当（杰克逊，在这种情况下）JSON引擎尝试解析一些未使用UTF-8编码的JSON时，会发生此错误。

如何告诉引擎它应该期望与UTF-8不同的东西，例如UTF-16？

HttpHeaders requestHeaders = createSomeHeader();
RestTemplate restTemplate = new RestTemplate();
HttpEntity<?> requestEntity = new HttpEntity<Object>(requestHeaders);
String url = "someurl"
ResponseEntity<MyObject[]> arrayResponseEntity = restTemplate.exchange(url, HttpMethod.GET, requestEntity, MyObject[].class);

错误日志：
