I am trying to upload files and json object in single request. Basically, we have requirement that when user uploads the certificate it should not be stored in database or in file system. It should be immediately processed and discarded.
I created the API that would accept multipart/form-data.
Tried several methods to parse JSON object as String with @RequestParam, @RequestBody and wrapper
My Controller look like below snippet
@RequestMapping(value = "v2/loadbalancers", method = RequestMethod.POST)
@ApiOperation(value = "Create load balancer", notes = "Create load balancer", produces = MediaType.APPLICATION_JSON_VALUE)
@Authorized(rolesAllowed = {Roles.ALL})
public ResponseEntity<ResponseObject<LoadBalancerResponse>> submitCreateVipRequest(HttpServletRequest request,
@RequestParam(value = "lbRequest", required = false) String lbRequest,
@RequestParam(value = "cert", required = false) MultipartFile certificate,
@RequestParam(value = "key", required = false) MultipartFile key){
System.out.println("Debug line");
return null;
}
In Spring Controller, I am able to see the files but, json or string content is null. If I set
@RequestParam(value = "lbRequest", required = true) String lbRequest
Header in postman console look like
POST /cloudgateway/network/v2/loadbalancers
Authorization: eyJhbGciOiJIUzUxMiJ9......omitted

That throws missingservletrequestparameterexception - "Required String parameter 'lbRequest' is not present" I am using Postman form-data for testing and that has text type in key field.
My Problem is similar to MissingServletRequestParameterException
I tried several options like
Spring Controller @RequestBody with file upload is it possible?
