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");
			　　}
