通过websocket客户端向服务器发消息时，报400错误

[baidu_27100831]

客户端代码

var webSocket = new WebSocket(
				'ws://127.0.0.1:8080/websocket');

		webSocket.onerror = function(event) {
			onError(event)
		};

		webSocket.onopen = function(event) {
			onOpen(event)
		};

		webSocket.onmessage = function(event) {
			onMessage(event)
		};

		function onMessage(event) {
			document.getElementById('messages').innerHTML += '<br />'
					+ event.data;
		}

		function onOpen(event) {
			document.getElementById('messages').innerHTML = 'Connection established';
		}

		function onError(event) {
			alert(event.data);
		}

		function start2() {
			webSocket.send('hello');
			return false;
		}

服务端代码：

import java.io.IOException;

import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;

@ServerEndpoint(value="/websocket")
public class WebSocketTest {

	@OnMessage
    public void onMessage(String message, Session session) 
    	throws IOException, InterruptedException {
		
		// Print the client message for testing purposes
		System.out.println("Received: " + message);
		
		// Send the first message to the client
		session.getBasicRemote().sendText("This is the first server message");
		
		// Send 3 messages to the client every 5 seconds
		int sentMessages = 0;
		while(sentMessages < 3){
			Thread.sleep(5000);
			session.getBasicRemote().
				sendText("This is an intermediate server message. Count: " 
					+ sentMessages);
			sentMessages++;
		}
		
		// Send a final message to the client
		session.getBasicRemote().sendText("This is the last server message");
    }
	
	@OnOpen
    public void onOpen () {
        System.out.println("Client connected");
    }

    @OnClose
    public void onClose () {
    	System.out.println("Connection closed");
    }
}

启动后报这个错误：
WebSocket connection to 'ws://127.0.0.1:8080/websocket' failed: Error during WebSocket handshake: Unexpected response code: 400
求解！！！！！！！！！！！！！！！！！！！！！！！！！！！

没人么？？？

wobsocket没人用额，当然没人帮你了 我只能提一些参考性建议 1.学习部署demo时不要修改内容，例如start2() 2.检查相关配置是否遗漏 3.查看错误信息提示以及处理方式，比如这个400错误，指的是语法错误，应该是“ws://127.0.0.1:8080/websocket”无法被解析

直接下载的demo，在本地跑起来也是会报400错误，本地环境是java8.0，tomcat8.0，配置没什么问题，不知道是不是jar包冲突，
