Java 执行器服务任务在spring boot应用程序中执行两次

我有一个Spring Boot应用程序，它当前有一个任务设置为每天运行并执行一个任务，但它看起来运行了两次，并导致了意外的副作用。该任务必须写入数据库，并且由于运行两次，我在数据库上得到一个错误

这个问题与部署有关，因为当我在本地运行它时，它可以正常工作。如果我在本地启动同一应用程序的另一个实例，我就能够模拟错误。这表明容器中的某些内容正在两次注册任务

 private void syncData(DatasetProperties dataset, EndPointSync lastSyncResult) {

    inProgressSyncs.addDataSet(dataset.getName());

    LocalDateTime currentSyncTime = LocalDateTime.now();
    DatasetSynchronizationResult currentSyncResult;
    Future<DatasetSynchronizationResult> resultFuture = datasetSynchronizationExecutorService
        .submit(getCallableForDataset(dataset, lastSyncResult, currentSyncTime));

    try {
      currentSyncResult = resultFuture.get();
    } catch (CancellationException | ExecutionException ex) {
      currentSyncResult = DatasetSynchronizationResult
          .unexpectedError(dataset.getName(), currentSyncTime);
      datasetSynchronizationLogger.logUnexpectedException(log, dataset, ex);
    } catch (InterruptedException ex) {
      currentSyncResult = DatasetSynchronizationResult
          .unexpectedError(dataset.getName(), currentSyncTime);
      datasetSynchronizationLogger.logUnexpectedException(log, dataset, ex);
      Thread.currentThread().interrupt();
    }

    inProgressSyncs.removeDataSet(dataset.getName());
    datasetSynchronizationLogger.logDatasetSynchronizationResult(
        log, lastSyncResult, currentSyncResult);
    updateSynchronizationResult(dataset, lastSyncResult, currentSyncResult);
  }

syncData方法是如何调度的？我正在使用接受参数的CronTrigger类。然而，我们在Spring boot中使用的格式是*0****，看起来格式实际上应该是0****。这可能会有所不同吗？
