Question

同样，同样的问题，但相关帖子中给出的其他答案对我没有帮助。

Maven格式的源代码位于：

https://github.com/jjYBdx4IL/my.bugs.smtpserver

git clone git@github.com:jjYBdx4IL/my.bugs.smtpserver.git

“mvn test”期间抛出异常：

知道我做错了吗？

Answer 1

您的交易方法storeEMail正由onMessage直接调用。事务行为由包装storeEMail的AOP代理实现。由于您直接调用storeEMail，因此不会调用AOP代理，也没有事务。需要在注入的bean引用上调用storeEMail。您可能想重新考虑您的设计。

Hibernate JPA和Spring javax.persistence.TransactionRequiredException：没有事务正在进行中（2）
