檢索Spring JPA事務異常的更多錯誤信息

Question

當我們嘗試保存對象和子對象時，我們遇到了一些奇怪的行爲和與事務不一致的地方。不幸的是，返回給我們的錯誤根本沒有幫助我們。我想知道是否有辦法獲得有關此例外的更多信息。我們正在分析我們的Model類和JPA註釋以確保所有內容都正確配置。這是目前正在從一個jUnit測試案例運行。在交易中保存對象時是否需要特別考慮？我們不想做任何特別的事情。我們正在創建一個Parent對象以及多個子對象，並試圖將其保存到數據庫中。當我們只是得到一個通用的「無法提交JPA」錯誤時，調試這個問題就很困難。任何幫助深表感謝。

Answer 1

您可以嘗試啓用sql trace並觀察執行的原始SQL。

Answer 2

我想你捕捉並忽略導致回滾某處的異常。檢查事務邊界內的代碼是否有被忽略的異常。

另一種可能性是事務明確標記爲回滾 - 僅通過調用EntityTransaction或TransactionStatus上的setRollbackOnly()。
