Use a Java5 enum as @Embeddable

Hi,

I need to store some enum in database, but can't use either the ordinal nor the enum "constant" name. I need to use a value passed to the enum in constructor that is used internally :

public enum Acte
{
ACHAT( 10 ),
ACTIVATION( 2 ),
ANNULATION( 8 )
...
}

I'd like to use such enum class as JPA @Embeddable.
Is this possible ? Maybe there is some
Hibernate non-JPA support for such use case ?

Thanks for any suggestion.

As a side note, the question could be :
"is there any way to define a global Type Converter in Hibernate ?"

I'd like to avoid to annotate all my enums with a @Type.

How about converting the internal value in your entity:

Code:

@Entity 
public class YourEntity {
   ...
   //avoid that hibernate stores the enum
   @Transient
   public Acte getActe(){...}
   ...
   //private getter, only used by hibernate
   private Integer getActeInternal(){
     //return the inner value here
   }
    
   private void setActeInternal() {
     // do your conversion here
   }
}

It's even more intrusing than some @Type annotation

@Type seems to be the simpliest solution in my case
