Persist raw Java Enum using Hibernate

Question

I have an entity that contains an enum property. That property can be any one of my types of Enums in my codebase:

public enum AutomobileType {
   CAR, TRUCK, MOTORCYCLE
}

public enum BoatType {
   ROW_BOAT,YACHT,SHIP
}

@Entity
public class FooBar {

  @Enumerated(value=EnumType.ORDINAL)
  private Enum enumValue;

  public void setEnumValue(Enum value) { ... }
  public Enum getEnumValue() { ... }
}

This fails with an exception, "Wrong data type: For input string: "[B@f0569a". I changed FooBar to store the property as an Integer which works, but that's not what I need. I need the actual enum. Any suggestions on how to make this work so that the Enum can be persisted as int but later pulled out into the correct Enum type?

You need to define a custom UserType for the Enum.
