如何使用JNDI访问嵌入式HornetQ

Question

我有一个通用的生产者程序，它查找JNDI资源以连接到JMS代理并发送消息。

我正在为集成测试设置嵌入式HornetQ。这是我用来启动服务器的服务器代码（运行良好）。 服务器

        Configuration configuration = new ConfigurationImpl();
        configuration.setPersistenceEnabled(false);
        configuration.setSecurityEnabled(false);
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("host", "localhost");
        map.put("port", 5445);
        configuration.getAcceptorConfigurations()
                .add(new TransportConfiguration(NettyAcceptorFactory.class.getName(), map));

        TransportConfiguration connectorConfig = new TransportConfiguration(NettyConnectorFactory.class.getName());

        configuration.getConnectorConfigurations().put("connector", connectorConfig);


        // Step 2. Create the JMS configuration
        JMSConfiguration jmsConfig = new JMSConfigurationImpl();

        // Step 3. Configure the JMS ConnectionFactory
        ArrayList<String> connectorNames = new ArrayList<String>();
        connectorNames.add("connector");
        ConnectionFactoryConfiguration cfConfig = new ConnectionFactoryConfigurationImpl("ConnectionFactory", false,  connectorNames, "/ConnectionFactory");
        jmsConfig.getConnectionFactoryConfigurations().add(cfConfig);

        // Step 4. Configure the JMS Queue
        JMSQueueConfiguration queueConfig = new JMSQueueConfigurationImpl("exampleQueue", null, false, "/queue/exampleQueue");
        jmsConfig.getQueueConfigurations().add(queueConfig);

        // Step 5. Start the JMS Server using the HornetQ core server and the JMS configuration
        EmbeddedJMS jmsServer = new EmbeddedJMS();
        jmsServer.setConfiguration(configuration);
        jmsServer.setJmsConfiguration(jmsConfig);

        jmsServer.start();
        System.out.println("Started Embedded JMS Server");

生产者

Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

Context context = new InitialContext(env);

ConnectionFactory connectionFactory = (ConnectionFactory) context.lookup("ConnectionFactory");
Destination destination = (Destination) context.lookup("/queue/exampleQueue");

Connection connection = connectionFactory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Producer producer = session.createProducer(destination);
connection.start();

TextMessage message = session.createTextMessage("Hello sent at " + new Date());
System.out.println("Sending message: " + message.getText());
producer.send(message);

我该如何为服务器注册JNDI资源，以便生产者可以使用这些属性访问嵌入式服务器。

Answer 1

乍一看，似乎您在ConnectionFactoryConfigurationImpl上创建了一个绑定，使用"/cf"作为绑定。但在您的生产者代码中，您查找"ConnectionFactory"。

HornetQ提供了一个简单的嵌入式示例，请考虑查看https://github.com/hornetq/hornetq/tree/2.3.x/examples/jms/embedded-simple。

谢谢Francisco，它已经部分解决了问题。现在我只需要找到一种方法来配置嵌入式服务器以打开一个特定的端口与生产者/消费者进行通信，例如端口1099。不知道嵌入式hornetq使用什么默认端口。 - GBP

我正在使用HornetQBootstrapServer启动HornetQ。

HornetQBootstrapServer hornetQ = new HornetQBootstrapServer(hornetq-beans.xml)
hornetQ.run();
.
.
.
//to stop
hornetQ.shutDown();

I keep hornetq-beans.xml, hornetq-configuration.xml and hornetq-jms.xml in the classpath.

hornetq-beans.xml的示例内容：

<bean name="Naming" class="org.jnp.server.NamingBeanImpl"/>
<!-- JNDI server. Disable this if you don't want JNDI -->
<bean name="JNDIServer" class="org.jnp.server.Main">
  <property name="namingInfo">
     <inject bean="Naming"/>
  </property>
  <property name="port">1099</property>
  <property name="bindAddress">localhost</property>
  <property name="rmiPort">1098</property>
  <property name="rmiBindAddress">localhost</property>
</bean>

<!-- MBean server -->
<bean name="MBeanServer" class="javax.management.MBeanServer">
  <constructor factoryClass="java.lang.management.ManagementFactory"
               factoryMethod="getPlatformMBeanServer"/>
</bean> 

.
.
.

这是我启用嵌入式HornetQ的JNDI的方法。
