The problem is mixing Spring Data Release Trains with one another.
spring-data-mongodb 1.4 is part of Release Train Codd that requies to have spring-data-commons 1.7, while spring-data-commons 1.5 which you're currently using was part of the Arora release.
So either downgrade to spring-data-mongodb 1.2 or upgrade to spring-data-commons 1.7. Maybe also have a look at your dependencies and check for potential conflicts.
Sidenote: you can checout the spring data wiki pages to see which versions have been part of a particular release.
