Mapping Enums
Java enums can be mapped to XML using the @XmlEnum and @XmlEnumValue annotations.
Mapping enum constant name
If your enums constant names themselves are sufficient for the XML representation, you can simply use the @XmlEnum annotation:
@XmlEnum public enum Card { CLUBS, DIAMONDS, HEARTS, SPADES }
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>
