Here is an example:

@Entity
public class EntityA  {
    @Id private int id;
    @Enumerated( EnumType.ORDINAL )
    private Measure measure;
   =20
    public Measure getMeasure() {
        return measure;
    }
   =20
    public void setMeasure(Measure measure) {
        this.measure =3D measure;
    }
=09
    public int getId() {
=09return id;
    }
=09
    public void setId(int id) {
=09this.id =3D id;
    }
}

public enum Measure  {
    M1 ("M1", false),
    M2 ("M2", false),
    M3 ("M3", false),
    M4 ("M4", false),
    M5 ("M5", true);
  =20
    private String description;
    private Measure(String desc){
        this.description=3Ddesc;
    }
    public String desc(){return this.description;}
}
