奇怪的例外

這是我的web.xml文件的工作版本：奇怪的例外

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
    version="2.5"> 

    <servlet> 
     <servlet-name>MainServlet</servlet-name> 
     <servlet-class>creator.controllers.MainController</servlet-class> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>MainServlet</servlet-name> 
     <url-pattern>/main</url-pattern> 
    </servlet-mapping> 

    <welcome-file-list> 
     <welcome-file>login.jspx</welcome-file> 
    </welcome-file-list> 
</web-app>

現在我想我的映射所有JSPX文件到這個servlet，使除非通過servlet才能訪問它們。

我加了以下幾行：

<servlet-mapping> 
    <servlet-name>MainServlet</servlet-name> 
    <url-pattern>*.jspx</url-pattern> 
</servlet-mapping>

...但我有一個例外，那就是不幸太長，在控制檯中完全顯示..

第一行的例外重複超過100次。現在我很無奈，因爲我不知道如何找出導致此問題的原因:(

這是不會飛。'servlet'試圖調用'jspx'，服務器將它重定向到'servl et'。您需要移動'jspx'並讓'servlet'使用未包含在映射中的重定向路徑。「過濾器」通常是攔截事物的更好選擇。 – BevynQ

ohh，我誤解了servlet映射..如果你願意，請從你的評論中作出回答，以便我可以將問題標記爲已解決:) 我的解決方案是將jspx文件放入WEB- INF文件夾，它們在默認情況下被保護以防止訪問。 – chris

該小服務程序試圖調用jspx，服務器將它重定向到該小服務程序，導致無限循環。

你將需要移動JSPX，並有該servlet使用不包含在映射重定向路徑。

的過濾器通常是截取的東西更好的選擇。
