I think it could (this has been raised before by others). If we develop
a bean-based approach to forms (we have all the pieces to do that), then
the parameter approach is essentially an unwrapping of the latter (and
there are ways to plug in different HTTP method processing rules in
Jersey). Time is the main factor... :-)
IMHO I think there needs to be a clearer way to distinguish POST methods
that process forms from POST methods that process other types of
entities. For example,
@FormPOST
public String tester(String x, @Format("application/xml") Profile p) {
}
It also may be possible to unify form-based processing using the URL
encoded mechanism or multipart MIME.
