I'm kinda new to Spring and I'd like to know how to addOject in RedirectView just like in ModelAndView where I can add objects that can be used in views.
mnv = new ModelAndView( FORM_URL );
mnv.addObject( "wpassbook", passbook );
return mnv;
RedirectView redirectView = new RedirectView( "/credit" + FORM_URL );
return new ModelAndView( redirectView );
Anyway, here is the whole method:
/**
* Accepts POST request for this resource url.
*
* @param formBean bean containing values entered by the user
* @param bindingResult contains validation failure messages if form bean is invalid
* @param request instance of HttpServletRequest created by the container
* @return the presentation layer & model object with errors to be rendered if validation fails, if successful a
* redirect is done.
*/
@RequestMapping( value = { FORM_URL }, method = RequestMethod.POST )
public ModelAndView processData( @ModelAttribute( "bean" ) @Valid final HostFinancialRequest formBean,
final BindingResult bindingResult, HttpServletRequest request, @RequestParam("passbook") String passbook )
{
ModelAndView mnv = null;
if ( request.getSession() == null )
{
mnv = new ModelAndView( "timeout.jsp" );
// display session timeout page
// add session timeout message error
mnv.addObject( DepositsControllerUtil.VAR_ERROR_MESSAGE,
ErrorCode.BDS_USER_SESSION_TIMEOUT.getDescription() );
return mnv;
}
// check if validation failed
if ( bindingResult.hasErrors() )
{
mnv = new ModelAndView( FORMVIEW );
// check if teller override boolean flag is to be enabled
DepositsControllerUtil.checkTellerOverrideError( mnv, bindingResult );
// add static values
loadDefault( mnv.getModelMap() );
// return to presentation layer with model that contains errors
return mnv;
}
/* ======== Validation if successful, continue processing then do a redirect======= */
// add required fields
fieldGenerator.populateConstantHeader( formBean, request );
// save transaction
Journal journal = journalManagerImpl.saveJournal( formBean );
// convert the id to be code before sending to host
Currency currency = currencyManagerImpl.get( journal.getCurrency().getCurrCode() );
formBean.setCurrency( Integer.valueOf( currency.getCurrCode() ) );
// send to host
Map<String, Object> returnMap = hostConnectionDelegate.invoke( formBean, wsBean );
// get response from the returned map
HostRequest response = HostConnectionDelegateUtil.getHostResponse( returnMap );
accountPostingValidator.validate( response, bindingResult );
// check if validation failed
if ( bindingResult.hasErrors() )
{
mnv = new ModelAndView( FORMVIEW );
// check if teller override boolean flag is to be enabled
DepositsControllerUtil.checkTellerOverrideError( mnv, bindingResult );
// add static values
loadDefault( mnv.getModelMap() );
mnv.addObject( "postingRestrictionCode", response.getPostingRestrictionCode() );
// return to presentation layer with model that contains errors
return mnv;
}
else
{
// update transaction table based on host response
if ( !HostConnectionDelegateUtil.isApproved( response ) )
{
journal.setErrorCode( response.getErrorCode() );
journal.setStatus( response.getStatus() );
}
else
{
journal.setStatus( response.getStatus() );
}
// save journal
journalManagerImpl.saveJournal( journal );
if ( request.getSession() != null )
{
// add response to session for the presentation layer to display
// transaction results.
request.getSession().setAttribute( "bean", response );
}
RedirectView redirectView = new RedirectView( "/credit" + FORM_URL );
return new ModelAndView( redirectView );
}
}
I'd like to implement the codes above in the method below.
TIA.
To carry data across a redirect use RedirectAttributes.addFlashAttribute(key, value)
.
From the doc:
A RedirectAttributes model is empty when the method is called and is never used unless the method returns a redirect view name or a RedirectView.
After the redirect, flash attributes are automatically added to the model of the controller that serves the target URL.
public ModelAndView processData(
@Valid final HostFinancialRequest formBean,
final BindingResult bindingResult,
HttpServletRequest request,
@RequestParam String passbook,
RedirectAttributes redirectAttributes) {
// do work an then setup the redirect attributes
redirectAttributes.addFlashAttribute("key", value);
return new ModelAndView("redirect:/credit" + FORM_URL);
}
