relationship ManyToOne {
  Blog{user(login)} to User,
  Post{blog(name)} to Blog
}

relationship ManyToMany {
  Post{tag(name)} to Tag{post}
}

paginate Post, Tag with infinite-scroll
paginate Product with pagination

microservice Product with store
microservice Blog, Post, Tag with blog

1. Create an apps.jh file with the JDL above, then run jhipster import-jdl apps.jh.

2. Docker commands you need to run before starting each app:

docker-compose -f gateway/src/main/docker/jhipster-registry.yml up -d
docker-compose -f gateway/src/main/docker/keycloak.yml up -d
docker-compose -f store/src/main/docker/mongodb.yml up -d

3. Then run ./mvnw in each application's directory.
4. Open your browser to http://localhost:8080 and login.

Thank you very much for your great tutorials!!!!

It's my pleasure! 😊
