Spring RestTemplate POST Query with Headers and Body

Question

I need to consume the given API definition, But I am not able to find a function call that takes both headers and request body at documentation. Please suggest which function of RestTemplate to use here.

@RequestMapping(value = "/createObject", method = RequestMethod.POST,
        consumes = MediaType.APPLICATION_JSON_VALUE, 
        produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<CreateObjectOutput> createObject(
        @RequestBody CreateObjectInput req) 
{
    CreateObjectOutput out = new CreateObjectOutput();
    ///// Some Code
    return new ResponseEntity<CreateObjectOutput>(out, HttpStatus.OK);
}

Answer 1

RestTemplate template = new RestTemplate();
CreateObjectInput payload = new CreateObjectInput();

HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);

HttpEntity<CreateObjectOutput> requestEntity = 
     new HttpEntity<>(payload, headers);
CreateObjectOutput response = 
   template.exchange("url", HttpMethod.POST, requestEntity, 
              CreateObjectOutput.class);
