使用ActiveMQ Artemis发送AMQ消息

Question

我想向WildFly服务器上的ActiveMQ Artemis实例发送消息。我使用本教程来尝试配置standalone-full.xml。我正在使用jboss/wwildfly docker映像，并暴露以下netty端口：5445。

独立配置：

<subsystem xmlns="urn:jboss:domain:messaging-activemq:10.0">
<server name="default">
<security enabled="true"/>
<security-setting name="#">
<role name="SuperUser" 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" redistribution-delay="1000"/>
<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"/>
<remote-connector name="netty" socket-binding="messaging"/>
<remote-acceptor name="netty" socket-binding="messaging"/>
<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"/>
<jms-queue name="ExpiryQueue" entries="java:/jms/queue/ExpiryQueue"/>
<jms-queue name="DLQ" entries="java:/jms/queue/DLQ"/>
<jms-queue name="JoeIsCool" entries="java:/jms/queue/JoeIsCool"/>
<connection-factory name="InVmConnectionFactory" connectors="in-vm" entries="java:/ConnectionFactory"/>
<connection-factory name="RemoteConnectionFactory" ha="true" block-on-acknowledge="true" reconnect-attempts="-1" connectors="netty" entries="java:jboss/exported/jms/RemoteConnectionFactory"/>
<pooled-connection-factory name="activemq-ra" transaction="xa" connectors="in-vm" entries="java:/JmsXA java:jboss/DefaultJMSConnectionFactory"/>
</server>
</subsystem>

<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
...
<socket-binding name="messaging" port="5445"/>
...
</socket-binding-group>

我尝试创建一个简单的测试用例，它将向ActiveMQ Artemis实例发送一条消息：

public void sendAmqMessage() throws Exception {
final ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("admin", "secretPassoword", "tcp://localhost:5445");
final Connection connection = connectionFactory.createConnection();
connection.start();
final Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
final Destination destination = session.createQueue("JoeIsCool");
final MessageProducer producer = session.createProducer(destination);
final TextMessage message =
session.createTextMessage("Hello !!! Welcome to the world of ActiveMQ.");
producer.send(message);
connection.close();
}

在执行时，我在我的客户端上得到了这个错误：

javax.jms.JMSException: Cannot send, channel has already failed: tcp://127.0.0.1:5445

我在我的服务器上得到这个错误：

(Thread-1 (activemq-netty-threads)) AMQ214013: Failed to decode packet: java.lang.IllegalArgumentException: AMQ219032: Invalid type: 1

我试着按照这篇帖子回答我自己的问题，但找不到有用的解决方案。

配置ActiveMQ实例时缺少什么？如何使用Java代码对其进行测试？

Answer 1

在sendAmqMessage方法中，您正在创建一个javax.jms.ConnectionFactory实例，如下所示：

final ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("admin", "secretPassoword", "tcp://localhost:5445");

此ActiveMQConnectionFactory来自ActiveMQ 5.x客户端，并且使用OpenWire协议，而standalone-full.xml中的remote-acceptor不理解该协议，因此会出现无法解码传入备份的错误。

正如您下面的文档所建议的那样，与其直接实例化ConnectionFactory，不如简单地在JNDI中查找它，如下所示：

final Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
env.put(Context.PROVIDER_URL, "http-remoting://localhost:8080");
InitialContext remotingCtx = new InitialContext(env);
final ConnectionFactory connectionFactory = (ConnectionFactory) remotingCtx.lookup("jms/RemoteConnectionFactory");

此外，请确保使用正确的依赖项，即：

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

以这种方式使用JNDI还可以将其从standalone-full.xml:中删除

<remote-connector name="netty" socket-binding="messaging"/>
<remote-acceptor name="netty" socket-binding="messaging"/>

除此之外：

<socket-binding name="messaging" port="5445"/>

您实际上只需要在默认standalone-full.xml中定义的资源。
