How to Receive Webhook from Stripe in Java

Question

I am trying to receive a webhook via a post request from Stripe Payments. The java method to process it looks like this:

@ResponseBody
@RequestMapping(    consu         


        

Answer 1

In order to abstract all of the deserialization logic out of the controller I did the following:

Created a custom deserializer

public class StripeEventDeserializer extends JsonDeserializer {

    private ObjectMapper mapper;
    
    public StripeEventDeserializer(ObjectMapper mapper) {
        this.mapper = mapper;
    }

    @Override
    public Event deserialize(JsonParser jp, DeserializationContext context) throws IOException {
        ObjectNode root = mapper.readTree(jp);

        Event event = ApiResource.GSON.fromJson(root.toString(), Event.class);
        return event;
    }
}

I then needed to add that deserializer to my ObjectMapper config:

SimpleModule simpleModule = new SimpleModule();
simpleModule.addDeserializer(Event.class, new StripeEventDeserializer(mapper));
mapper.registerModule(simpleModule);

I could then use @RequestBody correctly on the Spring rest controller:

@PostMapping("/webhook")
public void webhook(@RequestBody Event stripeEvent)
