About me

The results of poor mental health can be deadly. Globally, a man dies every minute from suicide. Men, regardless of age group, often don't recognise when they’re experiencing a mental health issue, and may not be comfortable asking for help.

Greetings, Java Hipsters

Side-by-Side Approach

@SuppressWarnings("unused")
@Repository
public interface BorrowRepository extends JpaRepository<Borrow, Long> {

}

@SuppressWarnings("unused")
@Repository
public interface BorrowRepositoryCustom extends BorrowRepository {
	
}

Side-by-Side Approach

import BookCopyService from "@/entities/book-copy/book-copy.service";

export default class BookCopyServiceCustom extends BookCopyService {
	
}

Going to Production

  • Start with less
  • Don't touch generated code
  • Keep JDL up to date
  • Use same DB in Dev & Prod
  • Integrate testcontainers
  • Use DTO & Services
  • Most likely you will add a custom web api
