- Jackson custom deserializer abstract class. Few lines above, we exposed our abstraction of Player. Yes, you can write your own Custom Deserializer for the abstract class. This class extends StdDeserializer and overrides the deserialize () method. As. PROPERTY, property = "request_name") Sep 1, 2022 · In this Jackson tutorial, we learned to create custom Jackson serializers and deserializers. To implement a custom deserializer, we need to create an implementation of StdDeserializer which is an abstract type and the base class for common Jackson deserializers. There is likely a more idiomatic way of doing this, but here is a quick-and-dirty example: public static void main(String args) throws IOException { See full list on baeldung. May 20, 2015 · As for the creation of a custom serializer Jackson supply us for extension the class StdSerializer, similarly to define a relavant custom deserializer we can start with the extension of the StdDeserializer class, implementing the deserialize () method it inherits from the JsonDeserializer abstract class. NAME, include = JsonTypeInfo. Aug 28, 2017 · The object itself has multiple attributes that are complex datatypes themselves. Jackson provides the abstract class TypeReference to obtain the type information from the derivated subclasses: public abstract class TypeReference <T> { Apr 9, 2019 · Jackson provides JsonDeserializer and its subclasses such as StdDeserializer to deserialize objects from JSON. This deserializer will have to determine which concrete class the JSON represents, and instantiate an instance of it. I am actually working with Kotlin and wanted to custom deserialize just one attribute of my class and none of the answers helped me ( I was able to write a custom one for the whole class but not just for one attribute ). According to Jackson, we should extend StdDeserializer or its subtypes like StdScalarDeserializer class to create custom deserializer instead of using JsonDeserializer abstract class. Hovewer some of the attributes belong to different subclasses of an abstract super-class, which themselves have attributes that are subclasses of a different abstract super-class. com If you want to serialize or deserialize a domain type in a special way, you can register your own implementations with Jackson’s ObjectMapper.

Jun 25, 2025 · As well known, Java erases generic type information during compilation, but we can take advantage of the power of anonymous inner classes to preserve the type information during compile time. Most of them can be serialized just fine by the standard Jackson deserializer.
