无法提交JPA事务 - RollbackException：标记为rollbackOnly的事务

Question

首先我想说我已经在我的案例中看到了所有的主题，但无法解决我的问题。

我需要每天晚上运行调度的任务，检查天气的任务是完成与否 - 我在做这样的：

@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@Transactional和autowires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.... 
      } 
     } 
    } 

过程不用错误，并在所有交易必须承诺我收到这样的错误：

我不明白为什么。 另外，如果我从@Controller推出相同的功能，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，为什么这个功能从控制器的工作原理 - 预期和计划任务未提交作品的一切（通过全过程不用错误）？

Answer 1

如果可以的话，请在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情况。

Answer 2

你不需要标记CronBackGroundProcess作为@Transactional，因为在StartNightJob()方法你没有访问数据库的所有访问数据库，因为我猜你在CronJobService执行。

因此请从CronBackGroundProcess删除@Transactional，它必须帮助。
