如何安全删除RocketMQ消费者订阅组？

import org.apache.rocketmq.client.consumer.DefaultMQPushConsumer;
import org.apache.rocketmq.common.admin.MQAdminExt;
import org.apache.rocketmq.remoting.exception.RemotingException;

public class DeleteConsumerGroup {

    public static void main(String[] args) throws RemotingException, InterruptedException {
        // 创建默认消息推送消费者 (注意：此处consumer group name仅用于获取MQAdminExt，并非要删除的订阅组)
        DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("temp-consumer-group");
        consumer.start();

        // 获取MQAdminExt实例
        MQAdminExt mqAdminExt = (MQAdminExt) consumer.getDefaultMQPushConsumer().getMQAdminImpl();

        //  替换为您的订阅组名称
        String groupName = "your-subscription-group-name";

        // 删除订阅组
        mqAdminExt.deleteSubscriptionGroup(groupName);

        // 关闭消费者
        consumer.shutdown();
        System.out.println("订阅组 '" + groupName + "' 删除成功!");
    }
}
