Is is mandatory for the object sent through RestTemplate.postForObject to match exactly the type of object on the server side? I have written server a server side API that accepts a base class of the specific objects being sent through RestTemplate, and I’m receiving a 400 Bad Response from server. If the class of object is the same on both sides, it works fine.

    Yes it is mandatory to match because resttemplate converts your object to specified representation(eg: into XMl or JSON) and at the serverside @requestbody unmarshalls to specifed object so if you are using baseclass, your root element changes making it impossible to unmarshal.

    Hope this helps.
