Question

当我们尝试保存对象和子对象时，我们遇到了一些奇怪的行为和与我们的事务不一致的问题。不幸的是，返回给我们的错误根本没有帮助我们。我想知道是否有办法获得有关此例外的更多信息。我们正在分析我们的Model类和JPA注释，以确保正确配置所有内容。目前正在从jUnit测试用例运行。在事务中保存对象时是否需要特别注意？我们不是要做任何特别的事情。我们正在创建一个Parent对象以及多个子对象，并尝试将其持久保存到数据库中。当我们刚刚获得通用的“无法提交JPA”错误时，很难调试该问题。非常感谢任何帮助。

Answer 1

您可以尝试启用sql跟踪并观察执行的原始SQL。

Answer 2

我认为你捕获并忽略了导致回滚的异常。检查事务边界内的代码是否有被忽略的异常。

另一种可能性是，通过在setRollbackOnly()或EntityTransaction上调用TransactionStatus，将交易明确标记为仅回滚。
