public class RequestDataBinder<T>
extends org.springframework.validation.DataBinder

A DataBinder that uses a Request to bind its values to the target object.
This class is especially useful inside a Webservice, as shown below:

byte[] processRequest(Site site, Application application, Environment environment, Request request)
        throws BusinessException;
    RequestDataBinder requestDataBinder = new RequestDataBinder(new Person(), request);
    Person person = requestDataBinder.bind();
    // proceed with person
}
 

Also note the possibility to set a custom ConversionService for the binder.
