如何为多个主题配置多个JmsListener

Question

在我的项目中，我添加了两个不同的JmsListener，但是当我在ActiveMQ面板中运行项目时，只有其中一个主题有使用者！

那么，我应该为每个jmsListenerContainerFactory添加单独的JmsListener配置吗？

@JmsListener(destination = "foo1")
public void foo1(final Message jsonMessage) throws JMSException {
    ...
}

@JmsListener(destination = "foo2")
public void foo12(final Message jsonMessage) throws JMSException {
    ...
}

编辑：--这是来自JMS文件的：

@Configuration
@EnableJms
public class FooJmsConfig {

    @Bean
    public ActiveMQConnectionFactory connectionFactory() {
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
        connectionFactory.setBrokerURL(BROKER_URL);
        connectionFactory.setPassword(BROKER_USERNAME);
        connectionFactory.setUserName(BROKER_PASSWORD);
        connectionFactory.setUseCompression(true);
        connectionFactory.setClientID("FPP_API");
        connectionFactory.setConnectionIDPrefix("DRR");
        connectionFactory.setUseAsyncSend(true);
        return connectionFactory;
    }

    @Bean
    public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory());
        factory.setConcurrency("1-1");
        factory.setPubSubDomain(true);
        factory.setSubscriptionDurable(true);
        return factory;
    }
}

Answer 1

我发现通过移动setClientID() 从ActiveMQConnectionFactory提供程序方法到DefaultJmsListenerContainerFactory提供者方法，

对于每个ActiveMQConnectionFactory，我只能有一个全局DefaultJmsListenerContainerFactory提供程序方法和多个jmsListener提供程序方法：

因此，最终的工作代码是：

JMSConfig文件：

@Configuration
@EnableJms
public class FooJmsConfig {

@Bean
public ActiveMQConnectionFactory connectionFactory() {
    ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
    connectionFactory.setBrokerURL(BROKER_URL);
    connectionFactory.setPassword(BROKER_USERNAME);
    connectionFactory.setUserName(BROKER_PASSWORD);
    connectionFactory.setUseCompression(true);

    connectionFactory.setConnectionIDPrefix("DRR");
    connectionFactory.setUseAsyncSend(true);
    return connectionFactory;
}

@Bean(name= "foo1")
public DefaultJmsListenerContainerFactory foo1() {
    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    factory.setConnectionFactory(connectionFactory());
    factory.setConcurrency("1-1");
    factory.setPubSubDomain(true);
    factory.setSubscriptionDurable(true);

    connectionFactory.setClientID("FOO_1");
    return factory;
}

 @Bean(name= "foo2")
public DefaultJmsListenerContainerFactory foo2() {
    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    factory.setConnectionFactory(connectionFactory());
    factory.setConcurrency("1-1");
    factory.setPubSubDomain(true);
    factory.setSubscriptionDurable(true);

    connectionFactory.setClientID("FOO_1");
    return factory;
}

}

而jms的侦听器将是

@JmsListener(destination = "foo1", containerFactory="foo1")
public void foo1(final Message jsonMessage) throws JMSException {
...
}

@JmsListener(destination = "foo2", containerFactory="foo2")
public void foo12(final Message jsonMessage) throws JMSException {
...
}

我认为问题在于您已经在1上为两个侦听器使用的JmsListenerContainerFactory设置了并发性。

如果需要，您可以创建多个JmsListenerContainerFactory，并通过指定JmsListener#containerFactory属性为JmsListener设置它们。

Answer 3

可以建立多个JMSFactory连接。默认JMS侦听器只接受单例连接工厂对象。因此，您需要设置jmslistenercontainerfactory本身的两个bean。

连接到单个主题的代码如下所示：

@Configuration
@EnableJms
@EnableTransactionManagement
public class JMSConnectionConfig{

private static final String AMQP_URI_FORMAT = "amqps://%s?amqp.idleTimeout=%d";

private int idleTimeout;

private String hostURL;

@Bean(name = "cachingConnectionFactory1")
@Primary
public ConnectionFactory myConnectionFactory1() {
    // set up connection details to the topic
    String remoteUri = String.format(AMQP_URI_FORMAT, hostURL, idleTimeout);
    JmsConnectionFactory jmsConnectionFactory = new JmsConnectionFactory();
    jmsConnectionFactory.setRemoteURI(remoteUri);
    jmsConnectionFactory.setClientID(clientId);
    jmsConnectionFactory.setUsername(topic1SASName);
    jmsConnectionFactory.setPassword(topic1SASKey);
    // create caching factory object and return as connectionfactory parent object
    CachingConnectionFactory cachingConnectionFactory = new CachingConnectionFactory();
    cachingConnectionFactory.setTargetConnectionFactory(jmsConnectionFactory);
    cachingConnectionFactory.setReconnectOnException(true);
    return cachingConnectionFactory;
}

@Bean(name = "factory1")
public JmsListenerContainerFactory<?> factory1(@Qualifier("cachingConnectionFactory1") ConnectionFactory connectionFactory,
                                                DefaultJmsListenerContainerFactoryConfigurer configurer) {
    DefaultJmsListenerContainerFactory topicFactory = new DefaultJmsListenerContainerFactory();
    topicFactory.setConnectionFactory(connectionFactory);
    topicFactory.setSubscriptionDurable(Boolean.TRUE);
    // configure DefaultJmsListenerContainerFactoryConfigurer with caching factory and listener factory
    configurer.configure(topicFactory, connectionFactory);
    return topicFactory;
}

// Goes here for another topic in the same way as above two methods to establish initial connection to the topic
}

JMS侦听器消息接收类的代码如下所示，您可以提供目标作为您的主题名称，对于工厂，您可以提供我们前面设置的conenction工厂的bean：

@JmsListener(destination = "${topic.name}", containerFactory = "factory1",
        subscription = "${topic.subscription.name}")
public void receiveMessage(JmsTextMessage jmsTextMessage) throws JMSException, IOException, InterruptedException {
    // listener code goes here
}
