@CompileStatic
class EssentialJacksonCustomizer
extends Object
implements Jackson2ObjectMapperBuilderCustomizer, BeanPostProcessor

Implementation of Spring Boot's Jackson2ObjectMapperBuilderCustomizer which configures Spring Boot's provided com.fasterxml.jackson.databind.ObjectMapper with a set of essential options.

So called 'essential' options are completely opinionated, of course, but they proven to be very useful base in many internal projects. If one finds some, or all of them, not appropriate, they can be turned off via EssentialJacksonCustomizerConfigurationProperties configuration properties.

Beside Jackson configuration options available here, Spring Boot default options from JacksonAutoConfiguration still apply. Namely these are SerializationFeature.WRITE_DATES_AS_TIMESTAMPS = false and SerializationFeature.WRITE_DURATIONS_AS_TIMESTAMPS = false.

EssentialJacksonCustomizer configures following defaults:

• transient fields and properties are ignored for de/serialization (MapperFeature.PROPAGATE_TRANSIENT_MARKER = true)
• read-only (a.k.a. getter-only or derived) properties are ignored for de/serialization (MapperFeature.REQUIRE_SETTERS_FOR_GETTERS = true)
• enum names are case-insensitive for deserialization (MapperFeature.ACCEPT_CASE_INSENSITIVE_ENUMS = true)
• serialization - adds GStringSerializer and UomQuantitySerializer serializers
• serialization - null values are skipped (serializationInclusion = JsonInclude.Include.NON_NULL)
• deserialization - adds StringSanitizingDeserializer and UomQuantityDeserializer deserializers
• deserialization - json comments are allowed (JsonParser.Feature.ALLOW_COMMENTS = true)
• deserialization - single values are accepted into array (DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY = true)
• deserialization - failing on unknown properties is disabled (DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES = false)
• deserialization - null values are skipped (defaultSetterInfo = JsonSetter.Value.forValueNulls(Nulls.SKIP))
