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，但是当我运行在 ActiveMQ 面板中进行项目时，只有其中一个主题有消费者！

那么我应该为每个 JmsListener 添加单独的 jmsListenerContainerFactory 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 配置文件：

@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.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

我认为问题在于您为两个侦听器使用的 JmsListenerContainerFactory 设置了 1 的并发性。

如果需要，您可以创建多个 JmsListenerContainerFactory 并通过指定 JmsListener#containerFactory 属性.

将它们设置为 JmsListener

Answer 2

我发现通过将 setClientID() 从 ActiveMQConnectionFactory 提供程序方法移动到 DefaultJmsListenerContainerFactory 提供程序方法，

我只能为每个 jmsListener 使用一个全局 ActiveMQConnectionFactory 提供程序方法和多个 DefaultJmsListenerContainerFactory 提供程序方法：

所以最终的工作代码是：

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;
}

}

jms 听众将是

@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 {
...
}

您可以建立多个 JMSFactory 连接。默认的 JMS 侦听器只接受单例连接工厂对象。所以你需要设置两个 jmslistenercontainerfactory 本身的 bean。

连接到单个主题的代码如下：

@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 listener message receiver class 的代码是这样的，你可以提供 destination 作为主题名称，对于 factory，你可以提供我们上面设置的连接工厂的 bean:

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