Manuel Blechschmidt commented on OLINGO-605:
--------------------------------------------
[~mirbo] thanks a lot.
> Olingo should support custom types e.g. Geometry by using XmlAdapter from JaxB

> Key: OLINGO-605
> URL: https://issues.apache.org/jira/browse/OLINGO-605
> Project: Olingo
> Issue Type: New Feature
> Components: odata2-jpa
> Affects Versions: V2 2.0.3
> Reporter: Manuel Blechschmidt
> Assignee: Michael Bolz
> Priority: Minor
> Labels: GIS, custom, spatial, types
> Fix For: V2 2.0.10
>
>
> I am currently developing a software where I save GIS coordinates as part of
> my entities. I want to send these geometries as a string through OData to a
> client.
> Technically I do the following:
> OpenGis -> Hibernate Spatial -> JPA -> Olingo -> JavaScript -> OpenLayers
> I already have an XmlAdapter that maps my Geometry to WKT. I want to use this
> as well for Olingo serialization
> I copied the following file in my workspace and extended the
> convertToEdmSimpleType function:
> org.apache.olingo.odata2.jpa.processor.core.access.model.JPATypeConvertor
> {code:java}
> public static EdmSimpleTypeKind
> ...
> } else if(jpaType.equals(Geometry.class)) {
> // "OData - JPA Type Converter: Type [class
> com.vividsolutions.jts.geom.Geometry] not supported"
> return EdmSimpleTypeKind.String;
> }
> throw
> ODataJPAModelException.throwException(ODataJPAModelException.TYPE_NOT_SUPPORTED
> .addContent(jpaType.toString()), null);
> }
> {code}
> This is quick and dirty and it would be nice if there would be a cleaner
> solution to do so.
