Weblogic 10.3.6與自定義Servlet過濾器有關的問題

Question

我正在使用struts-hibernate項目，並且已成功部署在多個Web應用程序服務器中，例如Tomcat，JBoss，WAS等。

在WebLogic 10.3.6服務器中部署相同的應用程序時，這是一個奇怪的問題。

我在web.xml中沒有幾個過濾器來處理動作類之前的請求。 這些過濾器會在應用程序加載時進行初始化（調試會在init方法中進行），當我點擊URL時，它應該首先進入“我的過濾器類”的doFilter方法，但在使用weblogic的情況下，它將無法正常工作。

在其他Web應用程序服務器中也是如此。

在web.xml

我發現在擴展Filter類時，需要在filter類方法上方添加@Override批注。 添加此內容解決了我的問題。
