Hibernate persist failure with PostGIS Geometry

Question

Related to previous question. I have a Spring Roo application using Hibernate to write a Geometry object to a PostGIS database using JTS. I believe I\'ve fixed the problems

Answer 1

Yes, the ? are substituted by the values you need to store.

Did you try to use the following type: GeometryUserType and not the GeometryType? I suspect GeometryType is not directly supported by the API of Hibernate Spatial Project. It is maybe an abstract class which you could not instantiate directly to map your datas with annotations - it acts beyond the scene as we have experimented.

Caused by: java.lang.UnsupportedOperationException which has make me tell that.

And the last XML stuff inside the tutorial you have followed is clear:

Looking at the code inside the GeometryUserType I see only one place where these exception could be thrown.

public Object conv2DBGeometry(Geometry jtsGeom, Connection connection) {
        org.postgis.Geometry geom = null;
        jtsGeom = forceEmptyToGeometryCollection(jtsGeom);
        if (jtsGeom instanceof com.vividsolutions.jts.geom.Point) {
            geom = convertJTSPoint((com.vividsolutions.jts.geom.Point) jtsGeom);
        } else if (jtsGeom instanceof com.vividsolutions.jts.geom.LineString) {
            geom = convertJTSLineString((com.vividsolutions.jts.geom.LineString) jtsGeom);
        } else if (jtsGeom instanceof com.vividsolutions.jts.geom.MultiLineString) {
            geom = convertJTSMultiLineString((com.vividsolutions.jts.geom.MultiLineString) jtsGeom);
        } else if (jtsGeom instanceof com.vividsolutions.jts.geom.Polygon) {
            geom = convertJTSPolygon((com.vividsolutions.jts.geom.Polygon) jtsGeom);
        } else if (jtsGeom instanceof com.vividsolutions.jts.geom.MultiPoint) {
            geom = convertJTSMultiPoint((com.vividsolutions.jts.geom.MultiPoint) jtsGeom);
        } else if (jtsGeom instanceof com.vividsolutions.jts.geom.MultiPolygon) {
            geom = convertJTSMultiPolygon((com.vividsolutions.jts.geom.MultiPolygon) jtsGeom);
        } else if (jtsGeom instanceof com.vividsolutions.jts.geom.GeometryCollection) {
            geom = convertJTSGeometryCollection((com.vividsolutions.jts.geom.GeometryCollection) jtsGeom);
        }

        if (geom != null)
            return new PGgeometry(geom);
        else
            throw new UnsupportedOperationException("Conversion of "
                    + jtsGeom.getClass().getSimpleName()
                    + " to PGgeometry not supported");
    }

Where PGgeometry stands for PostGis Geometry I think (or maybe PostgreSQL).

I have found some topics where Karel Maesen and others speak about the InnoDB support is not very well, but they are maybe outdated (05-2011).

Good luck!
