自定义 Servlet 过滤器的 Weblogic 10.3.6 问题
Weblogic 10.3.6 Issue with Custom Servlet Filters
我正在使用 struts-hibernate 项目并成功部署在多个 Web 应用程序服务器中，例如 Tomcat、JBoss、WAS 等
这是我在 WebLogic 10.3.6 服务器中部署相同应用程序时遇到的一些奇怪问题。
我在 web.xml 中有几个过滤器用于在操作 类 之前处理请求。这些过滤器在应用程序加载时初始化（调试进入 init 方法），当我点击 URL 时，它应该首先进入我的过滤器的 doFilter 方法 类，但在 weblogic 的情况下它不起作用。
在其他 Web 应用程序服务器中同样适用。
