Question:
I have a Entity with a field which I want to be an Enum.
@Column(name = "TEMPRATURE_ZONE") @Enumerated(STRING) private TemperatureRegime tempratureZone; The Enum is defined as follows:
public enum TemperatureRegime { AMBIENT, CHILL } The data in my table for this field is always "AMBIENT" or "CHILL" yet when I do a findAll query on the table I am getting the following exception:
Exception [EclipseLink-116] (Eclipse Persistence Services - 2.1.0.v20100614-r7608): org.eclipse.persistence.exceptions.DescriptorException Exception Description: No conversion value provided for the value [Chill] in field [LOCATION_GROUP.TEMPRATURE_ZONE]. Mapping: org.eclipse.persistence.mappings.DirectToFieldMapping[tempratureZone-->LOCATION_GROUP.TEMPRATURE_ZONE] Descriptor: RelationalDescriptor(com.company.location.LocationGroup --> [DatabaseTable(LOCATION_GROUP)]) I can't see what the problem is, any ideas?
Cheers,
James
Solution:1
I believe this is simply a case issue. Your enum defines CHILL while the database value is Chill. The simplest solution should be to change the enum definition to match the database values.
Alternatively I documented a converter approach to handle the database strings not matching the enum values exactly:
