solr - 如何使用 Jetty 9 对动态内容启用 Gzip 压缩

Question

我正在使用 Jetty 9 运行 SolR。它运行良好。

我有以下配置：1 个 Web 服务器（IIS），1 个 solr 服务器（Jetty）。

为了优化带宽使用，我想在这两个服务器之间启用 GZIP 压缩。

我试图将其添加到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>

我收到以下错误：

有人有想法吗？

Answer 1

通常，您将 GzipFilter 添加到您的 web 应用程序WEB-INF/web.xml并将其包含jetty-servlets.jar在您的WEB-INF/lib目录中。

但是，可以将其配置在顶级码头服务器级别。

对于初学者，您收到的错误表明您的服务器类路径中不存在 jetty-servlets.jar。

要对此进行测试，请从您的 jetty-distribution 独立运行以下命令。

$ java -jar start.jar --version

Active Options: [Server, annotations, client, ext, jaas, jmx, jndi, jndi.demo, jsp, plus, resources, rewrite, websocket]
Version Information on 36 entries in the classpath.

这将向您显示服务器类路径，如您所见，标准发行版jetty-servlets.jar默认情况下不可用。然而，start.config包含在其中的 start.jar有一个预定义OPTION的servlets

注意：要查看OPTIONS可用的列表，请运行

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

注意：查看start.config正在start.jar使用的。

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

最后，要使用这些信息，我们可以简单地servlets OPTION通过编辑start.ini.

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

$ java -jar start.jar --version

Answer 2

对于任何寻找帖子请求未压缩的答案的人；默认情况下，只有 GET 请求会被过滤器压缩。添加

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

压缩 POST。
