在ActiveMQ Artemis 2.17.0版本中，TopicControl listAllSubscriptions方法的新功能允许返回订阅者的完整信息，包括订阅者ID、客户端ID、协议等等。

代码示例如下：

try (ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url)) { Connection connection = connectionFactory.createConnection(); connection.start(); ActiveMQTopicControl topicControl = new ActiveMQTopicControl(connection); SubscriptionInfo[] subscriptionInfos = topicControl.listAllSubscriptions(); for (SubscriptionInfo subscriptionInfo : subscriptionInfos) { System.out.println("Subscription ID: " + subscriptionInfo.getSubscriptionID()); System.out.println("Client ID: " + subscriptionInfo.getClientID()); System.out.println("Protocol: " + subscriptionInfo.getProtocol()); System.out.println("Filter: " + subscriptionInfo.getFilterString()); System.out.println("Routing Name: " + subscriptionInfo.getRoutingName()); } } catch (Exception e) { e.printStackTrace(); }

使用上述代码示例，我们可以遍历所有订阅该特定主题的订阅者，并获取完整的订阅者信息。
