The scheduling guide isn't a web app so you probably have some mouldy stuff in your pom.xml from the REST guide? If you follow the instructions closely it should work. Another potential issue with the code you posted above is that your @EnableAutoConfiguration class is not used in the context, only as a main method (which may not be a problem for the scheduling guide but it probably is for a bunch of others).
