Question

我的项目从Quartz调度程序（版本2,2,0）执行基于Spring批处理（版本2.1.9）的任务我们正在一个多租户环境中工作，每个租户都在托管专用架构上维护自己的工作存储库。数据源植入是租户敏感的，每个租户的池连接。使用的事务管理器是org.springframework.jdbc.datasource.DataSourceTransactionManager

当我们执行调度程序时，任务成功执行。有一段时间我从春季批次中得到以下异常。请注意，其他任务也共享此调度程序。他们中的一些人有分配给他们的其他PlatformTransactionManagers。

2014-08-14 17:10:00,082 INFO [tenant_id] [org.quartz.core.JobRunShell] - <Job ROOT_GROUP. dataGenerator threw a JobExecutionException: >
org.quartz.JobExecutionException: java.lang.IllegalStateException: Existing transaction detected in JobRepository.
Please fix this and try again (e.g. remove @Transactional annotations from client).
[See nested exception: java.lang.IllegalStateException: Existing transaction detected in JobRepository.
Please fix this and try again (e.g. remove @Transactional annotations from client).]

使用@Transactional时我熟悉此异常（请参阅我的帖子here）。
但是，由于我的Job实际上是从调度程序运行的，并且作为一个独立的应用程序，这不是配置问题，因为偶尔会发生这种情况。我想在某个阶段，交易会以Spring Batch认为共享交易的方式延迟。或者在将线程返回到Quartz线程池之前，其他任务可能无法正确清除TransactionSynchronizationManager

<bean id="jobTransactionManager"
            class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="jobDataSource" />
</bean> 
<bean
    class="org.springframework.batch.core.configuration.support.JobRegistryBeanPostProcessor">
    <property name="jobRegistry" ref="jobRegistry" />
</bean>

<bean id="jobRepository" class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
    <property name="dataSource" ref="jobDataSource"/>
    <property name="databaseType" value="SQLSERVER"/>
    <property name="transactionManager" ref="jobTransactionManager"/>
</bean>

知道如何追查这个问题吗？请在下面找到完整的堆栈跟踪：
