You can use the PropertyEditor to convert Strings to more Strings (see the
String Trimmer example in the Spring source).
You can extend the AuthenticationViaForm class, similar to this example
below (but you'll be calling the method to register the property editors on
the DataBinder):
package edu.rutgers.enterprise.cas.web.flow;
import org.jasig.cas.web.flow.AuthenticationViaFormAction;
import org.springframework.validation.DataBinder;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.webflow.execution.RequestContext;
public class RestrictedAuthenticationViaFormAction extends
AuthenticationViaFormAction {
protected void initBinder(RequestContext arg0, DataBinder binder) {
final WebDataBinder webBinder = (WebDataBinder) binder;
binder.setAllowedFields(new String[] {"username", "password",
"authenticationType"});
webBinder.setFieldMarkerPrefix(null);
}
}
JavaDoc:
http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/validation/DataBinder.html#registerCustomEditor(java.lang.Class,%20java.lang.String,%20java.beans.PropertyEditor)
There is also another way to do it via the Spring configuration but I'm not
too familiar with that.
