Hi
I am trying to use enum type in one of my entities, but when I try to get the object, Hibnernate tells me there is an unknown name value for the enum type. Please help. Thanks.
Code:
@Entity
public class CreditCard {
@Enumerated(EnumType.STRING)
@Column(name = "type", nullable = false)
private CreditCardType type;
...
}
Code:
public enum CreditCardType {
MASTERCARD("Mastercard"),
VISA("Visa"),
AMEX("American Express");
private final String cardType;
private CreditCardType(String cardType) {
this.cardType = cardType;
}
public String toString() {
return cardType;
}
}
Hibernate version: 3.2.3.ga
Name and version of the database you are using: PostgreSQL 8.2
