Spring AOP使用（基于XML Schema）

　　本文主要简单的介绍了如何基于XML Schema方式使用AOP。本文测试使用的是Spring3.1  + AspectJ1.6.

1.IHelloWord.java

package com.SpringAOP.HelloWord;

public interface IHelloWord {
    public  void sayHello(String message);
}

2.HelloWord.java

package com.SpringAOP.HelloWord;

public class HelloWord implements IHelloWord {
    public void sayHello(String message){
        System.out.println(message);
        //int i=10/0;
    }
}

3.HelloWordAspect.java

package com.SpringAOP.HelloWord;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;

public class HelloWordAspect {
    public void beforeSayHello(JoinPoint joinPoint){
        
        System.out.println("Before :"+joinPoint.getArgs()[0]);
    }
    
    public void afterSayHello(String message){
        System.out.println("After : "+message);
    }
    
    public void aroundSayHello(ProceedingJoinPoint joinPoint) throws Throwable{
        System.out.println("Around Before !! ");
        joinPoint.proceed();
        System.out.println("Around After !! ");
    }
    
    public void afterThrowingSayHello(Exception ex){
        System.out.println("After Throwing : "+ex.getMessage());
    }
    

    public void afterReturningSayHello(String reval){
        System.out.println("After Returning : "+reval);
    }
}

4.HelloWord.xml

<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"

    <bean class="org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator" />
    <bean id="helloWordAspect" class="com.SpringAOP.HelloWord.HelloWordAspect"></bean>
    <bean id="helloWord" class="com.SpringAOP.HelloWord.HelloWord"></bean>
    
    <aop:config>
        <aop:aspect ref="helloWordAspect">
            <aop:before method="beforeSayHello" pointcut="execution(* com.SpringAOP.HelloWord.HelloWord.*(..))"/>
            <aop:after-returning method="afterReturningSayHello" pointcut="execution(public void com.SpringAOP.HelloWord.HelloWord.sayHello(..))" returning="reval"/>
            <aop:after method="afterSayHello" pointcut="execution(public void com.SpringAOP.HelloWord.HelloWord.sayHello(..)) and args(message)"/>
            <aop:after-throwing method="afterThrowingSayHello" pointcut="execution(public void com.SpringAOP.HelloWord.HelloWord.sayHello(..))" throwing="ex"/>
            <aop:around method="aroundSayHello" pointcut="execution(public void com.SpringAOP.HelloWord.HelloWord.sayHello(..))"/>
        </aop:aspect>
    </aop:config>
</beans>

5.HelloWordTest.java

package com.SpringAOP.HelloWord;

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


public class HelloWordTest {
    
    @Test
    public void test(){
        ApplicationContext ctx =new ClassPathXmlApplicationContext("com/SpringAOP/HelloWord/HelloWord.xml");
        
        IHelloWord helloWord = (IHelloWord)ctx.getBean("helloWord");
        helloWord.sayHello("Hello Word!!");
    }
}

6.需要导入的包
