有人可以提供在 Wildfly 10 集群（域）下工作的消息传递应用程序的示例吗？我们正在为此苦苦挣扎，鉴于它是一项新技术，资源严重缺乏。
目前我们有以下内容：
由两台主机（节点）和每台上的三个组组成的域，即域中的六个独立服务器。
服务器配置的相关部分（在 domain.xml 中）：
<subsystem xmlns="urn:jboss:domain:messaging-activemq:1.0">
<server name="default">
<security enabled="false"/>
<cluster password="${jboss.messaging.cluster.password}"/>
<security-setting name="#">
<role name="guest" delete-non-durable-queue="true" create-non-durable-queue="true" consume="true" send="true"/>
</security-setting>
<address-setting name="#" redistribution-delay="1000" message-counter-history-day-limit="10" page-size-bytes="2097152" max-siz
<http-connector name="http-connector" endpoint="http-acceptor" socket-binding="http"/>
<http-connector name="http-connector-throughput" endpoint="http-acceptor-throughput" socket-binding="http">
<param name="batch-delay" value="50"/>
</http-connector>
<in-vm-connector name="in-vm" server-id="0"/>
<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"/>
<broadcast-group name="bg-group1" connectors="http-connector" jgroups-channel="activemq-cluster" jgroups-stack="tcphq"/>
<discovery-group name="dg-group1" jgroups-channel="activemq-cluster" jgroups-stack="tcphq"/>
<cluster-connection name="my-cluster" discovery-group="dg-group1" connector-name="http-connector" address="jms"/>
<jms-queue name="ExpiryQueue" entries="java:/jms/queue/ExpiryQueue"/>
<jms-queue name="DLQ" entries="java:/jms/queue/DLQ"/>
<jms-queue name="TestQ" entries="java:jboss/exported/jms/queue/testq"/>
<connection-factory name="InVmConnectionFactory" entries="java:/ConnectionFactory" connectors="in-vm"/>
<connection-factory name="RemoteConnectionFactory" reconnect-attempts="-1" block-on-acknowledge="true" ha="true" entries="java
<pooled-connection-factory name="activemq-ra" transaction="xa" entries="java:/JmsXA java:jboss/DefaultJMSConnectionFactory" co
</server>
</subsystem>
配置或多或少是默认的，除了添加了TestQ队列。
tcphq栈在 JGroups 配置中定义如下：
<stack name="tcphq">
<transport type="TCP" socket-binding="jgroups-tcp-hq"/>
<protocol type="TCPPING">
<property name="initial_hosts">
dev1[7660],dev1[7810],dev1[7960],dev2[7660],dev2[7810],dev2[7960]
</property>
<property name="port_range">
0
</property>
</protocol>
<protocol type="MERGE3"/>
<protocol type="FD_SOCK" socket-binding="jgroups-tcp-hq-fd"/>
<protocol type="FD"/>
<protocol type="VERIFY_SUSPECT"/>
<protocol type="pbcast.NAKACK2"/>
<protocol type="UNICAST3"/>
<protocol type="pbcast.STABLE"/>
<protocol type="pbcast.GMS"/>
<protocol type="MFC"/>
<protocol type="FRAG2"/>
</stack>
我编写了一个由简单的“服务器”组成的测试应用程序，即 MDB 和客户端，如下所示：
服务器（MDB）：
@MessageDriven(mappedName = "test", activationConfig = {
@ActivationConfigProperty(propertyName = "subscriptionDurability", propertyValue = "Durable"),
@ActivationConfigProperty(propertyName = "destination", propertyValue = "java:jboss/exported/jms/queue/testq"),
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue")
})
public class MessageServer implements MessageListener {
@Override
public void onMessage(Message message) {
try {
ObjectMessage msg = null;
if (message instanceof ObjectMessage) {
msg = (ObjectMessage) message;
}
System.out.print("The number in the message: "+ msg.getIntProperty("count"));
} catch (JMSException ex) {
Logger.getLogger(MessageServer.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
客户：
@Singleton
@Startup
public class ClientBean implements ClientBeanLocal {
@Resource(mappedName = "java:jboss/exported/jms/RemoteConnectionFactory")
private ConnectionFactory factory;
@Resource(mappedName = "java:jboss/exported/jms/queue/testq")
private Queue queue;
@PostConstruct
public void sendMessage() {
Connection connection = null;
try {
connection = factory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
MessageProducer producer = session.createProducer(queue);
Message message = session.createObjectMessage();
message.setIntProperty("count", 1);
producer.send(message);
System.out.println("Message sent.");
} catch (JMSException ex) {
Logger.getLogger(ClientBean.class.getName()).log(Level.SEVERE, null, ex);
} catch (NamingException ex) {
Logger.getLogger(ClientBean.class.getName()).log(Level.SEVERE, null, ex);
} finally {
try {
if (connection != null) connection.close();
} catch (JMSException ex) {
Logger.getLogger(ClientBean.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
}
如果客户端和服务器都驻留在同一个组中，它实际上工作得很好。在这种情况下，它甚至似乎在主机（节点）之间进行通信。但是，如果服务器和客户端在不同的组中，则不会调用 MDB。此外，似乎只有当它位于偏移量为 0 的组中时才调用 MDB。当我将服务器 MDB 移动到不同的组时，即使客户端在同一组中，它也没有响应。
我对 Wildfly 10 中的 JMS 有点困惑。HornetQ 的旧版本有很多示例和材料，但对于 Artemis 来说却很少。有人可以帮忙吗？非常感谢。
