Is your feature request related to a problem? Please describe.
Based on FasterXML/jackson-module-scala#316 and some other issues that have popped up where users want to work with Map<KeyClass, ValueClass> where the KeyClass can't be readily represented as a String.
Describe the solution you'd like
Typically, Maps (eg Map(1 -> "a", 2-> "b")) are serialized as something like:
But we could have a way to annotate this Map so that it gets serialized as:
[
{
"key": 1,
"value": "a"
},
{
"key": 2,
"value": "b"
}
]
The names of the JSON elements key and value could be made configurable.
This latter serialization could allow the key value to be represented as a JSON object or array.
This serialization might be useful for someone who wanted to JSON serialize a Map as opposed to using Java serialization.
Additional context
Not urgent. Just opened as a discussion topic. Users can currently write their own custom serializers and deserializers to achieve this.
