intermediateSpring Boot with MongoDB — Spring Data MongoDB & MongoRepository
How does Spring Data MongoDB generate a working repository implementation when you only write an interface?
At startup, Spring scans for interfaces extending MongoRepository and creates a dynamic proxy implementing it. Method calls on the proxy are intercepted — for derived-query methods, the method name itself is tokenized into field/operator/connector pieces and translated into an actual MongoDB query, executed via the underlying MongoTemplate.
