結果&問題

部署併發送請求「/test/tx.html」後，事務執行沒有問題，但數據庫記錄不會持久。 我想，交易沒有提交。 問題是什麼？

Answer 1

，我發現這個問題的原因。 事務聲明文件由DispatcherServlet加載時， 事務控制成功。 但是文件被ContextLoaderListener加載，事務控制不好。 我不知道爲什麼會出現這種差異。 你能向我解釋一下嗎？

Answer 2

豆用「AOP東西」裝飾BeanPostProcessor s（在你的情況下可能是AspectJAwareAdvisorAutoProxyCreator）。這些後處理器豆是上下文實例特定。

如果您在servlet上下文配置AOP，你必須在根上下文（反之亦然）目標豆，那麼這就是爲什麼不施加切入點。

通常的做法是具有較低級別的豆類（服務和DAO）與在根上下文 AOP配置在一起，並在servlet上下文只留下UI豆（MVC的東西）。
