ActiveMQ Artemis 2.10.1 + JMS 2.0 - 共享訂閱不起作用

Question

軟件：

• 阿帕奇阿爾忒彌斯 2.10.1
• TomEE plus 8.0

我創建了一個有 2 個消費者的主題。 每個消費者都有 1 個 MDB。 我有一個主要的方法來進行配置和所有操作。

即使我只發送一條消息並指定這是一個共享訂閱，該消息也被兩個 MDB 使用。 不知道如何解決這個問題。 當然沒有錯誤。 但這不是我的代碼預期的功能。

@MessageDriven(name = "TOPICMDB1", activationConfig = { 
    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
    @ActivationConfigProperty(propertyName = "destination", propertyValue = "BTOPIC"),
    @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
    @ActivationConfigProperty(propertyName = "subscriptionName", propertyValue = "mytopic"),
    @ActivationConfigProperty(propertyName = "subscriptionDurability", propertyValue = "durable"),
    @ActivationConfigProperty(propertyName = "shareSubscriptions", propertyValue="true"),
    @ActivationConfigProperty(propertyName = "clientId", propertyValue = "MyClientId_1")
})

@MessageDriven(name = "TOPICMDB2", activationConfig = {
    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
    @ActivationConfigProperty(propertyName = "destination", propertyValue = "CTOPIC"),
    @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"), 
    @ActivationConfigProperty(propertyName = "subscriptionName", propertyValue = "mytopic"),
    @ActivationConfigProperty(propertyName = "subscriptionDurability", propertyValue = "durable"),
    @ActivationConfigProperty(propertyName = "shareSubscriptions", propertyValue="true"),
    @ActivationConfigProperty(propertyName = "clientId", propertyValue = "MyClientId_2")
})      

connectionFactory = new ActiveMQConnectionFactory(input.getUrl());
connection = (ActiveMQConnection) connectionFactory.createConnection(input.getUsername(), input.getPassword());
session = connection.createTopicSession(input.isTransacted(), Session.AUTO_ACKNOWLEDGE);
connection.start();
session = connection.createTopicSession(true, Session.SESSION_TRANSACTED);  
destination = session.createTopic("ATOPIC");
consumer = session.createSharedDurableConsumer( (Topic) destination, "mytopic");
rtn = consumer.receive();
session.commit(); 

我不確定為什么要在mytopic （訂閱名稱）上創建這個共享的持久消費者。 我正在嘗試所有不同的方法來完成我的任務。

tomee.xml :

<Resource id="ATOPIC"
          class-name="org.apache.activemq.artemis.api.jms.ActiveMQJMSClient"
          constructor="name"
          factory-name="createTopic"
          type="javax.jms.Topic">
   name=ATOPIC
</Resource>

broker.xml ：

<address name = "ATOPIC">
   <multicast>
      <queue name = "BTOPIC"/>
      <queue name = "CTOPIC"/>
   </multicast>
</address>

Answer 1

您的配置在多個地方不正確。

首先，JMS 主題由支持multicast的address實現，僅此而已。 這在ActiveMQ Artemis 文檔中有說明。 因此，您的broker.xml應該具有以下內容：

<address name = "ATOPIC">
   <multicast/>
</address>

其次，您的 MDB 應該使用相同的訂閱名稱而不是clientId訂閱ATOPIC ，例如：

@MessageDriven(name = "TOPICMDB1", activationConfig = { 
    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
    @ActivationConfigProperty(propertyName = "destination", propertyValue = "ATOPIC"),
    @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
    @ActivationConfigProperty(propertyName = "subscriptionName", propertyValue = "mytopicSubscription"),
    @ActivationConfigProperty(propertyName = "subscriptionDurability", propertyValue = "Durable"),
    @ActivationConfigProperty(propertyName = "shareSubscriptions", propertyValue="true")
})

@MessageDriven(name = "TOPICMDB2", activationConfig = {
    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
    @ActivationConfigProperty(propertyName = "destination", propertyValue = "ATOPIC"),
    @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"), 
    @ActivationConfigProperty(propertyName = "subscriptionName", propertyValue = "mytopicSubscription"),
    @ActivationConfigProperty(propertyName = "subscriptionDurability", propertyValue = "Durable"),
    @ActivationConfigProperty(propertyName = "shareSubscriptions", propertyValue="true")
})      

第三，您不應該在ATOPIC上手動創建共享的持久消費者。
