Greetings, Java Hipsters


How long does it take to setup a modern web application?

How long does it take to configure databases, security, api?

How long does it take to go to production?

What is JHipster?

Gettin' Started

The real java hipster

Side-by-Side Approach

public interface BorrowRepository extends JpaRepository<Borrow, Long> {


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

create application via jdl

What else?

  • Kotlin Blueprint
  • Node Blueprint
  • .net Blueprint
  • Quarkus/Micronaut Blueprint
  • Spring Boot 2.2
  • Neo4J Support
  • Modulith
