SpringMVC:尝试 POST 重定向请求调用时抛出 415 不受支持的媒体类型

SpringMVC : Throws 415 Unsupported Media Type while attempting POST request call for redirection

浏览器响应如下:

服务器拒绝了此请求,因为请求实体的格式不受所请求方法所请求资源的支持。

而不是重定向到主页(home.jsp)

welcome.jsp 文件:

<form method ="POST" action = "<c:url value='/login'/>" >

       <input id="name" name="name" type="text">
       <input id="password" name="password" type="password">
       <input type="submit" id="loginNew" value="LoginNew"> 
  </form>

控制器class:

@RequestMapping( value="/login" , method = RequestMethod.POST )
    public ModelAndView authenticate ( @RequestBody User userObj ) throws Exception {
       ModelAndView modelAndView = new ModelAndView ();
        try {
            user = userService.authenticateUser ( userObj );
        } catch ( Exception e ) {
            e.printStackTrace();
         }
        modelAndView.setViewName("/home");
        return modelAndView;
    }

通过在方法参数中添加 @ModelAttribute 而不是 @RequestBody 解决了问题,然后按预期重定向到 home.jsp 页面。

@RequestMapping( value="/login" , method = RequestMethod.POST )
        public ModelAndView authenticate ( @ModelAttribute User userObj ) throws Exception {
           ModelAndView modelAndView = new ModelAndView ();
            try {
                user = userService.authenticateUser ( userObj );
            } catch ( Exception e ) {
                e.printStackTrace();
             }
            modelAndView.setViewName("/home");
            return modelAndView;
        }
