Spring-integration: Configurable name of @Header-parameter?

I am using Spring-integration for listening to queues, and am now faced with a quite silly bug. It turns out that the name of a message paramter was misspelled, leading to runtime errors. To fix it, I have to rebuild the java-class, since the name of the message attribute is a hardcoded String. I would like to resolve such errors easier in the future, by making the name of the message attributes configurable through a properties-file, but I can't seem to find a way to do it. Is it at all possible?

public void someListenerMethod(@Header("someAttribute")
                               final Long someAttribute) {

I would here like to make the parameter to @Header configurable..

I'll answer myself as I found one way of doing this (although I'm not sure it's optimal..)

@Value("${my.header.property.name}")
private String myHeaderPropertyName;

public void someListenerMethod(@Headers
                               final Map<String, Object> headerAttributes) {
    final Long myHeaderAttribute = (Long) headerAttributes.get(myHeaderPropertyName));
