RestClientException：无法写入请求：找不到适合请求类型 [xxx.query.XBrainQueryRequest] 和内容类型 [application/json] 的 HttpMessageConverter。

XBrainQueryRequest request = new XBrainQueryRequest();
// set query ID

request.setFlags(new String[]{"ALL_FIELDS"});

logger.info("calling XBrainTradeQuery and  Input:{}",objectMapper.writeValueAsString(request));

HttpHeaders headers = new HttpHeaders();

headers.setContentType(MediaType.APPLICATION_JSON);

 try
       {
       restTemplate = new RestTemplate();

       ResponseEntity<XBrainTradeList> result=null;
       xBrainTradeList =null;

       ResponseEntity<XBrainTradeList> result1 = restTemplate.exchange(XBrainTradeQueryURL, HttpMethod.POST, new HttpEntity(request, headers), XBrainTradeList.class);

我的 XBrainQueryRequest 类如下

@JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL)
public class XBrainQueryRequest {

    private String queryId;
    private String[] flags;
    private String[] attributes;
