Mastering Spring 5.0

The CrudRepository interface

We can extend CrudRepository to expose all create, read, update, and delete methods on an entity. The following snippet shows TodoRepository extending CrudRepository:

    public interface TodoRepository extends CrudRepository<Todo, Long>     {    }

TodoRepository can be used to perform all methods exposed by the CrudRepository interface. Let's write a few unit tests to test some of these methods.
