無法提交JPA事務-RollbackException：事務標記為rollbackOnly

Question

首先，我想說的是，我在這里看到了關於stackoverflow的所有主題，但是仍然無法解決我的問題。

我需要每天晚上運行排定的任務，以檢查任務是否完成-天氣情況如下：

@Service
@Transactional
public class CronBackGroundProcess {

@Autowired
private CronJobService cronJobService;

@Scheduled(cron = "15 01 01 ? * *")
public void StartNightJob() {
    CronJobLog log = new CronJobLog();
    int count = 0;
    try {
        log.setStartTime(new Date());
        log.setStatus("Entered StartNightJob Function");
        cronJobService.saveCronJobLog(log);

        List<Task> Tasks = cronJobService.getActive_AND_InArreasTasks();
        log.setStatus("Grabbed List of tasks to Check");
        cronJobService.saveCronJobLog(log);

        for (Task Task : Tasks) {
            cronJobService.StartNightJobProcess(Task, true);
            count++;
        }
    } catch (Exception e) {
        CronJobLog log2 = new CronJobLog();
        log2.setStatus("Error Occurred " + new Date().toString() + e.getMessage());
        cronJobService.saveCronJobLog(log2);
    }

    log.setLoansChecked(count);
    log.setStatus("Finished");
    log.setEndDate(new Date());
    cronJobService.saveCronJobLog(log);
}
}

CronJobService本身是@Transactional並自動關聯幾個@Transactional服務

@Service
@Transactional
public class CronJobService {

@Autowired
private ProductService productService;

@Autowired
private RepaymentService repaymentService;

@Autowired
private CronJobLogDAO cronJobLogDAO;


@Autowired
private TransferService transferService;

public String StartNightJobProcess(Account account, boolean makeTransfers) {

    do something....
            }
        }
    }

該過程沒有錯誤，當必須執行所有事務時，我會收到這樣的錯誤：

我不知道為什么。 另外，如果我從@Controller啟動相同的功能，則效果很好

@Controller
@RequestMapping("/test")
public class test {

@Autowired
private ClientService clientService;

@Autowired
private CronBackGroundProcess cronBackGroundProcess;

@RequestMapping(value = "/test")
@ResponseBody
public void test() throws Exception {
    try {

        cronBackGroundProcess.StartNightJob();
    } catch (Exception e) {
       String s = "sd";
    }
   }
}

所以我的問題是，為什么此功能可從控制器工作-像預期的那樣提交所有內容，而不能從計划的任務中工作（經過所有過程而沒有錯誤）？

Answer 1

如果可以的話，將調試斷點放在org.springframework.transaction.interceptor.TransactionAspectSupport.completeTra‌​nsactionAfterThrowing(TransactionInfo txInfo, Throwable ex) ，然后查看實際的異常是什么。

Answer 2

您不需要將CronBackGroundProcess標記為@Transactional因為在StartNightJob()方法中，您無權訪問db的所有數據庫，因為我猜您在CronJobService執行。

因此，從CronBackGroundProcess刪除@Transactional ，它必須有所幫助。
