Spring-Boot：如何访问多个JMS代理网址

Question

在Spring-Boot中

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

如果我想发送到一个以上的经纪人 - 或听不同的经纪人 - 如何做？

Answer 1

您无法使用默认的Spring-Boot自动配置访问两个不同的经纪人。

为了解决此问题，您必须像以下示例一样创建自己的配置bean：

@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;
    }
}

在我的 application.yml中，我只参考注射属性（没有设置默认的spring.activemq）：

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

和我的听众bean（假设我只想从两个队列中消耗）

@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);
        }
    }
}

您还可以使用配置中定义的jmsTemplates将消息发布给所需的代理。

Answer 2

spring.activemq.broker-url= # URL of the ActiveMQ broker. Auto-generated by default. For instance `tcp://localhost:61616`
spring.activemq.in-memory=true # Specify if the default broker URL should be in memory. Ignored if an explicit broker has been specified.
spring.activemq.password= # Login password of the broker.
spring.activemq.user= # Login user of the broker.

制作spring.activemq.in-memory=false。如果是真的，那么它将从内存中读取，您将获得另一个。希望它会有所帮助。
