第一个spring写的helloworld，好多细节

首先正确的加入组件springsource-tool-suite-3.7.3.RELEASE-e4.5.2-updatesite，然后再在eclipse中加入5个必须的jar包，分别是：

commons-logging-1.2.jar

spring-beans-4.3.0.RELEASE.jar

spring-context-4.3.0.RELEASE.jar

spring-core-4.3.0.RELEASE.jar

spring-expression-4.3.0.RELEASE.jar

这几个jar包在下载的spring-framework-4.3.0.RELEASE-dist中，

然后开始写java程序：

HelloWorld.java类：

package com.mischen.spring.beans;

public class HelloWorld {
private String name;

public void setName(String name) {
this.name = name;
}
public void hello(){
System.out.println("hello:"+name);
}

}

<?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"> 
<!-- 配置bean -->
<bean id="helloWorld" class="com.mischen.spring.beans.HelloWorld">
<property name="name" value="Spring"/>
</bean>

</beans>

package com.mischen.spring.beans;

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

public class Main {
public static void main(String[] args){
//创建HelloWorld的一个对象
//HelloWorld helloWorld=new HelloWorld();
//为name属性赋值
//helloWorld.setName("mischen");
//调用hello()方法

//1.创建Spring的IOC容器对象
ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");

//2.从IOC容器中获取Bean实例
HelloWorld helloWorld=(HelloWorld) ctx.getBean("helloWorld",HelloWorld.class);
//调用hello方法
helloWorld.hello();
}

}
