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，其中一个主题只有消费者！

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;
    }
}

我认为问题在于您已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属性为JmsListener设置它们。

Answer 2

我发现从ActiveMQConnectionFactory提供程序方法移动setClientID()到DefaultJmsListenerContainerFactory提供程序方法，

我只能为每个jmsListener提供一个全局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;
}

}

和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 {
...
}

如何为多个主题配置多个JmsListener
