Question

我正在尝试在Jetty 9上启用gzip压缩。我不想在我的web.xml中配置它，因此基于Jetty文档我已经配置了override-web.xml。我不是在嵌入模式下使用Jetty，而是作为容器使用。

在我的{jetty.home}/webapps文件夹中，我有我的战争档案 - cc.war。我还定义了一个cc.xml如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">

<!-- ==================================================================
Configure and deploy the test web application in $(jetty.home)/webapps/test

Note. If this file did not exist or used a context path other that /test
then the default configuration of jetty.xml would discover the test
webapplication with a WebAppDeployer.  By specifying a context in this
directory, additional configuration may be specified and hot deployments
detected.
===================================================================== -->

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

  <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
  <!-- Required minimal context configuration :                        -->
  <!--  + contextPath                                                  -->
  <!--  + war OR resourceBase                                          -->
  <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
  <Set name="contextPath">/</Set>
  <Set name="war"><Property name="jetty.webapps"/>/cc.war</Set>

  <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
  <!-- Optional context configuration                                  -->
  <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
<!--   <Set name="extractWAR">true</Set>
  <Set name="copyWebDir">false</Set>
 -->
    <!--<Set name="defaultsDescriptor"><Property name="jetty.home" default="."/>/etc/webdefault.xml</Set>-->
  <Set name="overrideDescriptor"><Property name="jetty.webapps" default="."/>/cc.d/override-web.xml</Set>
</Configure>

在cc.d文件夹中，我覆盖了web.xml，如下所示：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app
        xmlns="http://xmlns.jcp.org/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_2_5.xsd"
        version="2.5">

    <filter>
        <filter-name>GzipFilter</filter-name>
        <filter-class>org.eclipse.jetty.servlets.GzipFilter</filter-class>
        <init-param>
            <param-name>methods</param-name>
            <param-value>GET,POST</param-value>
        </init-param>
        <init-param>
            <param-name>mimeTypes</param-name>
            <param-value>text/html,text/xml,text/plain,text/css,text/javascript,text/json,application/x-javascript,application/javascript,application/json,application/xml,application/xml+xhtml,image/svg+xml</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>GzipFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping> 
</web-app>

Jetty似乎加载这个很好，但gzip压缩不适用于任何响应。我说Jetty加载这个很好，因为早些时候当我试图将override-web.xml放在webapps文件夹中时，Jetty抱怨道。

我在这里经历了各种各样的问题，但他们似乎都没有答案。任何帮助表示赞赏。

Answer 1

我认为您应该能够在webdefault.xml中配置常用过滤器。尝试在那里注册Gzip过滤器。

Answer 2

在Jetty容器（非嵌入式）中运行时，将GZIP配置保留在应用程序之外的一种方法是将过滤器添加到上下文XML中：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
    <Set name="contextPath"><!-- set context path --></Set>
    <Set name="war"><!-- set war path --></Set>

    <Call name="addFilter">
        <Arg>org.eclipse.jetty.servlets.GzipFilter</Arg>
        <Arg>/*</Arg>
        <Arg>
            <Call name="of" class="java.util.EnumSet">
                <Arg><Get name="REQUEST" class="javax.servlet.DispatcherType" /></Arg>
            </Call>
        </Arg>
        <Call name="setInitParameter">
            <Arg>mimetypes</Arg>
            <Arg>text/html,text/xml,text/plain,text/css,text/javascript,text/json,application/x-javascript,application/javascript,application/json,application/xml,application/xml+xhtml,image/svg+xml</Arg>
        </Call>
        <Call name="setInitParameter">
            <Arg>methods</Arg>
            <Arg>GET,POST</Arg>
        </Call>
    </Call>
</Configure>
