Controller

package com.monkey1024.controller;

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

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;


/*
 * 使用注解后就不需要实现接口了
 */
@Controller//表示当前类是一个controller
@RequestMapping("/test")//表示是一个命名空间namespace,抽取出重复的部分
public class HelloSpringMVC  {
	
	
	// 需要处理的url
//	@RequestMapping("/test/test2.do")
	@RequestMapping("/test2.do")
	// 方法名可以随意命名
	public ModelAndView test1(HttpServletRequest request, HttpServletResponse response) throws Exception {
		ModelAndView mv = new ModelAndView();
		// 类似键值对
		mv.addObject("hello","test2");
		// 连接到jsp
		mv.setViewName("first");
		return mv;
		
		
		
	}
	/*
	 * 以数组的形式，下面两个都可以调用这个方法
	 */
//	@RequestMapping({"/test/hello.do","/test/world.do"})
	@RequestMapping({"/hello.do","/world.do"})
	
	public ModelAndView test2(HttpServletRequest request, HttpServletResponse response) throws Exception {
		ModelAndView mv = new ModelAndView();
		// 类似键值对
		mv.addObject("hello","helloworld");
		// 连接到jsp
		mv.setViewName("first");
		return mv;
