Re: [eclipselink-users] @MappedSuperclass and @Embeddable

[Guy Pelletier <guy.pelletier@xxxxxxxxxx>]

We currently do not support Embedabble's inheriting from a MappedSuperclass.

Please vote for the following bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=283028

You can move the @StructConverter definition down to the Embeddable (or some other class) and then add a descriptor customizer to map Basic geometry mapping there, something along the lines of:

DirectToFieldMapping mapping = new DirectToFieldMapping();
mapping.setAttributeName("geometry");
mapping.setGetMethodName("getGeometry");
mapping.setSetMethodName("setGeometry");
mapping.setFieldType(Types.STRUCT);

DatabaseField field = new DatabaseField();
field.setName(""geometry");
field.setColumnDefinition("MDSYS.SDO_GEOMETRY");
mapping.setField(field);

descriptor.addMapping(mapping);

Cheers,
Guy

Hi.

I have this:

@MappedSuperclass

@Access(AccessType.PROPERTY)

@StructConverter(name = "JGeometryConverter", converter = "se.lantmateriet.origo.domain.model.geometry.OracleGeometryConverter")

public class Point extends FeatureGeometry {

    @Convert("JGeometryConverter")

    @Column(name = "geometry", columnDefinition = "MDSYS.SDO_GEOMETRY")

    public OracleGeometry getGeometry() {

        return this.position.getGeometry();

    }

    protected void setGeometry(final OracleGeometry oracleGeometry) {

        double[] pointCoordinate = oracleGeometry.getGeometry().getFirstPoint();

        this.position = POSITION(N(pointCoordinate[1]), E(pointCoordinate[0]));

    }

}

@Embeddable

public class GeographicLocation extends se.lantmateriet.origo.domain.model.geometry.Point {}

How can GeographicLocation "see" and map geometry from the inherited class? I guess I need some customizer, but what should I put there?
