: libofeng
* Date: 2008-3-9
* Time: 18:51:35
* Description:todo
*/
public class TestManager extends JdbcDaoSupport {
    public void testTime() {
        getJdbcTemplate().execute("select top 1 * from xxxxx");
        //throw new RuntimeException("i am run into error!!!");
    }
}



一、注解方式

package com.shenzhoufu.pay.aop.aspect;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.util.StopWatch;

/**
* User: libofeng
* Date: 2008-3-10
* Time: 11:59:35
* Description:注解切面
*/
@Aspect
public class AnnotationAspect {
    @Pointcut(value = "execution(* com.shenzhoufu.pay.dao.TestManager.*

(..))")
    private void annotationPointcut() {
    }

    @Around(value = "annotationPointcut()")
    public Object testRun(ProceedingJoinPoint pjp) throws Throwable {
        StopWatch clock = new StopWatch(getClass().getName());
        System.out.println("start Around");
        clock.start(pjp.toShortString());
        Object retVal = pjp.proceed();
        System.out.println("haha, i am working!!!");
        clock.stop();
        System.out.println(clock.prettyPrint());
        System.out.println("stop Around");
        return retVal;
    }
}


配置文件：
<!-- 支持 @AspectJ 标记-->
<aop:aspectj-autoproxy proxy-target-class="true"/>
<bean id="testManager" class="com.shenzhoufu.pay.dao.TestManager"/>
<bean id="annotationAspect"

class="com.shenzhoufu.pay.aop.aspect.AnnotationAspect"/>

二、配置文件方式
切面类：
package com.shenzhoufu.pay.aop.aspect;

import org.aspectj.lang.ProceedingJoinPoint;

/**
* User: libofeng
* Date: 2008-3-10
* Time: 11:33:41
* Description:简单切面类
*/
public class TestAspect {

    public Object  testAspect(ProceedingJoinPoint pjp) throws Throwable {
        // start stopwatch
        System.out.println("start stopwatch");
        Object retVal = pjp.proceed();
        System.out.println("haha, i am working!!!");
        // stop stopwatch
        System.out.println("stop stopwatch");
        return retVal;
    }
}

请特别注意执行目标方法时异常的处理方式，参照 spring Aop 输出方法执行时间
