我试图向JBoss EAP 7.2中嵌入的远程ActiveMQ Artemis队列发送JMS消息。我在《独立完整》中定义了以下内容。xml:

  1. 远程连接器
  2. 汇集连接工厂
  3. 远程绑定

以下是我的客户程序:

public void sendObjectMessage() {
    Properties initialProperties = new Properties();
    initialProperties.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory");
    initialProperties.put(InitialContext.PROVIDER_URL, "tcp://127.0.0.1:61616");
    try {
        context = new InitialContext(initialProperties);
        factory = (QueueConnectionFactory) context.lookup("java:/jms/remoteIM");
        destination = (Queue) context.lookup("java:global/remoteContext/ImportantMessages");
        connection = factory.createConnection();
        session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        producer = session.createProducer(destination);
        EventMessage eventMessage = new EventMessage("1", "Message from FirstClient");
        ObjectMessage objectMessage = session.createObjectMessage();
        objectMessage.setObject(eventMessage);
        connection.start();
        producer.send(objectMessage);
        System.out.println(this.getClass().getName() + "has sent a message : " + eventMessage);
    } catch (NamingException e) {
        e.printStackTrace();
    } catch (JMSException e) {
        e.printStackTrace();
    } finally {
        if (context != null) {
            try {
                context.close();
            } catch (NamingException ex) {
                ex.printStackTrace();
            }
        }
        if (connection != null) {
            try {
                connection.close();
            } catch (JMSException ex) {
                ex.printStackTrace();
            }
        }
    }
}

我得到以下例外:

有人能告诉我我做错了什么吗?

为了向JBoss EAP中嵌入的远程ActiveMQ Artemis队列发送JMS消息,可以使用默认的standalone full。xml。您不需要设置远程连接器、池连接工厂或远程绑定。您只需使用JBoss EAP JNDI上下文从客户端查找jms/RemoteConnectionFactory。需要明确的是,当ActiveMQ Artemis嵌入JBoss EAP时,远程客户端使用JBoss EAP JNDI上下文,而不是ActiveMQ Artemis JNDI上下文,因为EAP本身负责所有JNDI操作。

您的客户端正在使用ActiveMQ Artemis JNDI上下文:

initialProperties.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory");
initialProperties.put(InitialContext.PROVIDER_URL, "tcp://127.0.0.1:61616");

这是不正确的。你应该用这个代替:

initialProperties.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");
initialProperties.put(InitialContext.PROVIDER_URL, "http-remoting://127.0.0.1:8080");

注意:你也可以使用org。jboss。命名。遥控器。客户InitialContextFactory,因为该类也随JBoss EAP 7.2一起提供。然而,这个类实际上是为了向后兼容遗留客户端。

然后,您的客户端正在尝试查找您在standalone-full.xml中配置的pooled-Connection-Factory

factory = (QueueConnectionFactory) context.lookup("java:/jms/remoteIM");

这也是不正确的。池连接工厂只能由与JBoss EAP在同一JVM中运行的客户端使用(例如,需要发送消息的MDB)。你不能简单地从远程客户端查找它,然后期望得到池。事情不是这样的。你应该这样做:

factory = (QueueConnectionFactory) context.lookup("jms/RemoteConnectionFactory");

这将使用standalone-full.xml中的默认连接工厂。

然后,您正在查找一个消息子系统中甚至没有定义的队列(即java:global/remoteContext/ImportantMessages)。出于某种原因,您显然在外部上下文中配置了它。这对EAP来说是错误的。您应该在独立完整版中定义这一点。xml

<jms-queue name="ImportantMessages" entries="java:jboss/exported/ImportantMessages"/>

然后在你的客户中使用:

destination = (Queue) context.lookup("ImportantMessages");

