1、新建Helloworld类:

package com.cmm;public class HelloWorld {private String name;public void setName(String name) {this.name = name;}public void say(){System.out.println("hello:"+this.name);}}

2、新建xml文件,注意,在src目录上右键新建。


<?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-4.3.xsd"><bean id="hello" class="com.cmm.HelloWorld"><property name="name" value="cmm"></property></bean></beans>

3、测试如下:

package com.cmm;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Main {public static void main(String[] args) {ApplicationContext context = new ClassPathXmlApplicationContext("AppCtx.xml");HelloWorld hello = (HelloWorld)context.getBean("hello");hello.say();}}


今天只是基础入门,暂时不讲细节。注意一点:xml的目录结构。
