java - 提交表单时出现 400 错误请求

Question

我似乎不明白为什么我不断收到 400 错误请求。在我收到 400 bad request 之前，表单有 "id" 而不是 "name"。当表单有 "id" 时，我得到了 200，但没有更新我的数据库。现在，我收到错误，但似乎没有任何效果。

这是我的 Controller :

@RequestMapping(value = "/registration", method = RequestMethod.POST)
public String registration(MemberVO vo, Model model) {
    System.out.println(vo);
   logger.info("regist post...");
   logger.info(vo.toString());

   try {

    mservice.insertMember(vo);


   } catch (Exception e) {

    e.printStackTrace();
   }
      return "/register_success";
}

@RequestMapping(value = "/registration", method = RequestMethod.GET)
public void registrationGet(MemberVO vo, Model model) {


}

这是我的表格:

  <form role = "form" method ="post">        

    <div class="form-group">
         <input type="email" class="form-control" name = "username" placeholder="Email"  required/>
         <span><i class="fa fa-envelope"></i></span>
    </div>

    <div class="form-group">
         <input type="password" class="form-control" name = "password" placeholder="Password"  required/>
         <span><i class="fa fa-lock"></i></span>
    </div>

    <div class="form-group">
         <input type="text" class="form-control" name = "firstname" placeholder="firstname"  required/>
         <span><i class="fa fa-user"></i></span>
    </div>

     <div class="form-group">
         <input type="text" class="form-control" name = "lastname" placeholder="lastname"  required/>
         <span><i class="fa fa-user"></i></span>
    </div>

    <div class="form-group">
         <input type="text" class="form-control" name = "phonenum" placeholder="Phone Number"  required/>
         <span><i class="fa fa-user"></i></span>
    </div>                                    

    <div class="form-group">
         <input type="text" class="form-control" name = "birthday" placeholder="Birthday, ex) 1986-06-08"  required/>
         <span><i class="fa fa-user"></i></span>
    </div>

    <div class="form-group">
         <input type="text" class="form-control" name = "destination" placeholder="where would you like to go?" required/>
         <span><i class="fa fa-user"></i></span>
    </div>

    <button type = "submit" class="btn btn-orange btn-block">Sign Up</button>
  </form>

Answer 1

我们无法告诉您确切的问题，因为您尚未附加模态类 MemberVO，但您可以在下面检查。

1.您的表单中没有操作属性。

2.确保 Modal 类中存在的所有字段也应以相同名称的形式出现。
