Question

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 call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。如果我还需要客户端同样的响应实体

，我做错了什么

Answer 1

试试这个：

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

Answer 2

我不确定，但我认为它无法将“Success”字符串转换为ResponseEntity，而是使用字符串泛型类型：

@RequestMapping(value = "/v1/processfiles/", method = RequestMethod.POST)
public ResponseEntity<String> addProcessFiles(@RequestBody List<ProcessFiles> processFiles) {

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