强制Spring / JPA / Hibernate / JDBC重试失败的beginTransaction？
|
有时，由于尝试到达MySQL时会发生简单的SocketException，因此无法开始数据库事务。在当前代码库中，所有SQL或JPQL代码都位于带有@Transactional批注（org.springframework.transaction.annotation）的类中。对于为带注释的类的每个方法调用，都会为我创建一个事务。这使得很难编写可在所有数据库调用之间重用的代码。
一种解决方案是将db代码放在一个循环中：它将重试该事务几次。这行得通，但我不想让代码充满循环（每个数据库调用一个）。
他们是否有办法使以下任一框架自动重试失败的beginTransaction ？： Spring，JPA，Hibernate，c3p0，MySQL JDBC驱动程序
供参考，以下是部分日志：
