spring 3.0 aop 实例

花了一下午终于调试成功了，发上去做个纪念。
需要的jar
导入了dist里面的所有jar
从外部找的jar共有5个：
commons-logging-1.1.1.jar
aspectjrt.jar(下载aspectj安装，从其lib路径中拷出)
aspectjweaver.jar(下载aspectj安装，从其lib路径中拷出)
cglib-2.2.jar
aopalliance.jar

//Person.java
package com.aabnn.entity;

public interface Person {
	public void readBook(String book);
}
//Chinese.java
//----------------------------------------------------
package com.aabnn.entity;

public class Chinese implements Person{

	@Override
	public void readBook(String book) {
		// TODO Auto-generated method stub
		System.out.println("I am reading a new book,the book name is:"+book);
	}

}
//LogAspect.java
//---------------------------------------------------
package com.aabnn.aspect;

import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;

@Aspect
public class LogAspect {
	@After("execution(* *.*.*.*.*(..))")
	public void logTest(){
		System.out.println("executing aop testing...");
	}
}
//SpringTwoTest
package com.aabnn.test;


import org.springframework.context.ApplicationContext;

		Person p=(Person)ctx.getBean("chinesePerson");

pyzheng 写道

System.out.println("executing aop testing..."); 
-------------------------
为什么执行了这句两次？

去掉配置中的 <context:component-scan base-package="com.aabnn.*"> 
        <context:include-filter type="annotation" 
           expression="org.aspectj.lang.annotation.Aspect" /> 
    </context:component-scan> 
就可以了
