代码实现

	
	@OnOpen
	public void open(Session session, @PathParam(value = "liveid") String liveid,
			@PathParam(value = "userid") String userid, @PathParam(value = "name") String name) {
		this.session = session;
		logger.error("进入   " + userid);
		
		
		socketServers.forEach(client -> {
			if (client.getUserid().equals(userid)) {
				try {
					logger.error("重复进入断开 " + userid);
					client.getSession().close();
					socketServers.remove(new Client(liveid, userid, name, session));
					socketServers.add(new Client(liveid, userid, name, session));
					return;
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
		});
		
		socketServers.add(new Client(liveid, userid, name, session));
		
		subscribeListener = new SubscribeListener();
		subscribeListener.setSession(session);
		subscribeListener.setUserid(userid);
		subscribeListener.setName(name);
		subscribeListener.setStringRedisTemplate(redisTampate);
		channeltopic=new ChannelTopic(liveid);
		
		//设置订阅topic
		redisMessageListenerContainer.addMessageListener(subscribeListener,channeltopic);
	}

 取消某个订阅

	if(subscribeListener!=null) {
				redisMessageListenerContainer.removeMessageListener(subscribeListener);
				subscribeListener=null;
			}
