public class ObjectMapperFactory
extends Object

A generic factory to create instances of a Jackson ObjectMapper. It allows to configure the ObjectMapper for polymorphic transfer-objects.

Method Detail

getExtensionModule

public com.fasterxml.jackson.databind.module.SimpleModule getExtensionModule()

Gets access to a generic extension module for customizations to Jackson JSON mapping.

Returns:

extensionModule

See Also:

SimpleModule.addSerializer(Class, com.fasterxml.jackson.databind.JsonSerializer), SimpleModule.addDeserializer(Class, com.fasterxml.jackson.databind.JsonDeserializer)

setBaseClasses

public void setBaseClasses(Class<?>... baseClasses)

Parameters:

baseClasses - are the base classes that are polymorphic (e.g. abstract transfer-object classes that have sub-types). You also need to register all sub-types of these polymorphic classes via setSubtypes(NamedType...).

addBaseClasses

public void addBaseClasses(Class<?>... baseClasses)

Parameters:

baseClasses - the base-classes to add to base classes list.

See Also:

setBaseClasses(Class...)

setSubtypeList

public void setSubtypeList(List<com.fasterxml.jackson.databind.jsontype.NamedType> subtypeList)

Parameters:

subtypeList - the List of NamedTypes to register the subtypes.

See Also:

setSubtypes(NamedType...)

addSubtypes

public void addSubtypes(com.fasterxml.jackson.databind.jsontype.NamedType... subtypes)

Parameters:

subtypes - the NamedTypes to add to sub-type list for registration.

See Also:

setSubtypes(NamedType...)

setSubtypes

public void setSubtypes(com.fasterxml.jackson.databind.jsontype.NamedType... subtypeList)

Parameters:

subtypeList - the NamedTypes as pair of Class reflecting a polymorphic sub-type together with its unique name in JSON format.

createInstance

public com.fasterxml.jackson.databind.ObjectMapper createInstance()

Returns:

an instance of ObjectMapper configured for polymorphic resolution.

initMapping

protected com.fasterxml.jackson.databind.module.SimpleModule initMapping()

Returns:

an instance of SimpleModule for registering configurations
