标记为仅回滚的事务:如何找到原因
2022-08-31 08:52:38
我在@Transactional方法中提交事务时遇到问题:
methodA() {
methodB()
}
@Transactional
methodB() {
...
em.persist();
...
em.flush();
log("OK");
}
当我从 methodA() 调用 methodB() 时,该方法成功通过,我可以在日志中看到“OK”。但后来我得到
Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Transaction marked as rollbackOnly org.springframework.transaction.TransactionSystemException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Transaction marked as rollbackOnly

- 方法B的上下文在异常中完全丢失 - 我想这是可以的吗?
- 方法 B() 中的某些内容将事务标记为仅回滚?我怎样才能找到它?例如,有没有一种方法可以检查类似的东西 - 像这样,我可以逐步完成该方法并找到原因。
