A project with spring-data-mongodb supporting multi tenancy

If you are having a structure like the following in your mongodb it is pretty bad to handle, since spring-data-mongodb does not support multi tenancy.

CUSTOMER_DB_A #
  - collectionA
  - collectionB
  - collectionC
CUSTOMER_DB_B
  - collectionA
  - collectionB
  - collectionC

the data structure in these collections is the same, every customer does just have its own database in one mongodb instance.

There are serveral requests on StackOverflow regarding this topic: http://stackoverflow.com/questions/16325606/making-spring-data-mongodb-multi-tenant http://stackoverflow.com/questions/20791656/multi-tenant-mongodb-database-based-with-spring-data http://stackoverflow.com/questions/12078669/spring-data-mongodb-connect-to-multiple-databases-in-one-mongo-instance

I don't think that this is the best approach to archive this functionality but it just works without reinventing spring-data-mongodb.

With just a ThreadLocal it is not done, if you walso want to create Indexes. So I added a bit more sugar to it.

Just take a look into Application.java

Happy Hacking!