最终,这就是您的消息子系统在独立版中的完整功能。xml应该如下所示:

xml prettyprint-override"><subsystem xmlns="urn:jboss:domain:messaging-activemq:4.0">
    <server name="default">
        <journal pool-files="10"/>
        <security-setting name="#">
            <role name="guest" send="true" consume="true" create-non-durable-queue="true" delete-non-durable-queue="true"/>
        </security-setting>
        <address-setting name="#" dead-letter-address="jms.queue.DLQ" expiry-address="jms.queue.ExpiryQueue" max-size-bytes="10485760" page-size-bytes="2097152" message-counter-history-day-limit="10"/>
        <http-connector name="http-connector" socket-binding="http" endpoint="http-acceptor"/>
        <http-connector name="http-connector-throughput" socket-binding="http" endpoint="http-acceptor-throughput">
            <param name="batch-delay" value="50"/>
        </http-connector>
        <in-vm-connector name="in-vm" server-id="0">
            <param name="buffer-pooling" value="false"/>
        </in-vm-connector>
        <http-acceptor name="http-acceptor" http-listener="default"/>
        <http-acceptor name="http-acceptor-throughput" http-listener="default">
            <param name="batch-delay" value="50"/>
            <param name="direct-deliver" value="false"/>
        </http-acceptor>
        <in-vm-acceptor name="in-vm" server-id="0">
            <param name="buffer-pooling" value="false"/>
        </in-vm-acceptor>
        <jms-queue name="ImportantMessages" entries="java:jboss/exported/ImportantMessages"/>
        <jms-queue name="ExpiryQueue" entries="java:/jms/queue/ExpiryQueue"/>
        <jms-queue name="DLQ" entries="java:/jms/queue/DLQ"/>
        <connection-factory name="InVmConnectionFactory" entries="java:/ConnectionFactory" connectors="in-vm"/>
        <connection-factory name="RemoteConnectionFactory" entries="java:jboss/exported/jms/RemoteConnectionFactory" connectors="http-connector"/>
        <pooled-connection-factory name="activemq-ra" entries="java:/JmsXA java:jboss/DefaultJMSConnectionFactory" connectors="in-vm" transaction="xa"/>   
    </server>
</subsystem>

您不需要配置的外部上下文

最后,你的客户最终应该是这样的:

public void sendObjectMessage() {
    Properties initialProperties = new Properties();
    initialProperties.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");
    initialProperties.put(InitialContext.PROVIDER_URL, "http-remoting://127.0.0.1:8080");
    try {
        context = new InitialContext(initialProperties);
        factory = (QueueConnectionFactory) context.lookup("jms/RemoteConnectionFactory");
        destination = (Queue) context.lookup("ImportantMessages");
        connection = factory.createConnection();
        session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        producer = session.createProducer(destination);
        EventMessage eventMessage = new EventMessage("1", "Message from FirstClient");
        ObjectMessage objectMessage = session.createObjectMessage();
        objectMessage.setObject(eventMessage);
        connection.start();
        producer.send(objectMessage);
        System.out.println(this.getClass().getName() + "has sent a message : " + eventMessage);
    } catch (NamingException e) {
        e.printStackTrace();
    } catch (JMSException e) {
        e.printStackTrace();
    } finally {
        if (context != null) {
            try {
                context.close();
            } catch (NamingException ex) {
                ex.printStackTrace();
            }
        }
        if (connection != null) {
            try {
                connection.close();
            } catch (JMSException ex) {
                ex.printStackTrace();
            }
        }
    }
}

JBoss EAP提供了一系列“快速入门”应用程序来演示如何使用其功能。以下是JMS“Hello World”快速入门,您可能会发现它对参考很有用。

如果您正在使用Maven构建客户端应用程序,那么这就是您应该使用的依赖项:

<dependency>
    <groupId>org.jboss.eap</groupId>
    <artifactId>wildfly-jms-client-bom</artifactId>
    <type>pom</type>
</dependency>

另外,请记住,JBoss EAP 7.2中嵌入的ActiveMQ Artemis在默认情况下是安全的,因此您需要禁用消息子系统中的安全性(例如使用
