java - 使用 JNDI 与 Spring Boot 连接 JMS 队列

Question

我很难弄清楚如何实现 Spring Boot JMS 监听器，监听 JBoss 应用服务器中的 ActiveMQ 队列。因此我选择发布一个问题并用我的最终解决方案来回答它，希望它能为你们中的一些人节省几个小时。

Answer 1

ActiveMQ 受 Spring Boot 自动配置支持，但由于它位于 JBoss 服务器内部，因此 Spring Boot 无法连接 ActiveMQ。事实上，您需要通过查找 JNDI 提供程序来自己定义 connectionFactory 和 jmsListenerContainerFactory bean。

@Configuration
@EnableJms
public class ActiveMqConnectionFactoryConfig {

  @Value("${broker.url}")
  String brokerUrl;

  @Value("${borker.username}")
  String userName;

  @Value("${borker.password}")
  String password;

  @Value("${queue}")
  String queueName;

  private static final String INITIAL_CONTEXT_FACTORY = "org.jboss.naming.remote.client.InitialContextFactory";
  private static final String CONNECTION_FACTORY = "jms/RemoteConnectionFactory";


  @Bean
  public ConnectionFactory connectionFactory() {
    try {
      System.out.println("Retrieving JMS queue with JNDI name: " + CONNECTION_FACTORY);
      JndiObjectFactoryBean jndiObjectFactoryBean = new JndiObjectFactoryBean();
      jndiObjectFactoryBean.setJndiName(CONNECTION_FACTORY);

      jndiObjectFactoryBean.setJndiEnvironment(getEnvProperties());
      jndiObjectFactoryBean.afterPropertiesSet();

      return (QueueConnectionFactory) jndiObjectFactoryBean.getObject();

    } catch (NamingException e) {
      System.out.println("Error while retrieving JMS queue with JNDI name: [" + CONNECTION_FACTORY + "]");
    } catch (Exception ex) {
      System.out.println("Error");
    }
    return null;
  }

  Properties getEnvProperties() {
    Properties env = new Properties();
    env.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);
    env.put(Context.PROVIDER_URL, brokerUrl);
    env.put(Context.SECURITY_PRINCIPAL, userName);
    env.put(Context.SECURITY_CREDENTIALS, password);
    return env;
  }

  @Bean
  public DefaultJmsListenerContainerFactory jmsListenerContainerFactory(ConnectionFactory connectionFactory) {

    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    factory.setConnectionFactory(connectionFactory);
    JndiDestinationResolver jndiDestinationResolver = new JndiDestinationResolver();

    jndiDestinationResolver.setJndiEnvironment(getEnvProperties());
    factory.setDestinationResolver(jndiDestinationResolver);
    return factory;
  }

然后，如果你想使用队列，你只需定义你的 JMS 消费者类，方法用 @JmsListener(destination = "${queue}") 注释

 @JmsListener(destination = "${queue}")
  public void receive(Message message) {
    System.out.println("Received Message: " + message);
  }

希望这有助于节省几个小时的研究；)
