ObjectMapper (jackson-databind 2.7.0 API)
ObjectMapper provides functionality for reading and writing JSON, either to and from basic POJOs (Plain Old Java Objects), or to and from a general-purpose JSON Tree Model (JsonNode), as well as related functionality for performing conversions. It is also highly customizable to work both with different styles of JSON content, and to support more advanced Object concepts such as polymorphism and Object identity.

Intro to the Jackson ObjectMapper | Baeldung
December 9, 2025 - String json = "{ \"color\" : \"Black\", \"type\" : \"BMW\" }"; Map<String, Object> map = objectMapper.readValue(json, new TypeReference<Map<String,Object>>(){}); One of the greatest strengths of the Jackson library is the highly customizable serialization and deserialization process.

Jackson, moshi or kotlinx.serialization?

Kotlinx serialization is so elegant and nice, I really love it. I love it so much that I spent some time on making toml serialization library based on it: https://github.com/akuleshov7/ktoml

2 weeks ago - These extensions are plug-in Jackson Modules (registered with ObjectMapper.registerModule()), and add support for datatypes of various commonly used Java libraries, by adding serializers and deserializers so that Jackson databind package (ObjectMapper / ObjectReader / ObjectWriter) can read and write these types.

Mapper Features · FasterXML/jackson-databind Wiki · GitHub
Jackson defines a set of per-mapper configuration, which can ONLY be defined before using ObjectMapper -- meaning that these settings can not be changed on-the-fly, on per-request basis. They configure fundamental POJO introspection details, and resulting built objects (serializers, deserializers, related) are heavily cached.
