如何在Jetty中启用gzip压缩？

我想知道如何在Broadleaf中为静态文件（js、css、html和图像）启用gzip压缩。我尝试了在项目的web.xml文件中添加以下内容，并且已经添加了与org.eclipse.jetty.servlets.GzipFilter类相对应的依赖:

<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，所以我要发布一个新问题。在我的项目中，我有一个名为jetty-web.xml的文件，内容如下：

<?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，出现了错误，说它不熟悉“filter”标签。 HTML/JS/CSS文件中是否需要添加或修改任何内容？

使用webdefault.xml中的init-param:

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

或者将处理程序添加到jetty.xml中：

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

<!-- If a GZIP handler is required for an individual context, then   -->
<!-- use a context XML (see test.xml example in distribution)        -->
