Question

首先，我想说我已经在我的案例中看到了stackoverflow的所有主题，但无论如何都无法解决我的问题。

我需要每晚运行预定的任务来检查任务完成的天气 - 我这样做：

@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并自动连接几个@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：

我无法弄清楚原因。另外如果我从@Controller启动相同的功能，它可以正常工作

@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可以从控制器中运行 - 按预期提交所有内容而不是按计划任务工作（通过所有进程而没有错误）？

Answer 1

如果可以，请在org.springframework.transaction.interceptor.TransactionAspectSupport.completeTra‌nsactionAfterThrowing(TransactionInfo txInfo, Throwable ex)中放置调试断点，然后查看实际异常是什么。

Answer 2

您不需要将CronBackGroundProcess标记为@Transactional，因为在StartNightJob()方法中，您无权访问数据库的所有访问权限，因为我猜您在CronJobService中执行。

从@Transactional移除CronBackGroundProcess，它必须有所帮助。

无法提交JPA事务 - RollbackException：标记为rollbackOnly
