Question

我已将Jetty嵌入到我的应用程序中。我的要求很简单：使用HTTP / 2，禁用一些加密协议和密码，并使用我自己的处理程序来处理某些请求。我是从我的代码中做到的。它工作得很好。但现在我有客户想要使用Jetty中可用的更多HTTP功能，如基本身份验证或重定向。我不想在我的应用程序中添加越来越多的HTTP配置，所以我回到了Jetty XML配置文件的想法。

出于调试/监控的目的，我使用Server.dump()，我可以看到启用/禁用的密码或我的处理程序。是否可以基于工作Jetty或基于Jetty Server.dump()创建XML配置文件？

您不需要更改当前代码（更多）以开始使用XML来修改您的服务器。

考虑package org.eclipse.jetty.cookbook; import java.io.File; import java.net.URI; import java.net.URL; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import org.eclipse.jetty.server.HttpConfiguration; import org.eclipse.jetty.server.HttpConnectionFactory; import org.eclipse.jetty.server.Server; import org.eclipse.jetty.server.ServerConnector; import org.eclipse.jetty.server.handler.ContextHandlerCollection; import org.eclipse.jetty.server.handler.DefaultHandler; import org.eclipse.jetty.server.handler.HandlerList; import org.eclipse.jetty.servlet.DefaultServlet; import org.eclipse.jetty.servlet.ServletContextHandler; import org.eclipse.jetty.servlet.ServletHolder; import org.eclipse.jetty.util.resource.Resource; import org.eclipse.jetty.xml.XmlConfiguration; /** * This is a Server setup in a default way, but is can be enhanced by providing * (0 to n) Jetty XML file arguments on the command line. * * Run without a command line argument and pay attention to the contextPath for the * default Context.

时可用

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN"
  "http://www.eclipse.org/jetty/configure_9_3.dtd">
<Configure id="Context" class="org.eclipse.jetty.servlet.ServletContextHandler">
  <Set name="contextPath">/foobar</Set>
</Configure>

这将采用现有的嵌入式Jetty服务器，内部标记特定组件和ID Map，以及一些属性，以及用户提供的XML文件列表来配置此服务器。

以下是可以在此类设置中使用的一些XML。

调整 - 缺省 - contextpath.xml ：

<?xml version="1.0"?> <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd"> <Configure id="httpConfig" class="org.eclipse.jetty.server.HttpConfiguration"> <Set name="secureScheme">https</Set> <Set name="securePort">8443</Set> <Set name="outputBufferSize">32768</Set> <Set name="requestHeaderSize">8192</Set> <Set name="responseHeaderSize">8192</Set> <Set name="sendServerVersion">true</Set> </Configure>

<强>配置-http.xml ：

<?xml version="1.0"?> <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd"> <Configure id="Server" class="org.eclipse.jetty.server.Server"> <Call name="insertHandler"> <Arg> <New class="org.eclipse.jetty.rewrite.handler.RewriteHandler"> <Set name="rewriteRequestURI">true</Set> <Set name="rewritePathInfo">false</Set> <Set name="originalPathAttribute">requestedPath</Set> <Set name="dispatcherTypes"> <Array type="javax.servlet.DispatcherType"> <Item> <Call class="javax.servlet.DispatcherType" name="valueOf"> <Arg>REQUEST</Arg> </Call> </Item> <Item> <Call class="javax.servlet.DispatcherType" name="valueOf"> <Arg>ASYNC</Arg> </Call> </Item> </Array> </Set> <Get name="ruleContainer"> <Call name="addRule"> <Arg> <New class="org.eclipse.jetty.rewrite.handler.RedirectPatternRule"> <Set name="pattern">/bar/*</Set> <Set name="location">/foo</Set> </New> </Arg> </Call> </Get> </New> </Arg> </Call> </Configure>

添加-rewrites.xml ：
