js使用WebSocket，java使用WebSocket

创建java服务端代码

				import java.net.InetSocketAddress;

				import org.java_websocket.WebSocket;

				import org.java_websocket.WebSocketImpl;

				import org.java_websocket.handshake.ClientHandshake;

				import org.java_websocket.server.WebSocketServer;

				public class MyWebSocket extends WebSocketServer{

					 public static void main(String[] args) {

							WebSocketImpl.DEBUG = false;

							int port = 8887; //端口

							MyWebSocket s = new MyWebSocket(port);

							s.start();

							System.out.println( "服务器的端口" + s.getPort() );

							}

					public MyWebSocket(int port){

						super(new InetSocketAddress(port));

					}

					public MyWebSocket(InetSocketAddress address) {

						super(address);

					}

				    /**

				     * 关闭时触发的事件

				     */

					@Override

					public void onClose(WebSocket arg0, int arg1, String arg2, boolean arg3) {

						// TODO Auto-generated method stub

					}

					/**

					 * 发生错误时

					 */

					@Override

					public void onError(WebSocket arg0, Exception arg1) {

						System.out.println(arg1);

					}

					/**

					 * 收到消息时

					 */

					@Override

					public void onMessage(WebSocket arg0, String arg1) {

						arg0.send("123");

						System.out.println(arg1);

					}

				    /**

				     * 打开连接时

				     */

					@Override

					public void onOpen(WebSocket arg0, ClientHandshake arg1) {

						System.out.println(1234455);

					}

				}

编写html页面代码

				if("WebSocket" in window){

			　　　　console.log("您的浏览器支持WebSocket");

					let a=new WebSocket(encodeURI('ws://127.0.0.1:8887'));

					a.onopen=function(){

						a.send("123aa");

					}

					a.onopen=function(){

						a.send("123aabbbb");

					}

					a.onmessage=function(msg){

						console.log(msg.data);

					}

			　　}else{

			　　　　console.log("您的浏览器不支持WebSocket");

			　　}
