@Target(value={METHOD,FIELD}) @Retention(value=RUNTIME) public @interface XmlKey
XmlKey is used to mark a property as a key, to be referenced using a key-based mapping via XmlJoinNode. This is
similar to the XmlID annotation, but doesn't require the property be bound to the schema type ID. XmlKey is
typically used in the composite key use case, since only 1 property can be annotated with the XmlID annotation.
Example:
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Employee {
@XmlKey
public String id;
@XmlKey
public String department;
@XmlJoinNodes({
@XmlJoinNode(xmlPath="manager/id/text()", referencedXmlPath="id/text()"),
@XmlJoinNode(xmlPath="manager/dept/text()", referencedXmlPath="department/text()")
})
public Employee manager;
}
