Not retrieving appropriate SRID in PostgisDataStore.createSchema
----------------------------------------------------------------
Key: GEOT-2189
URL: http://jira.codehaus.org/browse/GEOT-2189
Project: GeoTools
Issue Type: Bug
Components: data postgis
Affects Versions: 2.5.1, 2.5.0
Reporter: Milton Jonathan
Assignee: Justin Deoliveira
Priority: Minor
Fix For: 2.5.1, 2.5.0
Attachments: geotools-tecgraf.2.5.x.postgis_getsrid.patch
Whenever PostgisDataStore.createSchema(featureType) is called, it retrieves the
CoordinateReferenceSystem from the provided FeatureType and must find a
suitable corresponding SRID for creating the schema correctly in Postgis.
However, this method was only working for CRS's that do not have identifiers,
which is a problem when one is reading them from WKTs such as those coming from
shapefile .prj files.
The problem was corrected by calling CRS.lookupIdentifier() if needed. A test
and patch is provided for that. Two things to notice are:
- The code for retrieving the SRID was separated from the createSchema method,
in order to allow it to be tested
- The pom.xml file for the Postgis module was changed to include epsg-hsql,
since that is required for CRS.lookupIdentifier to work properly.
