unable to return a page from Restcontroller - spring

Question

I am using stripe as a payment gateway. I just need to return a page from Webhook controller which is a rest controller. I know Restcontroller should not return a view but can't see any other option except this. Now I am using ModelandView interface to return a view but unable to do that. So please tell me that how can I return a view from restcontroller and what is wrong in this code.
#RestController
public class StripeWebhookController {
#Autowired
private FoodhubServiceImpl service;
#Autowired
private Payment payment;
private String endpointSecret="some endpointSecret";
#PostMapping("/foodhub/endpoint")
public ModelAndView handleStripeEvents(#RequestBody String payload, #RequestHeader("Stripe-Signature") String sigHeader, HttpServletRequest request) {
if(sigHeader == null) {
System.out.println("sigheader is null");
return null;
}
Event event;
// Only verify the event if you have an endpoint secret defined.
// Otherwise use the basic event deserialized with GSON.
try {
event = Webhook.constructEvent(
payload, sigHeader, endpointSecret
);
} catch (SignatureVerificationException e) {
// Invalid signature
System.out.println("Webhook error while validating signature.");
System.out.println(e);
return null;
}
// Deserialize the nested object inside the event
EventDataObjectDeserializer dataObjectDeserializer = event.getDataObjectDeserializer();
StripeObject stripeObject = null;
if (dataObjectDeserializer.getObject().isPresent()) {
stripeObject = dataObjectDeserializer.getObject().get();
} else {
// Deserialization failed, probably due to an API version mismatch.
// Refer to the Javadoc documentation on `EventDataObjectDeserializer` for
// instructions on how to handle this case, or return an error here.
}
// Handle the event
switch (event.getType()) {
case "payment_intent.succeeded":
PaymentIntent paymentIntent = (PaymentIntent) stripeObject;
System.out.println("Payment succeeded for "+paymentIntent.getAmount());
handlePaymentIntentSucceeded(paymentIntent);
// Then define and call a method to handle the successful payment intent.
break;
default:
System.out.println("Unhandled event type: " + event.getType());
break;
}
ModelAndView mv = new ModelAndView();
mv.setViewName("payment-success.jsp");
return mv;
}
