开发环境
Spring 4.3.0+Myeclipse2015+JDK1.8
准备阶段：
1、新建一Spring01项目，然后新建一个lib文件。将下面的添加到lib文件中
2、将lib文件所有的包导入项目
开发步骤：
1、新建一个Hello.java的类
1 package com.proc.bean; 2 3 public class Hello { 4 5 private String msg; 6 7 public void setMsg(String msg) { 8 this.msg = msg; 9 } 10 public void say(){ 11 System.out.println("Hello "+msg); 12 } 13 }
2、在src文件夹下面新建一个applicationContext.xml文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://www.springframework.org/schema/beans 5 http://www.springframework.org/schema/beans/spring-beans.xsd"> 6 <!-- id：该实例的名称，class：该实例的类型 --> 7 <bean id="helloWorld" class="com.proc.bean.Hello"> 8 <!-- 设置属性msg的值为world --> 9 <property name="msg" value="world"></property> 10 </bean> 11 </beans>
3、代码测试
1 package com.proc.test; 2 3 import org.junit.Test; 4 import org.springframework.context.ApplicationContext; 5 import org.springframework.context.support.ClassPathXmlApplicationContext; 6 7 import com.proc.bean.Hello; 8 9 public class TestSpring { 10 11 @Test 12 public void test1(){ 13 ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml"); 14 Hello hello=(Hello)context.getBean("helloWorld"); 15 hello.say(); 16 } 17 }
结果输出：
六月 23, 2016 3:23:13 下午 org.springframework.context.support.ClassPathXmlApplicationContext prepareRefresh 信息: Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@1637f22: startup date [Thu Jun 23 15:23:13 CST 2016]; root of context hierarchy 六月 23, 2016 3:23:13 下午 org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions 信息: Loading XML bean definitions from class path resource [applicationContext.xml] Hello world
