Configure own messageSource with spring-boot

Question

I'm using spring-boot and was using the MessageSourceAutoConfiguration but now for the messageSource I want to define a parentMessageSource using a ResourceBundleMessageSource. However, I can't see how to do this with boot's auto configuration. I've tried excluding the MessageSourceAutoConfiguration.class but am getting the exception below when trying to define my own messageSource bean
any help greatly would be appreciated.

I had both the 'messageSource' and 'parentMessageSource' @Bean's defined in a WebFlowConfig @Configuration class. I moved these two @Bean's to their own MessageConfig @Configuration class and everything worked! My inspiration came from a similar issue here: How do I add method based security to a Spring Boot project? with explanation:

"Try putting the..." {insert your bean/s here} "...in a separate @Configuration class. You appear to be forcing it to be instantiated before the ServletContext is ready..."

Configure own messageSource with spring-boot
