Class JsonConverter

java.lang.Object

org.javers.core.json.JsonConverter

public class JsonConverter
extends Object

Javers is meant to support various persistence stores for any kind of client's data, hence we use JSON format to serialize/deserialize client's domain objects.

Javers uses Gson library which provides neat and pretty JSON representation for well known Java types.

But sometimes Gson's default JSON representation isn't appropriate for your domain model. This is often the case when dealing with Values like Date or Money.

If so, you can easily customize Javers serialization/deserialization behaviour by providing plugins for each of your custom type. Javers accepts several kind of plugins:

• BasicStringTypeAdapter - extend it if you need to represent unwrap as single String and don't want to deal with JSON API. For concrete class example see LocalDateTimeTypeAdapter.
• JsonTypeAdapter - use it if you need full control over JSON conversion
• native Gson TypeAdapter
• native Gson JsonSerializer
• native Gson JsonDeserializer

Javers provides JsonTypeAdapter's for some well known Value like LocalDateTime. Those adapters are included by default in Javers setup, see JsonConverterBuilder.BUILT_IN_ADAPTERS
