#####3- Create 3layer-settings.yml in your resource folder. Example of 3layer-setting.yml :

projectPath: /home/tano/workspace_autogenerate/springboot-3layer-generator
outputDirectory : /src/main/java
options:
    dtoLayer : true

inputPackages:
    jpaEntities : com.gae.piaz.autogen.model

outputPackages:
    repositories : com.gae.piaz.autogen.repositorygen
    services: com.gae.piaz.autogen.servicegen
    controllers: com.gae.piaz.autogen.controllergen

#####4- run

gradlew layer3gen

Example:

Checkout the example project present in /demo folder.

Repository generated example class:

@Repository
public interface BooksRepository extends JpaRepository<Books, java.lang.Integer> {

}

Service generated example class:

@Service
public class BooksService implements CrudService<Books,java.lang.Integer> {

    @Autowired
    private BooksRepository repository;

    @Override
    public Books create(Books entity) {
        return repository.save(entity);
    }

    @Override
    public Books update(Books entity) {
        return repository.save(entity);
    }

    @Override
    public Page<Books> read(Books entity, Pageable pageable) {
        Example<Books> example = Example.of(entity);
        return repository.findAll(example,pageable);
    }

    @Override
    public Books readOne(java.lang.Integer primaryKey) {
        return repository.getOne(primaryKey);
    }

    @Override
    public void delete(java.lang.Integer primaryKey) {
        repository.deleteById(primaryKey);
    }
}

Controller generated example class:

@RestController

public class BooksControllerDTO implements CrudController<BooksDTO,java.lang.Integer>{

    @Autowired
