Spring MVC rest service with JSON content + multiple mutipart files

Question

Need a spring rest service which needs to take input as JSON content and Multiple mutipart files.

Answer 1

Below is the approach I followed to handle JSON content + multiple multiparts in spring MVC controller

BackEnd Implementation :

@RequestMapping(value = "/upload", method = RequestMethod.POST, consumes =    {"multipart/form-data"})
public
@ResponseBody
List<String> handleFileUpload(MultipartHttpServletRequest multipartHttpServletRequest) {
InputStream jsonSteam = multipartHttpServletRequest.getFile("json").getInputStream();
InputStream fileStream1 = multipartHttpServletRequest.getFile("file1").getInputStream();
InputStream fileStream2 = multipartHttpServletRequest.getFile("file2").getInputStream();
}

Front Implementation :

Request payload :

------WebKitFormBoundaryhKn3wrSAw57pRAso
Content-Disposition: form-data; name="file1"; filename="deleme_bkup.sql"
Content-Type: text/x-sql


------WebKitFormBoundaryhKn3wrSAw57pRAso
Content-Disposition: form-data; name="file2"; filename="source.sql"
Content-Type: text/x-sql


------WebKitFormBoundaryhKn3wrSAw57pRAso
Content-Disposition: form-data; name="json"; filename="blob"
Content-Type: application/json
