Java 如何在Spring Boot中创建500错误的响应正文

我正在研究一个简单的Spring Boot项目，我想为500个错误创建一个响应对象.

这是控制器:

@RestController
@Slf4j
public class DataController {
    @PostMapping(value = "/data", consumes = "application/json", produces = "application/json")
    DataResponse createData(@RequestBody List<ClientRequest> completeRequest) throws Exception {
        log.info("completeRequest = {}", completeRequest);
        throw new Exception();
    }

误差

@Data
@Builder
@AllArgsConstructor
public class 误差DTO {
    private final String code;
    private final String message;
    private final String text;
}

异常处理程序:

@Slf4j
@ControllerAdvice
public class GlobalExceptionHandler {
    @ResponseBody
    @ExceptionHandler
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    public 误差DTO handleException(Exception exception) {
        log.error(exception.getMessage(), exception);
        return 误差DTO.builder()
                .code(HttpStatus.INTERNAL_SERVER_ERROR.getReasonPhrase())
                .message("Unexpected error!")
                .text("This is the text!")
                .build();
    }
}

When I call this API from Postman everything is fine and I get 500 Internal Server 误差 with response body:

{
    "code": "Internal Server 误差",
    "message": "Unexpected error!",
    "text": "This is the text!"
}

但问题是当我try 从另一个微服务调用此API时.我这样使用Rest模板:

try {
    ResponseEntity<ResponseDemo> result = restTemplate.postForEntity(uri, requestDemos, ResponseDemo.class);
    log.info("Success response: {}", result);
    ResponseDemo body = result.getBody();
    log.info("body= {}", body);
} catch (HttpClient误差Exception | HttpServer误差Exception ex) {
    log.error("ERROR at POST {}", ex.getMessage());
}

I receive only 500 Internal Server 误差, I can't find the Response Body

{
    "code": "Internal Server 误差",
    "message": "Unexpected error!",
    "text": "This is the text!"
}

有人能解释一下如何在其他服务中(而不仅仅在postman 中)接收响应机构吗？谢谢！
