将Jackson序列化对象反序列化为Map <String, Object> ？

Question

I have a string created via objectWriter.writeValueAsString() from an object annotated with Jackson's @JsonType and with fields annotated with @Json that themselves may be @JsonType objects. After the serialization, I'd like to deserialize it to various environments where some of the values may need to be filtered/adjusted. To do this, I'd like to deserialize the base object into a recursive Map with each member field being a Map if they are a @JsonType, or their native type if not. I can then apply some filters to that resultant map, delete branches, fix values etc, before serializing/deserializing it back to it's final format.

I've looked into the Polymorphic Deserialization, but doesn't seem to be what I need.

Is there an easy way to do this without actually creating the @JsonType'ed objects?

Thanks!

It would help if you posted example code. But you can just write a custom deserializer :
