請糾正這種

這是代碼，當我試圖運行此其顯示上面提到的錯誤，請幫我在這感謝ü所有

你是否在應用程序上下文中提到了hibernate.cfg.xml文件？ – LearningPhase

你還在哪裏放置了你的hibernate.cfg.xml文件？ – LearningPhase

當webapp啓動時，hibernate.cfg.xml必須位於類路徑的根目錄下。如果您使用maven構建項目，請將hibernate.cfg.xml放入src/main/resources目錄中，以便在構建war包時它將自動放置在/ WEB-INF/classes中。如果你不使用maven，把這個文件放在你的WEB-INF/classes目錄下。 – LearningPhase

移動你的hibernate.cfg.xml到目錄src/main/resources。這將解決問題
