jetty之建立多Connector

转自：http://blog.csdn.net/kongxx/article/details/7218787

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/。
