Jetty实战(2)之嵌入式运行Jetty多Connector

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/。
