springmvc的配置文件以下：目前配置的是：velocity+json

http://www.test.com/user.xml 呈現xml文件 css

http://www.test.com/user.json 呈現json格式 html

http://www.test.com/user 使用默認view呈現，好比jsp等 java

springmvc的Controller寫法： git

package com.demo.controller;

import com.demo.vo.User;
import com.wy.login.LoginSetvice;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import java.util.HashMap;
import java.util.Map;

@Controller
public class UserController {
    @Autowired
    private LoginSetvice loginSetvice;

    @RequestMapping(value = "index")
    public ModelAndView index(User user) {
        ModelAndView mav = new ModelAndView();
        mav.setViewName("index");
        return mav;
    }

    @RequestMapping(value = "vmIndex")
    public ModelAndView vmindex(User user) {
        com.wy.login.dto.User u = new com.wy.login.dto.User();
        BeanUtils.copyProperties(user, u);
        loginSetvice.insertUser(u);

        ModelAndView mav = new ModelAndView();
        mav.setViewName("indexShow");
        mav.addObject("user", user);
        mav.addObject("code", "0000");

        return mav;
    }


    @RequestMapping({"/test.html", "/test.json"})
    public ModelAndView test() {
        Map<String, String> map = new HashMap<String, String>();
        map.put("test", "json");
        map.put("test-html", "html");
        map.put("what", "what");
        ModelAndView modelAndView = new ModelAndView("/contentViewTest");
        modelAndView.addObject(map);
        return modelAndView;

    }
}
