一般的spring的配置都是在XML檔案裡配置，spring2.5之後，spring也支援註解配置。

1、applicaltionContext.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <!-- 配置配置的bean所在包的位置 --> <context:component-scan base-package="com.beckham"/> </beans>

2、model層bean的配置

package com.beckham.model; import org.springframework.stereotype.Repository; //註解 @Repository("user") public class User { private String username ; private String sex ; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } }

3、controller層bean的配置

package com.beckham.daoimp; import org.springframework.stereotype.Controller; import com.beckham.dao.UserDAO; import com.beckham.model.User; //註解 @Controller("userDAO") public class UserDAOImp implements UserDAO { public void add(User user) { System.out.println(user.getUsername()); System.out.println(user.getSex()); } }

3、service層的bean的配置

package com.beckham.service; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.beckham.dao.UserDAO; import com.beckham.model.User; //註解 @Service("userService") public class UserService { //setter注入介面、面向介面程式設計 private UserDAO userdao ; public void add(User user){ userdao.add(user) ; } public UserDAO getUserdao() { return userdao; } //註解 @Resource(name="userDAO") public void setUserdao(UserDAO userdao) { this.userdao = userdao; } }  

4、測試類

package com.test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.beckham.model.User; import com.beckham.service.UserService; public class SpringTest { /** * beckham Dec 28, 2009 1:21:09 PM */ public static void main(String[] args) { ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml"); UserService s = (UserService) ctx.getBean("userService"); User u = (User) ctx.getBean("user"); u.setSex("男"); u.setUsername("高文明"); s.add(u); } }  

執行結果：

高文明

男
