无法提交JPA事务 – RollbackException：事务标记为rollbackOnly

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 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，当所有事务必须提交时，我收到这样的错误：

我无法弄清楚为什么。 此外，如果我从@Controller启动相同的function，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

如果可以的话，在org.springframework.transaction.interceptor.TransactionAspectSupport.completeTra‌​nsactionAfterThrowing(TransactionInfo txInfo, Throwable ex)放置一个调试断点，然后看看实际的exception是什么。

Answer 2

您不需要将CronBackGroundProcess标记为@Transactional因为在StartNightJob()方法中您无法访问db对DB的所有访问权限，因为我猜您在CronJobService执行。

所以从CronBackGroundProcess删除@Transactional它必须有所帮助。
