Tomcat：自定義錯誤頁面不能正常工作

2012-07-25 41 views

那麼這應該已經夠簡單了。我修改了項目的web.xml，以顯示自己的錯誤頁500的：Tomcat：自定義錯誤頁面不能正常工作

<error-page> 
    <error-code>500</error-code> 
    <location>/error.jsp</location> 
</error-page>

然後我寫了簡單的servlet，以測試它：

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
{ 
    response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR); 
}

自定義頁面（這是位於根目錄）然後完全忽略，我得到默認的Tomcat錯誤頁面。

我正在使用MyEclipse調試器附帶的Tomcat 6版本。我翻了三倍 - 檢查了這個錯字，但我找不到任何不尋常的東西。我想知道錯誤頁面標籤是否需要位於文檔的某個部分。有誰知道會出現什麼問題？

你是什麼意思**我得到默認的Tomcat錯誤頁面，而不是** => 404頁面？ – mabbas 2012-07-25 20:02:36

+0

不是，它不是404，因爲「錯誤頁面未找到」，它是在我更改web.xml – JayPea 2012-07-25 20:06:05

之前顯示的常規500頁面，並且您的頁面error.jsp位於「webapp」文件夾的正下方？ – mabbas 2012-07-25 20:17:49

回答

response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);

將發出效應初探，HTTP狀態500這說明一個內部錯誤，但不會發出一個在你的應用程序。

嘗試

throw new ServletException();

代替，你會看到你的配置工作正常。

謝謝！就是這樣，我知道它必須是非常簡單的東西。看起來這個頁面是從當前URL打開的，因爲它沒有顯示CSS和圖片，但我想我只會使用絕對路徑。 – JayPea 2012-07-25 22:37:11

什麼是你的web.xml樣子？特別是servlet /過濾器映射？您可能需要將<dispatcher>ERROR</dispatcher>添加到您的servlet /過濾器映射中。

謝謝，讓我嘗試一下。我添加了上面的完整web.xml。 – JayPea 2012-07-25 20:11:01

+0

如果我不使用過濾器，這不適用？ – JayPea 2012-07-25 20:30:46

+0

我添加了一個過濾器來查看我是否可以手動重定向到我的錯誤頁面，但是* 錯誤 *也被忽略。如果我使用* 請求 *我可以讓過濾器運行，否則中斷點將永遠不會被擊中。這是你調查得越多，錯誤越少的錯誤之一。 – JayPea 2012-07-25 21:29:23

在servlet中，你應該叫：

response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);

相反的：

response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);

的setStatus用於設置返回的狀態代碼時沒有錯誤（例如， 爲狀態代碼SC_OK或SC_MOVED_TEMPORARILY）。如果出現錯誤，應該使用sendError方法。
