Is it possible to add filed to Enum and use it instead of the ordinal?
Example:

Code:

public enum RuleType {
      FIRST_RULE(10),
      SECOND_RULE(20);
 
int myFiled;
RuleType(int i){
   myFiled=i;
}
}
 

So I can use myFiled with the ruleType filed ?

Code:

 
@Enumerated(EnumType.ORDINAL)
@Column(name="RULE_TYPE")
public RuleType getRuleType() {
   return ruleType;
}

I was looking for something like this and it seems that writing a user type is still the only way to go. I was hopping that by now we would have a more elegant solution for a so common use case.

Using ordinal values is very brittle and using String most of the times is not possible with legacy databases.
