无法将消息发送到JBoss EAP 7.2中嵌入的远程ActiveMQ Artemis

问题描述 投票：0回答：1

我正在尝试将JMS消息发送到JBoss EAP 7.2中嵌入的远程ActiveMQ Artemis队列。我在standalone-full.xml中定义了以下内容：

  1. 远程连接器
  2. 池连接工厂
  3. 远程绑定
<subsystem xmlns="urn:jboss:domain:messaging-activemq:4.0">

下面是我的客户程序：

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();
            }
        }
    }
}

我收到以下异常：

有人可以建议我我在这里做什么错吗？

为了将JMS消息发送到JBoss EAP中嵌入的远程ActiveMQ Artemis队列，可以使用默认的standalone-full.xml。您不需要设置远程连接器，池化连接工厂，或远程绑定。您只需要使用JBoss EAP JNDI上下文从客户端中查找jms/RemoteConnectionFactory。需要明确的是，当ActiveMQ Artemis嵌入JBoss EAP远程客户端时，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。您应该改用它：

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：您也可以在此处使用org.jboss.naming.remote.client.InitialContextFactory，因为JBoss EAP 7.2也附带了该类。但是，实际上包含该类是为了与旧版客户端向后兼容。

然后您的客户端尝试查找您在pooled-connection-factory中配置的standalone-full.xml：

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

这也是不正确的。在与JBoss EAP相同的JVM中运行的客户端（例如，需要发送消息的MDB）可以only使用pooled-connection-factory。您不能简单地从远程客户端查找它并期望获得池。那不是它的工作原理。您应该改为这样做：

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

这将使用connection-factory中名为standalone-full.xml的默认RemoteConnectionFactory。

然后，您正在查找甚至在消息传递子系统（即java:global/remoteContext/ImportantMessages）中未定义的队列。您出于某种原因显然已经在external-context中对其进行了配置。对于EAP，这是错误的。您应该在standalone-full.xml中定义它：

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

然后在您的客户端中使用它：

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

最终，这是您在standalone-full.xml中的消息传递子系统应该看起来像的样子：

<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external-context。

最后，这是您的客户最终应该看起来的样子：

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有许多“快速入门”应用程序可用来演示如何使用其功能。这是JMS "Hello World" quickstart，可能会为您提供参考。

如果使用Maven构建客户端应用程序，则应使用此依赖项：

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

[此外，请记住，默认情况下，嵌入在JBoss EAP 7.2中的ActiveMQ Artemis是安全的，因此您将需要禁用消息传递子系统中的安全性（例如，使用<security enabled="false"/>）或将用户添加到ApplicationRealm中（例如，通过bin/add-user.sh脚本），然后在您create your connection时传递适当的凭据。
