java - 无法提交 JPA 事务 - RollbackException : Transaction marked as rollbackOnly

Question

首先我想说，我已经在 stackoverflow 上看到了针对我的案例的所有主题，但无论如何都无法解决我的问题。

我需要每天晚上运行计划任务来检查任务是否完成 - 我正在这样做:

@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 并 Autowiring 多个 @Transactional 服务

@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....
            }
        }
    }

该过程没有错误，当必须提交所有事务时，我收到这样的错误:

我不明白为什么。另外，如果我从 @Controller 启动相同的功能，它工作正常

@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";
    }
   }
}

所以我的问题是为什么这个函数在 Controller 中工作 - 按预期提交所有内容，而不是在计划任务中工作(无错误地完成所有过程)？

如果可以的话，在 org.springframework.transaction.interceptor.TransactionAspectSupport.completeTra‌​nsactionAfterThrowing(TransactionInfo txInfo, Throwable ex) 中放置一个调试断点然后查看实际的异常是什么。
