spring启动配置多个ActiveMQ实例

Question

我需要将消息从一个 ActiveMQ 实例上的队列移动到另一个 ActiveMQ 实例。有没有办法使用 spring 引导配置连接到两个不同的 ActiveMQ 实例？

我需要创建多个connectionFactories吗？如果是这样，那么 JmsTemplate 如何知道要连接到哪个 ActiveMQ 实例？

  @Bean
    public ConnectionFactory connectionFactory() {
        return new ActiveMQConnectionFactory(JMS_BROKER_URL);
    }

任何帮助和代码示例都会很有用。

提前致谢。通用

Answer 1

您需要在您的应用程序中将多个 JmsTemplate 实例实例化为 Beans，然后使用 @Qualifier 和 @Primary 注释的组合来指示哪个 JmsTemplate实例应该去哪里。

例如

@Bean("queue1")
@Primary
public JmsTemplate getQueue1(@Qualifier("connectionFactory1")ConnectionFactory factory...){
...
}

@Bean("queue2")
@Primary
public JmsTemplate getQueue2(@Qualifier("connectionFactory2")ConnectionFactory factory...){
...
}

...

@Autowired
@Qualifier("queue1")
private JmsTemplate queue1;
...

除了@Chris 的回复您必须使用不同的端口创建不同的 BrokerService 实例，并创建不同的 ConnectionFactory 以连接到每个代理，并使用这些不同的工厂创建不同的 JmsTemplate 以将消息发送到不同的代理。

例如：

import javax.jms.ConnectionFactory;
import javax.jms.QueueConnectionFactory;

import org.apache.activemq.ActiveMQConnectionFactory;
import org.apache.activemq.broker.BrokerService;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.jms.config.DefaultJmsListenerContainerFactory;
import org.springframework.jms.config.JmsListenerContainerFactory;
import org.springframework.jms.core.JmsTemplate;

@Configuration
public class ActiveMQConfigurationForJmsCamelRouteConsumeAndForward {
    public static final String LOCAL_Q = "localQ";
    public static final String REMOTE_Q = "remoteQ";

    @Bean
    public BrokerService broker() throws Exception {
        final BrokerService broker = new BrokerService();
        broker.addConnector("tcp://localhost:5671");
        broker.setBrokerName("broker");
        broker.setUseJmx(false);
        return broker;
    }

    @Bean
    public BrokerService broker2() throws Exception {
        final BrokerService broker = new BrokerService();
        broker.addConnector("tcp://localhost:5672");
        broker.setBrokerName("broker2");
        broker.setUseJmx(false);
        return broker;
    }

    @Bean
    @Primary
    public ConnectionFactory jmsConnectionFactory() {
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:5671");
        return connectionFactory;
    }

    @Bean
    public QueueConnectionFactory jmsConnectionFactory2() {
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:5672");
        return connectionFactory;
    }

    @Bean
    @Primary
    public JmsTemplate jmsTemplate() {
        JmsTemplate jmsTemplate = new JmsTemplate();
        jmsTemplate.setConnectionFactory(jmsConnectionFactory());
        jmsTemplate.setDefaultDestinationName(LOCAL_Q);
        return jmsTemplate;
    }

    @Bean
    public JmsTemplate jmsTemplate2() {
        JmsTemplate jmsTemplate = new JmsTemplate();
        jmsTemplate.setConnectionFactory(jmsConnectionFactory2());
        jmsTemplate.setDefaultDestinationName(REMOTE_Q);
        return jmsTemplate;
    }

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

    @Bean
    public JmsListenerContainerFactory<?> jmsListenerContainerFactory2(
            @Qualifier("jmsConnectionFactory2") ConnectionFactory connectionFactory,
            DefaultJmsListenerContainerFactoryConfigurer configurer) {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        configurer.configure(factory, connectionFactory);
        return factory;
    }
}

要将消息从一个 AMQ 实例移动到另一个实例，您可以使用 JmsBridgeConnectors :

请注意，在下面的示例中，您不能在要从中转发消息的队列中有多个消费者，因为 Camel 或 JmsBridgeConnectors 会使用消息并转发它。如果您希望转发邮件的唯一副本，您有一些解决方案： 1- 将您的队列转换为主题，通过持久订阅或追溯消费者管理离线消费者的消息。 2- 将您的队列转换为复合队列并使用 DestinationsInterceptors 将消息复制到另一个队列。 3- 将 NetworkConnector 用于 Networkof brokers

