Jetty实战之 嵌入式运行Jetty多Connector

13年前
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/。
