Transaction synchronization is not active问题

我遇到的是在使用异步进行操作时遇到的问题。

java.lang.IllegalStateException: Transaction synchronization is not active
	at org.springframework.transaction.support.TransactionSynchronizationManager.getSynchronizations(TransactionSynchronizationManager.java:306)
	at org.springframework.transaction.support.AbstractPlatformTransactionManager.triggerAfterCompletion(AbstractPlatformTransactionManager.java:969)

网上大多解决办法是看一下是不是调用异步这一方法的操作没有使用事务，添加@Transaction注解。

其实还有一个原因会引起。

可以查看一下这个异步是在controller层引用的还是service层引用的.在controller中引用的话不妨放到service中再试一下。
