## 4.创建applicationContext.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"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd">
         
         
         <bean id="userDao" class="com.sxt.dao.impl.UserDaoImpl"></bean>
         
         
         <bean id="userService" class="com.sxt.serivce.impl.UserServiceImpl">
         	<property name="userDao" ref="userDao"></property>
         </bean>
         
         
         <bean id="userAction" class="com.sxt.action.UserAction">
         	<property name="userService" ref="userService"></property>
         </bean>
         
    </beans>

## 5.测试 ##

public class TestPro {
        
    
    	public static void main(String[] args) {
        
    		//创建Spirng的工厂对象
    		ApplicationContext context=new  
    		ClassPathXmlApplicationContext("classpath:applicationContext.xml");
    		//从IOC容器里面取对象
    //		UserAction userAction=(UserAction) context.getBean("userAction");  
    //userAction 指<bean id="userAction">
    //		userAction.loadUserById();
    		UserAction userAction = context.getBean(UserAction.class);
    		userAction.loadUserById();
    		
    	}
    }
