@skyjilygao 就是在 ZK 上创建一个节点 `/dubbo/config/dubbo/dubbo.properties `, 并设置其内容为:

```
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.metadata-report.address=zookeeper://127.0.0.1:2181
```

项目第一次启动调试的时候, 如果 ZK 没有这个配置, 会看不到元数据, 可以在 
`org.apache.dubbo.admin.config.ConfigCenter` 中添加以下代码来创建这个节点(也可以通过其他方式):

```java


    @PostConstruct
    public void init() throws Exception {
        CuratorFramework zkClient = CuratorFrameworkFactory.builder().
                connectString("127.0.0.1:2181").
                retryPolicy(new ExponentialBackoffRetry(1000, 3)).build();
        zkClient.start();

        if 
(zkClient.checkExists().forPath("/dubbo/config/dubbo/dubbo.properties") == 
null) {
            
zkClient.create().creatingParentsIfNeeded().forPath("/dubbo/config/dubbo/dubbo.properties");
        }
        zkClient.setData().forPath("/dubbo/config/dubbo/dubbo.properties", 
("dubbo.registry.address=zookeeper://127.0.0.1:2181\n" +
                
"dubbo.metadata-report.address=zookeeper://127.0.0.1:2181").getBytes());
    }
```

类似这样:
