低级错误 先给自己两个大嘴巴子（好疼！！！）

按照官网配置好以后 一定 一定 一定要加配置

dubbo.config-center.timeout  这个参数值 可以写大一点 没关系

如果你的报错和我一样 并且出错位置如下 那就可以解决这个问题 

    public CuratorZookeeperClient(URL url) {
        super(url);
        try {
            int timeout = url.getParameter(TIMEOUT_KEY, DEFAULT_CONNECTION_TIMEOUT_MS);
            int sessionExpireMs = url.getParameter(ZK_SESSION_EXPIRE_KEY, DEFAULT_SESSION_TIMEOUT_MS);
            CuratorFrameworkFactory.Builder builder = CuratorFrameworkFactory.builder()
                    .connectString(url.getBackupAddress())
                    .retryPolicy(new RetryNTimes(1, 1000))
                    .connectionTimeoutMs(timeout)
                    .sessionTimeoutMs(sessionExpireMs);
            String authority = url.getAuthority();
            if (authority != null && authority.length() > 0) {
                builder = builder.authorization("digest", authority.getBytes());
            }
            client = builder.build();
            client.getConnectionStateListenable().addListener(new CuratorConnectionStateListener(url));
            client.start();
            boolean connected = client.blockUntilConnected(timeout, TimeUnit.MILLISECONDS);// 就是这里报错 timeout太小在默认3000之内没有链接上
            if (!connected) {
                throw new IllegalStateException("zookeeper not connected");
            }
        } catch (Exception e) {
            throw new IllegalStateException(e.getMessage(), e);
        }
    }
