springmvc的配置：

action的代码：

package com.exercise.cn.action;


import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

import com.exercise.cn.entity.User;
import com.exercise.cn.biz.impl.IuserBiz;

public class HelloAction implements Controller{
	
	@Override
	public ModelAndView handleRequest(HttpServletRequest arg0,
			HttpServletResponse arg1) throws Exception {
		   //1、收集参数、验证参数  
	       //2、绑定参数到命令对象  
	       //3、将命令对象传入业务对象进行业务处理  
	       //4、选择下一个页面  
	       ModelAndView mv = new ModelAndView();  
	       //添加模型数据 可以是任意的POJO对象  
	       mv.addObject("message", "Hello World!");  
	       //设置逻辑视图名，视图解析器会根据该名字解析到具体的视图页面  
	       mv.setViewName("hello");  
	       System.out.println("hello");
	       return mv;  
	}
	
	public static void main(String[] args) {
		ApplicationContext ctx = new ClassPathXmlApplicationContext("spring/applicationContext.xml");
		IuserBiz b = (IuserBiz) ctx.getBean("userBiz");
		User user = new User();
		b.save(user);
	}

}

classpath*：spring/springMVC后面要带xml后缀。
