1、首先创建一个web项目

文件路径按照自己喜好改变  选择打钩的地方 可以自动创建web.xml

2、建一个studen类

public class Student {
	public String uname;
	public int age;
	public String getUname() {
		return uname;
	}
	public void setUname(String uname) {
		this.uname = uname;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	
}

3、web.xml

<?xml version="1.0" encoding="UTF-8"?>  
<web-app version="2.5"   
    xmlns="http://java.sun.com/xml/ns/javaee"   
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  
    <!-- 应用程序Spring上下文配置 -->  
    <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath*:applicationContext.xml</param-value>
  </context-param>
  
    <!-- spring上下文加载监听器 -->  
    <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>  
  <welcome-file-list>  
    <welcome-file>index.jsp</welcome-file>  
  </welcome-file-list>  
</web-app>  

4.applicationContext.xml 放src下

<?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-3.0.xsd"  
  
    default-lazy-init="false" default-autowire="byName">  
    <bean id="student" class="test.Student">  
        <property name="uname" value="123"/>  
    </bean>  
</beans> 

5、测试

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

public class Test {
	public static void main(String[] args) {  
		ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");  
	    Student user =(Student)ac.getBean("student");  
	    System.out.println(user.uname);  
	}  
}

6、运行成功
