在做Demo实例时，使用的jetty版本为8.x。为了避免麻烦，将所有的包都导入到MyEclipse的lib目录下。

实例1：自定义handler的服务器

package com.jetty.test01;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.eclipse.jetty.server.Request;import org.eclipse.jetty.server.handler.AbstractHandler;public class HelloHandler extends AbstractHandler{    public void handle(String target,Request baseRequest,HttpServletRequest request,HttpServletResponse response)         throws IOException, ServletException    {        response.setContentType("text/html;charset=utf-8");        response.setStatus(HttpServletResponse.SC_OK);        baseRequest.setHandled(true);        response.getWriter().println("<h1>Hello World</h1>");    }}

package com.jetty.test01;import org.eclipse.jetty.server.Server;public class SimplestServer{    public static void main(String[] args) throws Exception    {    Server server = new Server(8081);        server.setHandler(new HelloHandler());        server.start();        server.join();    }}

访问路径：http://localhost:8080

实例2：通过xml文件配置服务器

<?xml version="1.0"?><!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd"><Configure id="FileServer" class="org.eclipse.jetty.server.Server"><Call name="addConnector"><Arg><New class="org.eclipse.jetty.server.nio.SelectChannelConnector"><Set name="port">8080</Set></New></Arg></Call><Set name="handler"><New class="org.eclipse.jetty.server.handler.HandlerList"><Set name="handlers"><Array type="org.eclipse.jetty.server.Handler"><Item><New class="org.eclipse.jetty.server.handler.ResourceHandler"><Set name="directoriesListed">true</Set><Set name="welcomeFiles"><Array type="String"><Item>index.html</Item></Array></Set><Set name="resourceBase">.</Set></New></Item><Item><New class="org.eclipse.jetty.server.handler.DefaultHandler"></New></Item></Array></Set></New></Set></Configure>

package com.jetty.test01;import org.eclipse.jetty.server.Server;import org.eclipse.jetty.util.resource.Resource;import org.eclipse.jetty.xml.XmlConfiguration;public class FileServerXml {public static void main(String[] args) throws Exception{Resource fileserver_xml = Resource.newSystemResource("fileServer.xml");XmlConfiguration configuration = new XmlConfiguration(fileserver_xml.getInputStream());Server server = (Server)configuration.configure();server.start();server.join();}}

实例3：文件服务器：

package com.chinahrt.zyn.jetty;import org.eclipse.jetty.server.Handler;import org.eclipse.jetty.server.Server;import org.eclipse.jetty.server.handler.DefaultHandler;import org.eclipse.jetty.server.handler.HandlerList;import org.eclipse.jetty.server.handler.ResourceHandler;import org.eclipse.jetty.server.nio.SelectChannelConnector;public class FileServer {public static void main(String args[]) throws Exception{Server server = new Server();SelectChannelConnector connector = new SelectChannelConnector();connector.setPort(8080);server.addConnector(connector);ResourceHandler resource_handler = new ResourceHandler();resource_handler.setDirectoriesListed(true);resource_handler.setWelcomeFiles(new String[]{"index.html"});resource_handler.setResourceBase(".");HandlerList handlers = new HandlerList();handlers.setHandlers(new Handler[]{resource_handler,new DefaultHandler()});server.setHandler(handlers);server.start();server.join();}}

访问路径：http://localhost:8080

实例4：创建Servlet

package com.jetty.test01;import org.eclipse.jetty.server.Server;import org.eclipse.jetty.servlet.ServletContextHandler;import org.eclipse.jetty.servlet.ServletHolder;public class OneServletContext {public static void main(String[] args) throws Exception{Server server = new Server(8085);ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);context.setContextPath("/");server.setHandler(context);context.addServlet(new ServletHolder(new HelloServlet()), "/*");context.addServlet(new ServletHolder(new HelloServlet("Buongiorno Mondo")), "/it/*");context.addServlet(new ServletHolder(new HelloServlet("Bonjour le monde")), "/fr/*");server.start();server.join();}}

package com.jetty.test01;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class HelloServlet extends HttpServlet {private static final long serialVersionUID = 246698127519451952L;private String greeting="Hello World";public HelloServlet(){}public HelloServlet(String greeting){this.greeting = greeting;}protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException{response.setContentType("text/html");response.setStatus(HttpServletResponse.SC_OK);response.getWriter().println("<h1>"+greeting+"</h1>");response.getWriter().println("session="+request.getSession(true).getId());}}
