Gateway methods should not expect the mapping annotation to be the first parameter annotation [INT-895]

[spring-operator]

Mark Fisher opened INT-895 and commented

This code is currently in ArgumentArrayMessageMapper.mapArgumentsToMessage(..):

Annotation annotation = methodParam.getParameterAnnotations().length == 0 
        ? null : (methodParam.getParameterAnnotations()[0]);

Perhaps we can use the findMappingAnnotation(..) method that is already defined within that same class.

Now using findMappingAnnotation(..). The order of annotations does not matter, and the use of more than one of @Payload/@Header/@Headers on the same parameter is now checked.
