如何使用Jetty 9對動態內容啟用Gzip壓縮

[英]How to enable Gzip compression on dynamic content using Jetty 9

 原文  2013-06-19 09:34:23  8   2    solr/ jetty/ gzip

問題描述

我正在使用Jetty 9運行SolR。它工作正常。

我有以下配置：1個Web服務器（IIS），1個solr Server（Jetty）。

為了優化帶寬使用，我想在這兩個服務器之間啟用GZIP壓縮。

我試着將它添加到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>

我收到以下錯誤：

通常，您將GzipFilter添加到webapp的WEB-INF/web.xml並在您的WEB-INF/lib目錄中包含jetty-servlets.jar 。

但是，可以將它配置在頂級jetty服務器級別。

對於初學者，您獲得的錯誤表明您的服務器類路徑中不存在jetty-servlets.jar。

要對此進行測試，請從獨立的jetty-distribution中運行以下命令。 

$ java -jar start.jar --version

Active Options: [Server, annotations, client, ext, jaas, jmx, jndi, jndi.demo, jsp, plus, resources, rewrite, websocket]

這將顯示服務器類路徑，如您所見，標准分發默認情況下沒有jetty-servlets.jar 。 然而， start.config列入start.jar有一個預定義的OPTION為servlets

注意：要查看可運行的OPTIONS列表 

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

注意：要查看start.config的start.jar使用。 

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

最后，使用這些信息，我們可以簡單地使servlets OPTION通過編輯對碼頭的每次啟動可用start.ini 。 

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

$ java -jar start.jar --version
