Subtype Discovery Module for Jackson FasterXML

If a class model contains a inheritance tree where sub types may not be known or cannot be added to the base class using the @JsonSubTypes annotation (e.g. spread out over multiple jar files), the object mapper will not be able to figure out what contrete class is required when deserialising JSON content. This module can be used to register unknown subtypes with a Jackson object mapper.

The concrete class just needs to have a @JsonTypeName annotation at the class level and the contrete or base class has to carry the @JsonTypeInfo annotation with appropriate configuration. Alternatively one can also register a mixin class with

Basic use case:

private ObjectMapper mapper;
mapper.registerModule(new SubtypeDiscoveryModule("zoo"));
  
// mapping activities

Please refer to the zoo.ZooTest for some examples on how to use sub typeing and this module.
