    InitBinderBindingContext bindingContext = new InitBinderBindingContext(getWebBindingInitializer(),
            this.methodResolver.getInitBinderMethods(handlerMethod));

    InvocableHandlerMethod invocableMethod = this.methodResolver.getRequestMappingMethod(handlerMethod);

    Function<Throwable, Mono<HandlerResult>> exceptionHandler = ex -> handleException(ex, handlerMethod,
            bindingContext, exchange);/*w  w w  .j  av a 2  s .c om*/

    return this.modelInitializer.initModel(handlerMethod, bindingContext, exchange)
            .then(Mono.defer(() -> invocableMethod.invoke(exchange, bindingContext)))
            .doOnNext(result -> result.setExceptionHandler(exceptionHandler))
            .doOnNext(result -> bindingContext.saveModel()).onErrorResume(exceptionHandler);
