Jetty多Connector
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：
view plaincopy
[*]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
view plaincopy
[*]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/。
public Connector[] getConnectors()
