spring 第一个helloWord程序

main 主程序：

package sPRing;import org.springframework.context.applicationContext;import org.springframework.context.support.ClassPathxmlApplicationContext;public class Main {	public static void main(String[] args) {		// TODO Auto-generated method stub//		//		//      HelloWorld helloWorld=new HelloWorld();//      helloWorld.setName("wzc");//            //1.创建Spring 的IOC 容器对象		ApplicationContext ctx=new ClassPathXmlApplicationContext("appContext.xml");		//2.从IOC 容器中获取bean实例    //  HelloWorld helloWorld=(HelloWorld) ctx.getBean("helloWorld");          //3. 使用 bean     // helloWorld.hello();	}}helloWord代码：
package spring;public class HelloWorld {    private String name;    public HelloWorld() {		System.out.println("Hello wzc");	}    public void setName(String name) {    	System.out.println("setname"+name);		this.name = name;	}    public void hello() {	 System.out.println("hello"+name);    }}xml 文件代码：
