Document

Method for enabling automatic inclusion of type information -- needed for proper deserialization of polymorphic types (unless types have been annotated with com.fasterxml.jackson.annotation.JsonTypeInfo ) -- using "As.PROPERTY" inclusion mechanism and specified property name to use for inclusion (default being "@class" since default type information always uses class name as type identifier)

Usage

From source file:org.nohope.jongo.JacksonProcessor.java

@Nonnull
private static ObjectMapper createPreConfiguredMapper() {
    final ObjectMapper mapper = new ObjectMapper();
    mapper.registerModule(new JodaModule());
    mapper.registerModule(new ColorModule());

    mapper.configure(FAIL_ON_UNKNOWN_PROPERTIES, false);
    mapper.configure(AUTO_DETECT_GETTERS, false);
    mapper.configure(AUTO_DETECT_SETTERS, false);
    mapper.setSerializationInclusion(NON_NULL);
    mapper.setVisibilityChecker(VisibilityChecker.Std.defaultInstance().withFieldVisibility(ANY));

    mapper.enableDefaultTypingAsProperty(ObjectMapper.DefaultTyping.NON_FINAL,
            JsonTypeInfo.Id.CLASS.getDefaultPropertyName());

    final SimpleModule module = new SimpleModule("jongo", Version.unknownVersion());
    module.addKeySerializer(Object.class, ComplexKeySerializer.S_OBJECT);
    module.addKeyDeserializer(String.class, ComplexKeyDeserializer.S_OBJECT);
    module.addKeyDeserializer(Object.class, ComplexKeyDeserializer.S_OBJECT);

    //addBSONTypeSerializers(module);

    mapper.registerModule(module);/*from   w w  w  .  j  a v  a 2 s . c  o m*/
    return mapper;
}
