org.springframework.http.converter.HttpMessageNotReadableException调用rest post call时

这是我的客户端代码

RestTemplate restTemplate = new RestTemplate();
    ResponseEntity responseEntity = restTemplate.postForObject(appConfig.getRestUrl(),processFiles, ResponseEntity.class);

这是我的Rest控制器代码：

@RequestMapping(value = "/v1/processfiles/", method = RequestMethod.POST)
public ResponseEntity addProcessFiles(@RequestBody List<ProcessFiles> processFiles) {
    try {
        processFilesDao.save(processFiles);
        return ResponseEntity.status(HttpStatus.OK).body("Success");
    } catch (Exception e) {
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body("Failure occured at server side");
    }

如果我在post调用中使用String.class作为返回类型，则相同的代码可以工作 . 但不能使用Response实体类 . 如果我需要客户端同样的响应实体，我做错了什么
