调用rest post调用时出现异常

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");
    }

如果我在调用后使用 String.class 作为返回类型，则相同的代码也有效。但不是响应实体类。我做错了什么，如果我需要客户端也相同的响应实体

Answer 1

我不确定，但我认为它不能将“成功”字符串转换为响应实体，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) {

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);
}
