Hey guys ,how u are implementing Exception handling in Vertx . I am more concerned to do Centralized Exception Handling in Vertx project
Right now for every route we can have handler ,but not for every custom exception .
So I want to map Custom Exception to Specific handler ,Is there better way to do it you can suggest

So if i throw in any route handler
get("/order") .coroutineHandler { orderHandlers.getOrders(it) }

//Handler of above route
suspend fun getOrders(ctx: RoutingContext) {
throw InvalidJsonException("InValid Json Data ")

ctx.response().end(json {
obj("id" to 12, "getRating" to 324).encode()
})

}

This is caught by Failure handler of that route but for every Custom exception i have to do If else and the handle it .
I think there should be better way to map Custom Exceptions to their handlers and send response back .

Jooby Framework provide mapping of its own like this :-

err(GenericSystemException::class.java, ::handleGenericSytemError)
err(InvalidJSONInputException::class.java, ::handleInvalidJSONError)
err(InputValidationException::class.java, ::handleInputValidationError)



Need suggestion How it should be implemented in Vertx Project