@Bean
public BrokerService broker() throws Exception {
    final BrokerService broker = new BrokerService();
    broker.addConnector("tcp://localhost:5671");
    SimpleJmsQueueConnector simpleJmsQueueConnector = new SimpleJmsQueueConnector();
    OutboundQueueBridge bridge = new OutboundQueueBridge();
    bridge.setLocalQueueName(LOCAL_Q);
    bridge.setOutboundQueueName(REMOTE_Q);
    OutboundQueueBridge[] outboundQueueBridges = new OutboundQueueBridge[] { bridge };
    simpleJmsQueueConnector.getReconnectionPolicy().setMaxSendRetries(ReconnectionPolicy.INFINITE);
    simpleJmsQueueConnector.setOutboundQueueBridges(outboundQueueBridges);
    simpleJmsQueueConnector.setLocalQueueConnectionFactory((QueueConnectionFactory) jmsConnectionFactory());
    simpleJmsQueueConnector.setOutboundQueueConnectionFactory(jmsConnectionFactory2());
    JmsConnector[] jmsConnectors = new JmsConnector[] { simpleJmsQueueConnector };
    broker.setJmsBridgeConnectors(jmsConnectors);
    broker.setBrokerName("broker");
    broker.setUseJmx(false);
    return broker;
}

或者像下面这样使用 Camel :

@Bean
public CamelContext camelContext() throws Exception {
    CamelContext context = new DefaultCamelContext();
    context.addComponent("inboundQueue", ActiveMQComponent.activeMQComponent("tcp://localhost:5671"));
    context.addComponent("outboundQueue", ActiveMQComponent.activeMQComponent("tcp://localhost:5672"));
    context.addRoutes(new RouteBuilder() {
        public void configure() {
            from("inboundQueue:queue:" + LOCAL_Q).to("outboundQueue:queue:" + REMOTE_Q);
        }
    });
    context.start();
    return context;
}

您的生产者必须像这样才能使用不同的 JmsTemplates :

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.CommandLineRunner;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Component;

@Component
public class Producer implements CommandLineRunner {

    @Autowired
    private JmsTemplate jmsTemplate;

    @Autowired
    @Qualifier("jmsTemplate2")
    private JmsTemplate jmsTemplate2;

    @Override
    public void run(String... args) throws Exception {
        send("Sample message");
    }

    public void send(String msg) {
        this.jmsTemplate.convertAndSend(ActiveMQConfigurationForJmsCamelRouteConsumeAndForward.LOCAL_Q, msg);
        this.jmsTemplate2.convertAndSend(ActiveMQConfigurationForJmsCamelRouteConsumeAndForward.REMOTE_Q, msg);
    }
}

和消费者：

import javax.jms.Session;

import org.apache.activemq.ActiveMQSession;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

@Component
public class Consumer {

    @JmsListener(destination = ActiveMQConfigurationForJmsCamelRouteConsumeAndForward.REMOTE_Q, containerFactory = "jmsListenerContainerFactory2")
    public void receiveQueue(Session session, String text) {
        System.out.println(((ActiveMQSession) session).getConnection().getBrokerInfo());
        System.out.println(text);
    }
}

Answer 3

您可以使用 Spring 队列消费者的默认引导

@JmsListener(destination = “queue.name")
public void consumer(String message) {
    // consume the message
}

对于生产者，您可以创建另一个 JmsTemplate @Bean

@Bean
public JmsTemplate jmsTemplate() {
    return new JmsTemplate(new ActiveMQConnectionFactory("tcp://localhost:5671"));
}

Answer 4

通过这种方式，您可以动态注册任意数量的 brokers/listeners：

import org.apache.activemq.ActiveMQConnectionFactory;
import org.springframework.context.annotation.Configuration;
import org.springframework.jms.annotation.JmsListenerConfigurer;
import org.springframework.jms.config.DefaultJmsListenerContainerFactory;
import org.springframework.jms.config.JmsListenerEndpointRegistrar;
import org.springframework.jms.config.SimpleJmsListenerEndpoint;

import javax.jms.Message;
import javax.jms.MessageListener;

@Configuration
public class CustomJmsConfigurer implements JmsListenerConfigurer {

    @Override
    public void configureJmsListeners(JmsListenerEndpointRegistrar registrar) {
        ActiveMQConnectionFactory amqConnectionFactory = new ActiveMQConnectionFactory();
        amqConnectionFactory.setBrokerURL("brokerUrl");
        amqConnectionFactory.setUserName("user");
        amqConnectionFactory.setPassword("password");
        amqConnectionFactory.setExclusiveConsumer(true);

        DefaultJmsListenerContainerFactory containerFactory = new DefaultJmsListenerContainerFactory();
        containerFactory.setConnectionFactory(amqConnectionFactory);

        SimpleJmsListenerEndpoint endpoint = new SimpleJmsListenerEndpoint();
        endpoint.setId("someIdentifier");
        endpoint.setDestination("queueName");
        endpoint.setMessageListener(new MessageListener() {

            @Override
            public void onMessage(Message message) {
                // Do your stuff
            }
        });
        registrar.registerEndpoint(endpoint, containerFactory);
    }
}
