小编leo*_*ges的帖子

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 methodA()...

1. 方法B的上下文在异常中完全丢失 - 我想这没关系？
2. methodB()中的某些内容将事务标记为仅回滚？我怎么能找到它？例如,有一种方法来检查类似的东西getCurrentTransaction().isRollbackOnly()?- 像这样我可以逐步完成方法并找到原因.

我的应用程序运行了几个月并且运行良好.然后我突然收到以下错误:

我在Google上发现一些问题,因为其他错误导致它关闭.但在我的情况下,没有任何.

它没有理由关机.

谁看过这个吗？

我正在使用Thymeleaf的Spring Boot,现在我想添加蒲公英数据表,但它不起作用.
