SpringMVC映射请求数据

1、获取超链接的参数和值

<a href="vote/vote01?name=love">获取超链接的参数</a>

  //获取超链接的参数
    @RequestMapping(value = "/vote01")
    public String vote01(@RequestParam(value = "name", required=false) String name){
        System.out.println("得到的userName"+name);
        return "voteOK";
    }

2、//获取请求头的参数

<hr><a href="vote/vote02">获取请求头参数</a>

//获取请求头的参数
    @RequestMapping(value = "/vote02")
    public String vote02(@RequestHeader("Accept-encoding") String ae){
        System.out.println("得到的http参数 = "+ae);
        return "voteOK";
    }

3、获取javaBean的数据 and 获取原生servlet api

<%--确保这里的name与bean的属性名一致，否则拿不到值--%>
<a>添加主人信息</a>
<form action="vote/vote04" method="post" >
    主人id：<input type="text" name="id"><br>
    主人名：<input type="text" name="monsterName"><br>
    宠物名：<input type="text" name="pet.petName"><br>
    <input type="submit" value="提交" ><br>
</form>

 //获取javaBean的数据 and 获取原生servlet api
    @RequestMapping(value = "/vote03")
    public String vote03(Monster monster, HttpServletRequest request,
                         HttpServletResponse response){
        System.out.println("得到的monster = "+monster);
        System.out.println("masterName = "+ request.getParameter("monsterName"));
        return "voteOK";
    }
