Springboot - 无法捕获错误和请求超时

Question

我有一个控制器类

测试控制器.java

 @RequestMapping(value = "/{entityType}/values/timeseries", method = RequestMethod.GET, params = {...})
@ResponseBody
public DeferredResult<ResponseEntity> getGroupTimeseries(...) Boolean useStrictDataTypes) throws ThingsboardException {
    try {
        Futures.addCallback(tsService.findAll(tenantId, entityId, queries), new FutureCallback<List<TsKvEntry>>() {
            public void onSuccess(List<TsKvEntry> result) {
                Map<String, Object> volumeMap = fixedFlowRateAlgorithm(result, keys);
                // Additional processing
            }

            public void onFailure(Throwable thrown) {
                log.error("getGroupTimeseries" + thrown);
                deferredResult.setErrorResult(thrown);
            }
        }, MoreExecutors.directExecutor());
        return deferredResult;
    } catch (Exception error) {
        throw handleException(error);
    }
}

还有另一个静态方法

public static Map<String, Object> fixedFlowRateCalculate(...) {
  // No Side effect, pure method here
  // just calculation
  return results;
}

当我向此 API 端点发送请求时，运行一段时间后返回此错误

{
    "status": 500,
    "message": "Request timeout",
    "errorCode": 2,
    "timestamp": "2024-05-10T17:10:08.978+00:00"
}

但是，当我使用调试器跟踪问题时，错误实际上是

 ERROR c.g.c.util.concurrent.AbstractFuture - RuntimeException while executing runnable CallbackListener{org.thingsboard.server.controller.TestController$1@669c92f8} with executor MoreExecutors.directExecutor()

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "volume" (class org.thingsboard.server.data.SensorData), not marked as ignorable

为什么我无法获得 api 调用的错误响应？ 怎么解决？

我期待收到一条错误消息，指示

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException：无法识别的字段“卷”（org.thingsboard.server.data.SensorData 类），未标记为可忽略

通常，您不应该告诉客户端服务器上发生了 HTTP 500 错误的情况。这是违反安全的。如果您想知道发生了什么，请发送状态 200 并将错误消息添加到有效负载
