spring-data-jdbc-repository implementation

[bwajtr]

Not sure if it makes sense to do implementation using this library, but we should at least check it:

Not sure if this is the same thing as mentioned repository, but it seems that Spring made Spring Data JDBC an official approach:
https://spring.io/blog/2018/09/17/introducing-spring-data-jdbc

So we should add implementation of it...

These two are different things.

Let me know if you need help with the second one.
