　　Jetty最常用的一种用法是把Jetty嵌入到自己的Java应用程序中，此时Jetty作为一个后台的Servlet容器运行，接受用户的http请求，下面是一个最简单的嵌入Jetty的用法。
　　1. 首先使用Maven创建一个java工程
mvn archetype:generate -DgroupId=com.google.code.garbagecan.jettystudy -DartifactId=jettystudy -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false2. 修改pom文件，添加或修改编译和依赖部分<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.google.code.garbagecan.jettystudy</groupId><artifactId>jettystudy</artifactId><packaging>jar</packaging><version>1.0-SNAPSHOT</version><name>jettystudy</name><url>http://maven.apache.org</url><build><plugins><plugin><artifactId>maven-compiler-plugin</artifactId><inherited>true</inherited><configuration><source>1.6</source><target>1.6</target><debug>true</debug></configuration></plugin></plugins></build><dependencies><dependency><groupId>org.eclipse.jetty.aggregate</groupId><artifactId>jetty-all</artifactId><version>8.0.4.v20111024</version><type>jar</type><scope>provided</scope></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency></dependencies></project>3. 创建一个Server类，用了启动Jetty server，并且通过一个HelloHandler来处理浏览器发送过来的请求；package com.google.code.garbagecan.jettystudy.sample1;import org.eclipse.jetty.server.Server;public class MyServer {public static void main(String[] args) throws Exception {Server server = new Server(8080);server.setHandler(new HelloHandler());server.start();server.join();}}4. 创建一个Handler类，用了处理所有客户端的请求package com.google.code.garbagecan.jettystudy.sample1;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>");response.getWriter().println("Request url: " + target);}}5. 运行MyServer类，然后通过浏览器访问http://localhost:8080/，可以看到“Hello World！”和请求的url。
