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

It seems the problem was that the PostgisDialect was not been picked up and integrated correctly, and hence the required operations were not supported. The solution was as simple as upgrading from Hibernate 3.6.9.Final to 4.1.6.Final!

See my thread on the mailing list for more information.

As per that thread, you should also be aware that as of Hibernate Spatial 4.0-M1, only the Geometry type is specified to Hibernate, and hence the @Column annotation must set columnDefinition="Geometry", and not Point or anything else. This may be fixed in the future.

With this anthology of modifications, I can finally write a Point to a database! The correct property specification is:

@Column(columnDefinition="Geometry")
@Type(type = "org.hibernate.spatial.GeometryType")
private Point centerPoint;
