Here are the classes that I utilize. However, the issue arises when I receive a JSON-string (which is essentially a ProtocolContainer that has been serialized elsewhere and obtained via a web service) and need to deserialize it. JSON-string: Here is a login request reply packet with a m...

First, we need to create an instance of ‘Jackson2JsonRedisSerializer’ and specify the type of objects we want to serialize and deserialize. In this case, it will be the ‘User’ class. Jackson2JsonRedisSerializer<User>serializer=newJackson2JsonRedisSerializer<>(User.class); ...
The proper way to test things here would then be serializing full value, deserializing -- Jackson only guarantees it should be able to deserialize polymorphic values it writes and not arbitrary JSON. Ordering of properties should not, however, matter. ...
What I mean here is that given a single static (declared) type, one will still be able to deserialize instances of multiple types. The challenge is that when serializing things there is no problem -- type is available from instance being serialized -- but to deserialize properly, additional ...

Jackson has little trouble figuring out pieces necessary, and producing expected value. It may well be the only Java JSON package that does this (and more) at this point. 5. Polymorphic types Here's another factoid: inheritance and polymorphic types can be great tools for OO developers; but...
