        model.addAttribute("name", "huangjie");

        //这个只有值没有键的情况下,使用Object的类型作为key,String-->string

        model.addAttribute("ok");

Two控制器

package ghy.webapp.myapp;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.bind.annotation.ResponseBody;

@Controller

public class TwoController {  

    @RequestMapping("login") //用来处理前台的login请求

    private @ResponseBody String hello(

            @RequestParam(value = "username", required = false)String username,

            @RequestParam(value = "password", required = false)String password

            ){

        return "Hello "+username+",Your password is: "+password;  

    }
