There is no way to map JSON you show automatically; it is not one of 4 types supported by Jackson.

If you can't make server produce more standard structure (for which automatic support exists), you will need to write a custom deserializer; or to do data-binding in two steps, first into an intermediate easily mappable structure (like JsonNode or Map) and then from that into desired structure manually extracting type, using that (for example, with ObjectMapper.convertValue(object, resultType).
