如果要手工查看 可以这儿样

如果用代码访问 如下

## 使用授权模式获取节点数据 ##

@Test
        public void getDataWithAcl() throws KeeperException, InterruptedException { 
    
            String namePWD = "artisan:artisanPWD";
    
            // 对连接添加授权信息
            getZooKeeper().addAuthInfo("digest",namePWD.getBytes());
    
    
            byte[] data = getZooKeeper().getData("/artisanNode2", false, null);
    
            log.info("GET_DATA : {}",new String(data));
        }
    
    
        public static void main(String[] args) throws NoSuchAlgorithmException { 
            String sId = DigestAuthenticationProvider.generateDigest("artisan:artisanPWD");
            System.out.println(sId);
            // -Dzookeeper.DigestAuthenticationProvider.superDigest=artisan:d3gLrY2XgzvXZbJObw+wiWIQDko=
        }
