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;
    }
}

我发现，通过移动setClientID()从ActiveMQConnectionFactory提供商方法DefaultJmsListenerContainerFactory提供方法，

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

}

和JMS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,问题就在于你已经设置并发上1为JmsListenerContainerFactory使用两个听众.

如果需要,您可以通过指定JmsListener#containerFactory属性来创建多个JmsListenerContainerFactory并为它们设置它们.JmsListener
