如何将提交的表单数据与multipartfile（image）一起传递，上传并将数据保存到controller end Spring MVC上的javabean

Question

My Html Content
<form role="form" name="frm1" action="http://localhost:8080/aricloud/rest/usermgmt/signup" id="signup" method="POST" enctype="multipart/form-data">

  <div class="form-group">`enter code here`
    <label for="username">Login Name</label>
    <input type="text" class="form-control" name="userName" id="username" placeholder="Enter Username" value="vindu525">
  </div>

  <div class="form-group">
    <label for="password">Password</label>
    <input type="password" class="form-control" name="password" id="passwd" placeholder="Password" value="12345">
  </div>

  <div class="form-group">
    <label for="confirm_password">Confirm Password</label>
    <input type="password" class="form-control" name="confirmPassword" id="confirmpasswd" placeholder="Please enter Password again" value="12345">
  </div>

  <div class="form-group">
    <label for="email">Email address</label>
    <input type="email" class="form-control" name="emailID" id="emailID" placeholder="Enter email" value="[e-mail]">
  </div>

  <div class="form-group">
    <label for="mobile">Mobile No</label>
    <input type="text" class="form-control" name="mobileNumber" id="mobileNumber" placeholder="Enter email" value="9584315174">
  </div>

  <div class="form-group">
    <label for="country">Country</label>
    <input type="text" class="form-control" name="country" id="country" placeholder="Enter country" value="india">
  </div>

  <div class="form-group">
    <label for="country">File Upload</label>
    <input type="file" class="form-control" name="image" id="image" >
  </div>

<input type="hidden" class="form-control"  name="userAvatar" id="userAvatar" value="null"/>

  <button id="regsubmit" type="submit" class="btn btn-default">Submit</button>
</form>

我的控制器

public ResponseEntity<String> addUser(@RequestBody UserDetailsBean user,
            @Context HttpServletRequest request,
            @Context HttpServletResponse response
            ) {
//File handling and other logic goes here 
}

当我发布数据时，我得到以下错误415（不支持的媒体类型）

虽然单独的文件和内容上传可以工作，但当我尝试将multipartfile与userdetails bean集成时，它会给我一个错误。

您可以为此使用MultipartHttpServletRequest

示例代码

@RequestMapping(value = "/url", method = RequestMethod.POST)
public String addNewProduct(MultipartHttpServletRequest request,
            @RequestParam String h) {
        String category = request.getParameter("parmname");
        //other stuff 
}
