Answer 2

Using Spring Data?

No implementation needed, most of work are made transparently using proxies, and could be something like that...

@Repository
public interface FooRepository extends CrudRepository<Foo, Long> {
.....
}

or extends from

PagingAndSortingRepository<Foo, Long>

if need extra support pagination/sorting in findAll methods.

NOTE: Long is the type of the Entity property annotated with @ID (a.k.a Primary Key)

Take a look at reference documentation:

CORE:
https://docs.spring.io/spring-data/commons/docs/current/reference/html/

JDBC:
https://docs.spring.io/spring-data/jdbc/docs/current/reference/html/

JPA:

Answer 3

With Spring, no implementation class is needed. The Framework is in charge of, following a simple rules, transform method names to sql/jqj... using configured dialect through proxies
