Question

我正在通过以下方法进行数据库调用：

@Transactional(rollbackFor = Exception.class, readOnly = false, propagation = Propagation.REQUIRES_NEW)
public void addLogEntry(LogEntry logEntry) throws FatalException
{
    mNonTxAlarmService = CONTEXT.getBean(NonTxAlarmService.class);
    JobExecution jobExecution = mNonTxAlarmService.getJobExecution(mJobExecution.getId());

    logEntry.setJobExecution(jobExecution);
    jobExecution.getLogEntries().add(logEntry);
}

其中mNonTxAlarmService.getJobExecution（）是一个服务调用，如下所示：

@Transactional(readOnly = true, propagation = Propagation.MANDATORY)
public JobExecution getJobExecution(Integer jobExecutionId)
    throws FatalException
{
    JobExecution jobExecution = mJobExecutionsService.get(jobExecutionId);
    return jobExecution;
}

当它被执行时，我得到以下异常 JobExecution jobExecution = mNonTxAlarmService.getJobExecution(mJobExecution.getId());：

org.springframework.transaction.IllegalTransactionStateException: No existing transaction found for transaction marked with propagation 'mandatory'

主调度员看起来像这样：

<mvc:annotation-driven />   
<tx:annotation-driven /> 
...     
<bean> id="importModule" class="com.xxx.yyy.zzz.aaa.ImportModuleImpl"></bean>

addLogEntry是ImportModuleImpl类中的一个方法。

我在哪里弄错了？
