title: Right way to write JSON deserializer in Spring or extend it
body: <p>I am trying to write a custom JSON deserializer in Spring. I want to use default serializer for most part of fields and use a custom deserializer for few properties. Is it possible?
  I am trying this way because, most part of properties are values, so for these I can let Jackson use default deserializer; but few properties are references, so in the custom deserializer I have to query a database for reference name and get reference value from database.</p>
  
  <p>I'll show some code if needed.</p>
