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

- 异常中完全缺少methodB的上下文-我想这可以吗?
- methodB() 中的某些内容仅将事务标记为回滚?我怎样才能找到它?例如有没有办法检查类似的东西
getCurrentTransaction().isRollbackOnly()?
- 像这样我可以逐步检查方法并找到原因。
