An http error 415 means that content of request is not in the appropriate format.
http 错误 415 表示请求的内容格式不正确。
Spring MVC '@RequestBody' expect a json body (with a Content-Type equal to 'application/json') and you explicitly set your Content-Type to undefined.
Spring MVC '@RequestBody' 需要一个 json 主体（Content-Type 等于 'application/json'），并且您将 Content-Type 显式设置为未定义。
The solution is to set your content-type to 'application/json' in your post request or to remove @RequestBody annotation.
解决方案是在您的发布请求中将您的内容类型设置为 'application/json' 或删除 @RequestBody 注释。
It seems that you try to upload files, the easier would be to remove @RequestBody annotation.
似乎您尝试上传文件，删除 @RequestBody 注释会更容易。

You should be sending multipart/form-dataand not undefinedvalue in your Content-Typeheader (Acceptheader sent from client should be application/json). Also make sure that the method on the server side consumes this particular media type.
您应该在您的标头中发送multipart/form-data而不是undefined值Content-Type（Accept从客户端发送的标头应该是application/json）。还要确保服务器端的方法使用这种特定的媒体类型。
