jooq-postgis-spatial

jOOQ data type converters and binders for PostGIS spatial database. Project inspired and uses some Hibernate Spatial classes to convert org.postgresql.util.PGobject geometry to JTS geometry. The similar project for MySQL spatial can be found here: jooq-mysql-spatial

Writing JTS geometries

Point point = JTS.getDefaultGeomFactory().createPoint(new Coordinate(...))
dsl.insertInto(CITY, CITY.ID, CITY.NAME, CITY.GEOM)
        .values(1, "Lyon", point)
        .execute();

Reading JTS geometries

Point point = (Point) dsl.select(CITY.GEOM)
        .from(CITY)
        .where(CITY.ID.eq(1))
        .fetchOne(CITY.GEOM);

Querying

Search cities located in France

Polygon france = JTS.getDefaultGeomFactory().createPolygon(...)
Result<CityRecord> cities = dsl.selectFrom(CITY)
        .where(MBRWithin(CITY.GEOM, france))
        .fetch();

Search to country containing Lyon

Point lyon = JTS.getDefaultGeomFactory().createPoint(new Coordinate(...))
Result<CountryRecord> countries = dsl.selectFrom(COUNTRY)
        .where(MBRContains(COUNTRY.GEOM, lyon))
        .fetch();

TODO

Define spatial functions like ST_Intersects , ST_CoveredBy, ST_Within etc.
