【问题描述】：

我想知道如何为 Broadleaf 中的静态文件（js、css、html 和图像）启用 gzip 压缩。我在项目的 web.xml 文件中尝试了以下内容，并且还获得了与 org.eclipse.jetty.servlets.GzipFilter 类对应的依赖项：

<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>

我在 Stack Overflow 上看到的问题没有给我答案，所以我发布一个新问题。在我的项目中，我有一个像这样的 jetty-web.xml：

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

    <Set name="contextPath">/</Set>

</Configure>

当我尝试在 jetty-web.xml 文件中添加 filter mappings 时，我收到一个错误，它不熟悉 过滤标签。

我应该在 HTML/JS/CSS 文件中添加/修改什么吗？

【参考方案1】：

在webdefault.xml 中使用init-param：

<init-param>
  <param-name>gzip</param-name>
  <param-value>true</param-value>
</init-param>

或将处理程序添加到jetty.xml：

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd">
