Spring AMQP questions should be directed to Stack Overflow, tag spring-amqp. We do not maintain
that project.

Yes; please use Stack Overflow for Spring AMQP.

That said...

Caused by: java.lang.IllegalArgumentException: 'connectionFactory' or 'rabbitTemplate' is required

at org.springframework.amqp.rabbit.core.support.RabbitGatewaySupport.afterPropertiesSet(RabbitGatewaySupport.java:99) ~[spring-rabbit-1.4.3.RELEASE.jar:na]

You don't show a RabbitGatewaySupport in your configuration (presumably messageQueueSender is a subclass) but the error is pretty clear - it needs one of the required dependencies.

But, please continue this discussion on Stack Overflow.

Will post to Stackoverflow in future.  

Here is the class that extends RabbitGatewaySupport.

@Service("messageQueueSender")

public class MessageQueueSenderImpl extends RabbitGatewaySupport implements MessageQueueSender {

    @Override

    public void sendMessage(final Message message) {

        getRabbitTemplate().convertAndSend(message);

[Gary Russell]

Right, but you are not showing a configuration for it; you need an @Bean definition for it and need to provide it with a reference to your rabbitTemplate bean in its @Bean definition...

messageQueueSender.setRabbitTemplate(rabbitTemplate());

You can't use autowiring/component scan for this component unless you @Autwire your own RabbitTemplate (to be honest, there is not much value in subclassing the gateway for your scenario, using java config).

To post to this group, send email to rabbitm...@googlegroups.com.

[Gary Russell]

@Service("messageQueueSender")

public class MessageQueueSenderImpl implements MessageQueueSender {

    @Autowired

    private RabbitTemplate;

    @Override

    public void sendMessage(final Message message) {

        thia.rabbitTemplate.convertAndSend(message);

    }

}

If you have more questions, please move it to Stack Overflow rather than polluting this group.
