使用 Solr 4.4 时无法启用 Jetty 压缩

【问题标题】：Unable to enable Jetty compression while using Solr 4.4使用 Solr 4.4 时无法启用 Jetty 压缩
【发布时间】：2013-11-08 00:25:18
【问题描述】：

我正在尝试使用随附的 Jetty 发行版运行 Solr 4.4.0。我希望在 Jetty 上启用 GZip 压缩以减少网络流量。我正在尝试运行分发中提供的默认“示例”。我编辑了 example/solr-webapp/webapp/WEB-INF/web.xml 文件以在下面添加以下行：

<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,image/svg+xml</param-value>
</init-param>
</filter>
<filter-mapping>
  <filter-name>GzipFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

但是，在启动过程中，我收到以下异常：

Solr 服务器正在启动，我也可以正常查询 Solr。但结果并没有得到 gzip 压缩。谁能告诉我这里出了什么问题？

【问题讨论】：

    标签： exception solr jetty gzip


    【解决方案1】：

    我怀疑您需要将 jetty-servlets 工件添加到 solr 的启动配置中。我不知道 Solr 是如何启动的，但如果他们使用 start.ini 文件，那么您应该能够添加类似的内容：

    OPTIONS=jetty-servlets

    【讨论】：

    • Solr with jetty 确实使用了嵌入在 start.jar 中的 start.config 文件。显然我使用的发行版缺少 jetty-servlets-.jar 文件。下载文件并将其复制到 ${jetty.home}/lib 即可解决问题。
    • 是的，自定义 solr 发行版......我们对此无能为力
