Marks a Map property on a bean that unmapped JSON properties go into.


This property is considered transient (not mapped to a DB column) unlike @DbJson but will be
written to JSON output (unless it also annotated with @JsonIgnore).




Being JSON read and written means that in a document store only (ElasticSearch only) case it can hold
all top level unmapped properties.



Example:



 @UnmappedJson Map unmapped;
}
