Annotations are:

• @JsonManagedReference is the "forward" part of reference: one that gets serialized normally, and handling of which triggers back-linkage for the other reference

  • Annotated property can be a bean, array, Collection (List, Set) or Map type, and it must be a bean property (handled by a property of type serialized using BeanSerializer

• @JsonBackReference is the "back" part of reference: it will be omitted from serialization, and re-constructed during deserialization of forward reference.

  • Annotated property must be of bean type

These annotations can be used for:

* Methods (getters and setters) * Fields

but not for types (classes) or constructor arguments.

Annotations take optional "name" parameter; if omitted default name is used. Name is needed to allow multiple reference pairs for one bean type.
