java - 当前请求不是多部分的

Question

我已经从 Swagger API 生成了一个 Spring REST Web 服务。 POST 服务的代码如下所示

@javax.annotation.Generated(value = "class io.swagger.codegen.languages.SpringCodegen", date = "2016-10-24T09:36:32.738Z")

@Api(value = "addUser", description = "the addUser API")
public interface AddUserApi {

@ApiOperation(value = "Add an additional user", notes = "This service is used to add and additional user to the list of users.", response = Void.class, tags={  })
@ApiResponses(value = { 
    @ApiResponse(code = 200, message = "OK", response = Void.class),
    @ApiResponse(code = 200, message = "Unexpected error", response = Void.class) })
@RequestMapping(value = "/addUser",
    produces = { "application/json" }, 
    consumes = { "application/x-www-form-urlencoded" },
    method = RequestMethod.POST)
ResponseEntity<Void> addUserPost(


@ApiParam(value = "Unique id of the user to be added.", required=true ) @RequestPart(value="userId", required=true)  Integer userId,


@ApiParam(value = "Name of the user to be added.", required=true ) @RequestPart(value="name", required=true)  String name,


@ApiParam(value = "Profession of the user to be added.", required=true ) @RequestPart(value="profession", required=true)  String profession);

}

我使用内容类型“application/x-www-form-urlencoded”将数据发布到此服务。但我面临的问题是，在发布时我收到一个错误的 JSON 作为响应，如下所示。

{
  "timestamp": 1477401894250,
  "status": 500,
  "error": "Internal Server Error",
  "exception": "org.springframework.web.multipart.MultipartException",
  "message": "The current request is not a multipart request",
  "path": "/UserManagement/rest/UserService/addUser"
}

据我所知，只有当我们从表单上传文件时才需要 multipart，我没有上传文件。我已经搜索过，每个结果都是基于文件上传的。下面给出了我的 swagger YAML。

有人可以帮助我并告诉我为什么我会遇到这个问题以及如何解决这个问题。如果您需要任何其他详细信息来分析问题，请告知。

请求头如下

{
  "Accept": "application/json"
}

已编辑:

我尝试将 consume 更改为“application/json”，我得到了如下所示的响应

{
  "timestamp": 1477464487595,
  "status": 415,
  "error": "Unsupported Media Type",
  "exception": "org.springframework.web.HttpMediaTypeNotSupportedException",
  "message": "Content type 'application/x-www-form-urlencoded' not supported",
  "path": "/UserManagement/rest/UserService/addUser"
}

请求头如下所示

{
  "Accept": "application/json"
}

您的映射包含 consumes = { "application/x-www-form-urlencoded"} 表示它接受二进制内容类型，将其更改为以下以接受 json 数据类型

@RequestMapping(value = "/addUser",
    produces = { "application/json" }, 
    consumes = { "application/json" },
    method = RequestMethod.POST)
ResponseEntity<Void> addUserPost(..)
