带有标题和正文的 Spring RestTemplate POST 查询

Question

我需要使用给定的 API 定义，但我无法在 documentation 处找到同时接受 header 和请求正文的函数调用.请建议在这里使用 RestTemplate 的哪个功能。

@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);
