在嵌入运行Jetty的时候，有时候想要启动两个端口，或者通过一个Jetty server提供多个不同服务，比如说使用8080来指定默认访问端口，使用8433指定https访问端口等等，此时就可以通过创建多个Connector来解决。

1. 首先创建一个Server类，其中创建了两个Connector实例，一个绑定到了8080端口，另一个绑定到了9090端口：

package com.google.code.garbagecan.jettystudy.sample2;  import org.eclipse.jetty.server.Connector; import org.eclipse.jetty.server.Server; import org.eclipse.jetty.server.nio.SelectChannelConnector;  public class MyServer {  public static void main(String[] args) throws Exception {   Server server = new Server();    SelectChannelConnector connector1 = new SelectChannelConnector();   connector1.setPort(8080);    SelectChannelConnector connector2 = new SelectChannelConnector();   connector2.setPort(9090);    server.setConnectors(new Connector[] { connector1, connector2 });    server.setHandler(new HelloHandler());    server.start();   server.join();  } }

2. 创建一个Handler类，用了处理所有客户端的请求

package com.google.code.garbagecan.jettystudy.sample2;  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("<li>Request url: " + target + "</li>");   response.getWriter().println("<li>Server port: " + request.getServerPort() + "</li>");  } }

3. 运行MyServer类，通过浏览器分别访问http://localhost:8080/和http://localhost:9090/。
