Datastax Java driver 4.x :如何获取集群名称？

import com.datastax.oss.driver.api.core.CqlSession;
import com.datastax.oss.driver.api.core.metadata.Metadata;

public class ClusterNameExample {

    public static void main(String[] args) {
        // 创建CqlSession对象
        try (CqlSession session = CqlSession.builder().build()) {
            // 获取集群的元数据信息
            Metadata metadata = session.getMetadata();
            // 获取集群的名称
            String clusterName = metadata.getClusterName();
            System.out.println("Cluster Name: " + clusterName);
        }
    }
}
