I'm using ObjectMapper to serialize an object containing a map so that the corresponding serialized json text have an array instead of the map.

- First, I have a problem with JsonTypeInfo. It is not serialized in the json text but it is when I don't use my custom serializer (map -> array)

- An other problem, is that I don't know how to write the custom deserializer to deserialize the array to map.

I have write an example project available here : GitHub - mike03081972/sortedmaptest[^]

Normal serializer/deserializer can be tested with : Tests.serializeDeserializeTest

Custom serializer can be tested with : Tests.customSerializeTest

What I have tried:

google search :
java - Deserialize JSON array to Map using Jackson - Stack Overflow[^]

Solution found for the second point : write custom deserializer

But nothing found for the first problem regarding the JsonTypeInfo
