Michael Rüegg created OPENJPA-2341:
--------------------------------------
Summary: OpenJPA ignores custom field strategies globally defined
in persistence.xml
Key: OPENJPA-2341
URL: https://issues.apache.org/jira/browse/OPENJPA-2341
Project: OpenJPA
Issue Type: Bug
Affects Versions: 2.2.0
Reporter: Michael Rüegg
I use a custom field strategy value handler (a class that extends
org.apache.openjpa.jdbc.meta.strats.AbstractValueHandler) for my entities that
make use of joda time fields:
@Entity
public class MyEntity {
org.joda.time.LocalDateTime creationDate;
}
When I use the inline strategy annotation
(@Strategy("com.xyz.LocalDateValueHandler")), everything works as expected and
my LocalDateTime field 'creationDate' gets mapped to an SQL timestamp. However,
if I reference my value handler globally in the persistence.xml file, then
OpenJPA is not able to find the value handler (i.e., it is never called), which
results in a blob column type for 'creationDate'. Here's the corresponding
snippet from my persistence.xml:
<property name="openjpa.jdbc.MappingDefaults"
value="FieldStrategies='org.joda.time.LocalDateTime=com.xyz.LocalDateValueHandler"/>
Note that if I use a mapping from a standard JDK class like java.lang.String to
my value handler, then my handler is called as expected. Is this issue somehow
related to #OPENJPA-758? Note that I use Derby as my database.
Any help would be much appreciated.
