Stalactite ORM 1.0.0 is out !

After many years of dev, Stalactite ORM is finally released ! It has a brand new approach about persistence :

mapping is defined by method references instead of Annotations or XML
its fluent API helps you see the complexity of you graph
it eagerly fetches your relations to avoid hidden sql queries

Here is a short view of what can be achieved with it :

DataSource dataSource = ... // use whatever JDBC DataSource you want
PersistenceContext persistenceContext = new PersistenceContext(dataSource, new HSQLDBDialect());

EntityPersister<Country, Long> countryPersister = MappingEase.entityBuilder(Country.class, long.class)
    .mapKey(Country::getId, IdentifierPolicy.afterInsert())
    .map(Country::getName)
    .map(Country::getDescription)
    .mapOneToOne(Country::getPresident, MappingEase.entityBuilder(Person.class, long.class)
        .mapKey(Person::getId, IdentifierPolicy.afterInsert())
        .map(Person::getName))
    .build(persistenceContext);

Country country = new Country(42L);
country.setPresident(new Person(12L));
countryPersister.persist(country);

// you can also map an SQL query to build a projection
List<Car> allCars = persistenceContext.newQuery("select id, model, rgb from Car", Car.class)
    .mapKey(Car::new, "id", long.class)
    .map("model", Car::setModel)
    .map("rgb", Car::setColor, int.class, Color::new)
    .execute();

Give it a try, see documentation here
