今天刚刚学习了Spring�Q�做个简单的例子分��n一下。。�?br />
1、首先，创徏接口BookService(包com.Vy.spring.Biz)

package com.Vy.spring.Biz;

public interface BookService {
    public boolean buy(String userName,String bookName,double price);
}
2、创建接口实现类BookServiceImpl(包com.Vy.spring.BizImpl)

package com.Vy.spring.BizImpl;

import com.Vy.spring.Biz.BookService;

public class BookServiceImpl implements BookService {

    @Override
    public boolean buy(String userName, String bookName, double price) {
        // TODO Auto-generated method stub
        System.out.println("业务�Ҏ��buy开始执�?);
        System.out.println("·"+userName+"购买图书�Q?+bookName);
        System.out.println("·"+userName+"增加�U�分"+(int)(price/10));
        System.out.println("·"+"向物��系�l�下发货�?);
        System.out.println("业务�Ҏ��buy�l�束");
        return true;
    }
}
3、添加spring支持�Q�spring版本�?.5�Q?br />      选择AOP库和Spring Core支持
     下一步修改xml名字为aop.xml
4、编写xml文�g

    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">




            com.Vy.spring.Biz.BookService


            logAdvice




5、创建测试类test�Q�包Test�Q?br /> package Test;

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

import com.Vy.spring.Biz.BookService;

public class test {

    /**
    * @param args
    */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ApplicationContext context=new ClassPathXmlApplicationContext("aop.xml");
        BookService bookService=(BookService)context.getBean("bookService");
        bookService.buy("znLin", "spring in action", 20.00);
    }

}
6、运行测试、显�C�结�?br />
[�pȝ��日志][2011 �q?03 �?21 �?06 �?21 �?28 �U�]buy([znLin, spring in action, 20.0])
业务�Ҏ��buy开始执�?br /> ·znLin购买图书�Q�spring in action
·znLin增加�U�分2
·向物��系�l�下发货�?br /> 业务�Ҏ��buy�l�束
