仅标记为回滚的事务:如何找到原因
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,并且可以在日志中看到“确定”。但后来我明白了
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 at org.springframework.orm.jpa.JpaTransactionManager.doCommit(JpaTransactionManager.java:521)

at methodA()...
- 在异常中完全缺少methodB的上下文-我想可以吗?
- methodB()中的某些内容将事务标记为仅回滚?我如何找到它?例如,有没有一种方法可以检查类似的东西
getCurrentTransaction().isRollbackOnly()?
-这样,我可以逐步检查方法并找到原因。
回答:
我终于明白了这个问题:
methodA() { methodB()
}
@Transactional(noRollbackFor = Exception.class)
methodB() {
...
try {
methodC()
} catch (...) {...}
log("OK");
}
@Transactional
methodC() {
throw new ...();
}
发生的是,即使methodB
的注释正确,methodC
但没有。引发异常后,第二个异常@Transactional
将第一个事务标记为“仅回滚”。
