Mapping Enums
Java enums can be mapped to XML using the @XmlEnum and @XmlEnumValue annotations.
Mapping enum constant name
The following schema demonstrates an XML enumeration:
<xs:simpleType name="CustomerType"> <xs:restriction base="xs:string"/> <xs:enumeration value="PROMO_CUSTOMER"/> <xs:enumeration value="NEW_CUSTOMER"/> <xs:enumeration value="VIP"/> <xs:enumeration value="NORMAL"/> </xs:simpleType>
If your enums constant names themselves are sufficient for the XML representation, you can simply use the @XmlEnum annotation:
@XmlAccessorType(XmlAccessType.FIELD) public class Customer { @XmlElement(name="type") private CustomerType type = CustomerType.NEW_CUSTOMER; ... @XmlEnum public enum CustomerType { PROMO_CUSTOMER, NEW_CUSTOMER, VIP, NORMAL } } @XmlEnum public enum CustomerType { PROMO_CUSTOMER, NEW_CUSTOMER, VIP, NORMAL }
When marshalled to XML, an Person would look like this:
<xs:simpleType name="Card"> <xs:restriction base="xs:string"/> <xs:enumeration value="CLUBS"/> <xs:enumeration value="DIAMONDS"/> <xs:enumeration value="HEARTS"/> <xs:enumeration value="SPADES"/> </xs:simpleType>
Mapping enum constant name(value)
This code:
@XmlType @XmlEnum(Integer.class) public enum Coin { @XmlEnumValue("1") PENNY(1), @XmlEnumValue("5") NICKEL(5), @XmlEnumValue("10") DIME(10), @XmlEnumValue("25") QUARTER(25) }
will generate the following XML schema:
<xs:simpleType name="Coin"> <xs:restriction base="xs:int"> <xs:enumeration value="1"/> <xs:enumeration value="5"/> <xs:enumeration value="10"/> <xs:enumeration value="25"/> </xs:restriction> </xs:simpleType>
