ApplicationContextException: невозможно запустить веб-сервер

У меня есть небольшой проект с Spring Boot, GraphQL и MySQL / MariaDB. Я следовал этому уроку https://bezkoder.com/spring-boot-graphql-mysql-jpa/ и мой основной класс выглядит так: 

package com.package;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Но всегда, когда я пытаюсь запустить приложение, я получаю следующую ошибку: 

2020-04-08 13:56:39.396  WARN 17467 --- [  restartedMain] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean.

после небольшого поиска в Google я нашел решение для моей проблемы. Проблема заключалась в зависимости, которая использовалась в руководстве. 


        <dependency>
            <groupId>com.graphql-java</groupId>
            <artifactId>graphql-spring-boot-starter</artifactId>
            <version>5.0.2</version>
        </dependency>

// edit: теперь я могу запустить приложение Spring Boot, но когда мне нужно получить доступ к серверу GraphQL в определенной конечной точке тогда я получил только 404.
