用于应用程序上下文的Bean引用的Spring集成表达式

Question

I have a doubt that if is possible to resolve a bean reference for a JMS destination to config a JMS Adapter.

I have several destination configured as follows on Spring:

<jee:jndi-lookup id="BeanID" jndi-name="jms/QUEUE" lazy-init="false"/>

Then i put a value on the Message Headers with the value like :

@ServiceActivator
public Message<?> sendToJms(Message<?> messageInput){ 
    String queueName = solveQueueName(refToSolveBeanID); 
    return MessageBuilder.withPayload(messageInput.getPayLoad()).setHeader("beanIdHeaderRef, queueName ).builder();
}

Now my problem is how to construct the expression to solve the bean reference on Spring Context for the following configuration works.

<int:chain input-channel="jmsChannel">
        <jms:outbound-channel-adapter  
            connection-factory="solicitacaoConnFactory"   destination-expression="headers.beanIdHeaderRef">
        </jms:outbound-channel-adapter>
    </int:chain>

as you notice the JMS Destination is configured using the jndi-lookup i tried some variations but all failed. I thought that is have to pass to the BeanFactory the header value, but have no idea how to create the expression, does anyone know how the expression should look like?

Regards.

Looking to your code I don't see reason to have some access to the BeanFactory from the SpEL. You can just resolve your refToSolveBeanID to the target Destination and place that object to the headers directly.

Your SpEL will be the same though.
