Java code example: Here are a simple Java code example using Curator Framework to create Zookeeper nodes: import org.apache.curator.framework.CuratorFramework; import org.apache.curator.framework.CuratorFrameworkFactory; import org.apache.curator.retry.ExponentialBackoffRetry; public class CuratorExample { private static final String ZOOKEEPER_URL = "localhost:2181"; private static final String ZNODE_PATH = "/myNode"; public static void main(String[] args) throws Exception { CuratorFramework curatorFramework = CuratorFrameworkFactory.newClient(ZOOKEEPER_URL, new ExponentialBackoffRetry(1000, 3)); curatorFramework.start(); curatorFramework.create().creatingParentsIfNeeded().forPath(ZNODE_PATH, "Hello, Curator!".getBytes()); byte[] data = curatorFramework.getData().forPath(ZNODE_PATH); System.out.println(new String(data)); curatorFramework.close(); } } In the above example, we first created a CuratorFramework instance and configured the URL and retry strategy of the Zookeeper server.Then, we call the `start ()` method to start the CuratorFramework client and connect to the Zookeeper server.Next, we used the `Create ()" method to create a Zookeeper node and store some data.Finally, we read the data of the node with the method of `Getdata ()` and printed them.Finally, we call the `Close ()" method to close the CuratorFramework client. The above is a simple example, demonstrating how to use Curator Framework to interact with Zookeeper.In practical applications, you can use the rich features of Curator Framework to build more complex distributed applications.
