WebSocket Error during WebSocket handshake: Unexpected response code: 200

首先明确，出现200说明服务器的webSocketServer已经收到了请求

	public boolean beforeHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandlerwsHandler,Map<String, Object> attributes) throws Exception {
		System.out.println("连接前");
		return false;
	}

我的问题出在 beforeHandshake 方法return了false，改为ture则可，因为内代码是生成的，新手应该很容易踩到这个坑
