zk使用的代码：

ExponentialBackoffRetry retryPolicy = new ExponentialBackoffRetry(zkConfig.getBaseSleepTimeMs(), zkConfig.getMaxRetries());
client = CuratorFrameworkFactory.newClient(zkConfig.getConnects(),zkConfig.getSessionTimeoutMs(),zkConfig.getConnectionTimeoutMs(),retryPolicy);
client.start();

解决方案

在启动代码里面加入zkClientConfig：

  ZKClientConfig zkClientConfig = new ZKClientConfig();zkClientConfig.setProperty(ZKClientConfig.ENABLE_CLIENT_SASL_KEY, "false");

 client =CuratorFrameworkFactory.newClient(zkConfig.getConnects(),zkConfig.getSessionTimeoutMs(),zkConfig.getConnectionTimeoutMs(),retryPolicy,zkClientConfig);
