springMVC项目创建

结合maven一起使用，首先通过File-->new-->Maven Project创建maven项目，

点击Finish完成创建。

创建后目录结构如下：

pom.xml中存储的是maven依赖，从而导入相关jar包。

在src中建立如下目录结构：

pom.xml文件内容如下：

      contextConfigLocation
      classpath:spring/spring-mvc.xml
    
    1
  
  
    Dispatcher
    /
  
  
    index.jsp
  

spring-mvc.xml如下：

创建TestController.java如下：

package com.qc2.controllers;

import java.util.List;

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

import com.google.gson.Gson;

@Controller
public class TestContorller {
	@ResponseBody
    @RequestMapping(value ="views/hello", produces = "application/json;charset=utf-8",method ={RequestMethod.GET})
	public String hello(String age){        
        
        Gson gson =new Gson();
        String json =gson.toJson(age);
		return json;
    }
	
	
    @RequestMapping(value ="views/hello2", produces = "application/json;charset=utf-8",method ={RequestMethod.GET})
    public ModelAndView hello2(String name){ 
    	ModelAndView mv = new ModelAndView();
    	mv.addObject("message","ooooooooooooooo");
    	mv.setViewName("h2");
        return mv;
    }
}

创建Test.jsp如下：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

    









	ss

运行结果如下：
