//ServerEndpoint是websocket的必备注解, value是映射路径, configurator是配置类.
@ServerEndpoint(value = "/websocket", configurator=NutWsConfigurator.class)
@IocBean // 使用NutWsConfigurator的必备条件
public class GameWebsocket extends AbstractWsEndpoint {
	private static final Log log = Logs.get();
	@Inject JedisAgent jedisAgent;
	    public WsHandler createHandler(Session session, EndpointConfig config) {
	        GameWsHandler gamehandler = new GameWsHandler("GameRoom:");
	        WsRoomProvider  roomProvider = new JedisRoomProvider(jedisAgent);
	        gamehandler.setRoomProvider(roomProvider);
	        return gamehandler;
	    }

不知道是什么问题

具体哪一行的哪个变量为null

    public void join(String room, String wsid) {
        try (Jedis jedis = jedisAgent.getResource()) {
            jedis.sadd(room, wsid);
        }
    }

try (Jedis jedis = jedisAgent.getResource()) {这句

看看jedisAgent是不是null

jedisAgent不是null的,有这样一个错误

Caused by: redis.clients.jedis.exceptions.JedisDataException: ERR This instance has cluster support disabled

jedisAgent里面还有这样一个错误
jedisPool --->creationStackTrace
