You would need to annotate your data classes with Note that you can annotate regular classes as well, but there is more limitation on what is supported. Implementation ':kotlinx-serialization-runtime:0.20.0'Ĭlasspath ':kotlin-serialization:$kotlin_version'Ĭheck out the official doc for the latest runtime version. You would need to modify your adle a bit, but after that is super easy. Kotlin's own way is a compiler plugin with a runtime dependency. And Kotlin, since version 1.3, provides its own way way for serializing to and from JSON (and other formats, like protobuf - maybe in another post). There are other modern JSON libraries out there (e.g. But lately, especially with Kotlin's null-aware type system, the library fell out of grace. In the past, this used to be the Gson library. In Android (and in the Java world in general) this was traditionally 'outsourced' to a dedicated library. If you are using your own serializers module, you need to create your own KotlinSerializationJsonHttpMessageConverter object.So you want to quickly convert your Data classes to JSON and vice-versa.

Make sure that you using Spring 5.3.2 or higer versions, if you want to have both Kotlin serialization and Jackson in the classpath. If you are using Spring 5.3.1, you'll find out that Jackson will be added instead of Kotlin serialization. However, this only applies to Spring 5.3.2. This is because KotlinSerializationJsonHttpMessageConverter appears before Jackson in the list. When you have both Kotlin serialization and Jackson on the classpath, Kotlin serialization will be checked first. Private KSerializer serializer ( Type type )
