我创建了 java 应用程序,它使用消息驱动 bean(MDB) 通过 glassfish 中的资源适配器 activeMq 5.10 从主题 apache apollo 获取消息。当我使用 apache ActiveMQ 时,它可以正常工作,但不能与 apache apollo 一起使用。我使用 mqtt 发送带有主题 a 的消息,并使用 mqtt 来监听该主题并获取消息。但是当我使用 MDB 收听时,它无法收到任何消息。我看到 apollo 控制台,选项卡虚拟主机 -> 主题。我单击用于发送和接收消息的主题。该主题有消费者和生产者,“入队:2 个项目 / 2.72 kb”,但消费者“转移 = 0”。我不知道如何使用 Apollo 进行 MDB 工作。

发布消息的代码:
String user = env("APOLLO_USER", "admin");
String password = env("APOLLO_PASSWORD", "password");
String host = env("APOLLO_HOST", "192.168.0.54");
int port = Integer.parseInt(env("APOLLO_PORT", "7521"));
final String destination = arg(args, 0, "cuongdm17");
int messages = 1;
String body = "test";
MQTT mqtt = new MQTT();
mqtt.setHost(host, port);
mqtt.setUserName(user);
mqtt.setPassword(password);
FutureConnection connection = mqtt.futureConnection();
connection.connect().await();
final LinkedList<Future<Void>> queue = new LinkedList<Future<Void>>();
UTF8Buffer topic = new UTF8Buffer(destination);
for (int i = 1; i <= messages; i++) {
queue.add(connection.publish(topic, msg, QoS.AT_LEAST_ONCE, false));
