如何使用Jetty在動態內容上啓用Gzip壓縮9

我使用Jetty 9運行SolR。它工作正常。如何使用Jetty在動態內容上啓用Gzip壓縮9

我有以下配置：1個Web服務器（IIS），1個Solr的服務器（碼頭）。

爲了優化帶寬的使用，我想使本2個服務器之間GZIP壓縮。

我試圖加入到這個jetty/etc/webdefault.xml：

<filter> 
    <filter-name>GzipFilter</filter-name> 
    <filter-class>org.eclipse.jetty.servlets.GzipFilter</filter-class> 
    <init-param> 
     <param-name>mimeTypes</param-name> 
     <param-value>text/html,text/plain,text/xml,application/xhtml+xml,text/css,application/javascript,application/json,image/svg+xml</param-value> 
    </init-param> 
</filter> 
<filter-mapping> 
    <filter-name>GzipFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
</filter-mapping>

我得到以下錯誤：

通常，您將GzipFilter添加到您的Web應用程序的WEB-INF/web.xml，並將jetty-servlets.jar包含在您的WEB-INF/lib目錄中。

然而，有可能把它在頂層碼頭服務器級別配置。

對於初學者來說，你所得到的錯誤指示碼頭 - servlets.jar不存在於您的服務器類路徑。

要測試此操作，請從您的jetty-distribution獨立版運行以下代碼。

$ java -jar start.jar --version

這將顯示您的服務器類路徑中，你可以看到，標準的分佈沒有jetty-servlets.jar默認情況下可用。然而列入start.jar的start.config有一個預定義OPTION爲servlets

注意：要查看的OPTIONS列表，運行

$ java -jar start.jar --list-options

需要注意的是：若要看到start.jar使用start.config。

$ java -jar start.jar --list-config

最後，使用這些信息，我們可以簡單地通過編輯start.ini使可在碼頭的每一次啓動servletsOPTION。

$ echo "OPTIONS=servlets" >> start.ini 

$ java -jar start.jar --version

嗨。 謝謝你的回答，非常詳細。知道，我明白它是如何工作的。 jetty-servlets.jar現在已成功加載，並且沒有例外。 但我仍然有一個問題：我嘗試請求SolR（POST請求，使用Accept-Encoding：gzip，deflate）但響應沒有被壓縮。我嘗試將application/xml添加到webdefault.xml中，但它不起作用（我使用Fiddler）。 你有任何想法如何調試它？ 非常感謝 – heisenberg

@heisenberg我有同樣的問題 - 最終爲你做了這個工作嗎？即使GET請求，GZIP也不適用於我。我已經在override-web.xml中設置了過濾器。 – IceMan

@IceMan只是將它添加到override-web.xml對於jetty或您的webapp來說並不足以使用它。您可部署的上下文還應引用override-web.xml作爲其覆蓋。 –

爲尋找爲什麼POST請求沒有壓縮的答案;默認情況下，只有GET請求被過濾器壓縮。添加

<init-param> 
     <param-name>methods</param-name> 
     <param-value>GET,POST</param-value> 
    </init-param>

壓縮POST。
