Spring-Boot：如何访问多个 JMS 代理 URL

在 Spring-Boot 中，默认的 ActiveMQ (JMS) 属性是：

spring.activemq.broker-url=tcp://192.168.1.210:9876
spring.activemq.user=admin
spring.activemq.password=secret

如果我想发送到多个broker-url或监听不同的broker-url怎么办？

您无法使用默认值访问两个不同的经纪商Spring-Boot自动配置。

为了解决这个问题，您必须创建自己的配置 Bean，如下例所示：

@Configuration
class JmsUtilsConfiguration {

    @Value("${activemq.broker-one.url}")
    private String brokerOneUrl;

    // Im my case, broker-two is secured -> hence username and password need to be configured
    @Value("${activemq.broker-two.url}")
    private String brokerTwoUrl;

    @Value("${activemq.broker-two.username}")
    private String brokerTwoUser;

    @Value("${activemq.broker-two.password}")
    private String brokerTwoPwd;

    @Bean
    @Primary
    public ConnectionFactory jmsConnectionFactoryOne() {
        return new ActiveMQConnectionFactory(brokerOneUrl);
    }

    @Bean
    public QueueConnectionFactory jmsConnectionFactoryTwo() {
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory();
        activeMQConnectionFactory.setBrokerURL(brokerTwoUrl);
        activeMQConnectionFactory.setUserName(brokerTwoUser);
        activeMQConnectionFactory.setPassword(brokerTwoPwd);
        return activeMQConnectionFactory;
    }

    // JmsListenerContainerFactory declarations
    @Bean
    public JmsListenerContainerFactory<?> jmsListenerContainerFactoryOne(
            ConnectionFactory connectionFactory, DefaultJmsListenerContainerFactoryConfigurer configurer) {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        configurer.configure(factory, connectionFactory);
        return factory;
    }

    @Bean
    public JmsListenerContainerFactory<?> jmsListenerContainerFactoryTwo(
            @Qualifier("jmsConnectionFactoryTwo") ConnectionFactory connectionFactory,
            DefaultJmsListenerContainerFactoryConfigurer configurer) {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        configurer.configure(factory, connectionFactory);
        return factory;
    }
    
    // JMS Template Declaration
    
    @Bean
    @Primary
    public JmsTemplate jmsTemplateOne() {
        JmsTemplate jmsTemplate = new JmsTemplate();
        jmsTemplate.setConnectionFactory(jmsConnectionFactoryOne());
        return jmsTemplate;
    }

    @Bean
    public JmsTemplate jmsTemplateTwo() {
        JmsTemplate jmsTemplate = new JmsTemplate();
        jmsTemplate.setConnectionFactory(jmsConnectionFactoryTwo());
        return jmsTemplate;
    }

}

In my application.yml我只是指注入的属性（without设置默认值spring.activemq ones):

activemq:
  broker-one:
    url: tcp://localhost:61616
    local-queue: TEST.LOCAL.INBOUND
  broker-two:
    url: failover:(ssl://myremote-amq-1:61617,ssl://myremote-amq-2:61617)?jms.watchTopicAdvisories=false&timeout=5000&maxReconnectDelay=10000
    username: myuser
    password: mypass
    remote-queue: TEST.REMOTE.QUEUE

在我的侦听器 Bean 中（假设我只想从两个队列中消费）

@Component
public class ConsumeQueuesBean {

    private static final Logger LOGGER = LoggerFactory.getLogger(ConsumeQueuesBean.class);

    @JmsListener(destination = "${activemq.broker-one.local-queue}", containerFactory = "jmsListenerContainerFactoryOne")
    public void onMessageReceiveB1(final Message message) throws JMSException {
        if (message instanceof TextMessage) {
            String text = ((TextMessage) message).getText();
            LOGGER.info(text);
        }
    }


    @JmsListener(destination = "${activemq.broker-two.remote-queue}", containerFactory = "jmsListenerContainerFactoryTwo")
    public void onMessageReceivedB2(final Message message) throws JMSException {
        if (message instanceof TextMessage) {
            String text = ((TextMessage) message).getText();
            LOGGER.info(text);
        }
    }
}

您还可以使用jmsTemplates在配置中定义用于将消息发布到您想要的代理。
