General-purpose annotation used for configuring details of how values of properties are to be serialized. Unlike most other Jackson annotations, annotation does not have specific universal interpretation: instead, effect depends on datatype of property being annotated (or more specifically, deserializer and serializer being used).

Common uses include choosing between alternate representations -- for example, whether Date is to be serialized as number (Java timestamp) or String (such as ISO-8601 compatible time value) -- as well as configuring exact details with pattern property.

As of Jackson 2.6, known special handling includes:

  • Date: Shape can be Shape.STRING or Shape.NUMBER; pattern may contain SimpleDateFormat-compatible pattern definition.
  • Can be used on Classes (types) as well, for modified default behavior, possibly overridden by per-property annotation
  • Enums: Shapes Shape.STRING and Shape.NUMBER can be used to change between numeric (index) and textual (name or toString()); but it is also possible to use Shape.OBJECT to serialize (but not deserialize) Enums as JSON Objects (as if they were POJOs). NOTE: serialization as JSON Object only works with class annotation; will not work as per-property annotation.
  • Collections can be serialized as (and deserialized from) JSON Objects, if Shape.OBJECT is used. NOTE: can ONLY be used as class annotation; will not work as per-property annotation.
  • Number subclasses can be serialized as full objects if Shape.OBJECT is used. Otherwise the default behavior of serializing to a scalar number value will be preferred. NOTE: can ONLY be used as class annotation; will not work as per-property annotation.
