Spring4.3.3 WebSocket-STOMP协议集成 (2.1)-WebSocket-stomp子协议通讯小栗子

                      上一篇中说到：stomp - jsp之间的通讯，是通过stomp，socket.js/stomp.js实现的通讯。如果觉得写jsp或者js麻烦，或者不怎么会js,不是太懂，可以用webSocketStomp的client来测试。下面看代码：

                 pom.xml依赖：

	
	
    	org.glassfish.tyrus.bundles
    	tyrus-standalone-client
    	1.13
	

              JunitTest方法如下：具体和WebSocket的junit相似，不多解释了，老衲告退....

	/**

	 * @throws InterruptedException 
	 */
//	@Test

		//js url

		transports.add(new WebSocketTransport(new StandardWebSocketClient()));
		WebSocketClient transport = new SockJsClient(transports);
		//js endpoint end
		
		WebSocketStompClient stompClient  = new WebSocketStompClient(transport);
		
		stompClient.setMessageConverter(new StringMessageConverter());
