Question

Is it possible to serialize/deserialize Map where type of object (mapped value) would be determined by its key.

Answer 1

Yes, it could be done. Have another structure that contains a pair of Map<String, Class> and link the key name of the first structure (Map<String, Object>) to the second one.

For example

Map map = new HashMap<String, Object>();`

map.put("desc", "something really important");

Map deser = new HashMap<String, Class>();

deser.put("desc", StringDeserializer.class);

You could also use a deser<String, String>, where the value would be the class name, then you just do a class loading by name http://www.tutorialspoint.com/java/lang/class_forname_loader.htm

Answer 2

Yes, it's possible. I would recommend you to try jsonschema2pojo. Just paste you JSON and select source type JSON.
