使用Solr 4.4時無法啟用Jetty壓縮

Question

我正在嘗試使用隨附的Jetty發行版運行Solr 4.4.0。 我希望在Jetty上啟用GZip壓縮，以減少網絡流量。 我正在嘗試運行分發中提供的默認“示例”。 我編輯了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，在啟動過程中，出現以下異常：

Solr服務器正在啟動，我也能夠正常查詢Solr。 但是結果並沒有變得混亂。 有人可以告訴我這里出了什么問題嗎？

Answer 1

我懷疑您需要將jetty-servlets工件添加到solr的啟動配置中。 我不知道Solr是如何啟動的，但是如果他們使用start.ini文件，那么您應該可以添加以下內容：

OPTIONS = jetty-servlet
