@Target(value={ANNOTATION_TYPE,METHOD,FIELD}) @Retention(value=RUNTIME) public @interface JsonKey
At most one accessor of a Class
can be annotated with this annotation;
if more than one is found, an exception may be thrown.
Also, if method signature of annotated method is not compatible with Getters,
an exception may be thrown (whether exception is thrown or not is an
implementation detail (due to filtering during introspection, some annotations
may be skipped) and applications should not rely on specific behavior).
A typical usage is that of annotating toString()
method so that returned String value is used as the JSON serialization;
and if deserialization is needed, there is matching constructor
or factory method annotated with JsonCreator
annotation.
Boolean argument is only used so that sub-classes can "disable" annotation if necessary.
