Use an adapter that implements XmlAdapter for custom marshaling.

Usage:

The @XmlJavaTypeAdapter annotation can be used with the following program elements:

When @XmlJavaTypeAdapter annotation is defined on a class, it applies to all references to the class.

When @XmlJavaTypeAdapter annotation is defined at the package level it applies to all references from within the package to @XmlJavaTypeAdapter.type().

When @XmlJavaTypeAdapter annotation is defined on the field, property or parameter, then the annotation applies to the field, property or the parameter only.

A @XmlJavaTypeAdapter annotation on a field, property or parameter overrides the @XmlJavaTypeAdapter annotation associated with the class being referenced by the field, property or parameter.

A @XmlJavaTypeAdapter annotation on a class overrides the @XmlJavaTypeAdapter annotation specified at the package level for that class.

This annotation can be used with the following other annotations: XmlElement, XmlAttribute, XmlElementRef, XmlElementRefs, XmlAnyElement. This can also be used at the package level with the following annotations: XmlAccessorType, XmlSchema, XmlSchemaType, XmlSchemaTypes.

Example: See example in XmlAdapter
