Stores (and Repositories) are arranged in a separate "module" from the SpringBootApplication context.
To run:
$ cd issue-33
$ mvn clean install
$ java -jar parent/target/parent-0.0.1-SNAPSHOT.jar
In your browser visit http://localhost:8080/index.html where you should be presented with a simple file list with upload. Stateful as long as the application is running. Proves JPA repositories and stores can be found by the spring application context even if arranged into separate modules.
