1、OrderService

package com.clevercode;public class OrderService {private int id;OrderService(){System.out.println("OrderService construct");}public void setId(int id){this.id &＃61; id;}public int getId(){return this.id;}}


2、UserService

package com.clevercode;public class UserService {private String name;UserService(){System.out.println("UserService construct");}public void setName(String name){this.name &＃61; name;}public String getName(){return this.name;}}


Spring-config.xml


<beans xmlns&＃61;"http://www.springframework.org/schema/beans"xmlns:xsi&＃61;"http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation&＃61;"http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"><bean id&＃61;"orderService" class&＃61;"com.clevercode.OrderService"/><bean id&＃61;"userService" class&＃61;"com.clevercode.UserService"/>beans>


新建测试类

package com.clevercode;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test {public static void main(String[] args) {//初始化spring容器ClassPathXmlApplicationContext ac &＃61; new ClassPathXmlApplicationContext("spring-config.xml");//通过class 获取beanOrderService orderService &＃61; ac.getBean(OrderService.class);orderService.setId(10);System.out.println(orderService.getId());//通过name获取beanUserService userService &＃61; (UserService) ac.getBean("userService");userService.setName("CleverCode");System.out.println(userService.getName());}
}
