Is your feature request related to a problem? Please describe.

useAbstractionForFiles exists for file param but doesn't change the returned type.

Describe the solution you'd like

When useAbstractionForFiles is true, like the param type, the return type should be Resource instead of File.

hi juherr can I solve this issue

I think only resttemplate and webclient libraries support this feature at the moment. We welcome contributions to support this feature in other libraries (e.g. jersey2, okhttp-gson, etc)

As a workaround, Resource can be forced by configuration:

                            <typeMappings>
                                <typeMapping>File=org.springframework.core.io.Resource</typeMapping>
                            </typeMappings>
                            <configOptions>
                                <useAbstractionForFiles>true</useAbstractionForFiles>
                            </configOptions>
