From source file:de.iew.web.isc.spring.IscRequestMethodArgumentResolver.java

public Object resolveArgument(MethodParameter methodParameter, ModelAndViewContainer modelAndViewContainer,
        NativeWebRequest nativeWebRequest, WebDataBinderFactory webDataBinderFactory) throws Exception {
    DSRequest dsRequest = new DSRequest();
    WebDataBinder binder = webDataBinderFactory.createBinder(nativeWebRequest, dsRequest, "dsRequest");
    binder.setFieldMarkerPrefix("__");

    // Man kann noch eigene Property Editoren konfigurieren
    //binder.registerCustomEditor();

    if (binder instanceof ServletRequestDataBinder) {
        /*//from  w  w w  . j  av  a  2 s.c om
        @TODO
                
        Wir machen es uns etwas leicht. Unser DSRequest Objekt muss
        eigentlich nur die isc_-Eigenschaften kennen. Dort ist auch isc_metaDataPreifx
        konfiguriert. Anhand dieses Prefix mssen wir die anderen Eiegenschaften auflsen.
         */
        ServletRequestDataBinder servletRequestDataBinder = (ServletRequestDataBinder) binder;
        HttpServletRequest request = (HttpServletRequest) nativeWebRequest.getNativeRequest();

        servletRequestDataBinder.bind(request);

        BindingResult bindingResult = binder.getBindingResult();
        modelAndViewContainer.addAttribute(BindingResult.MODEL_KEY_PREFIX + "dsRequest", bindingResult);

        return dsRequest;
    } else {
        throw new UnsupportedOperationException(
                "Using " + binder.getClass() + " WebDataBinder is not supported.");
