运行springboot应用程序时出错

Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.

我尝试了以下链接中提供的解决方案

Spring boot -- Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean

这是我的pom

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.1.RELEASE</version>
    </parent>
    <properties>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>

        <!-- spark launcher -->

        <dependency>
            <groupId>org.apache.spark</groupId>
            <artifactId>spark-launcher_2.10</artifactId>
            <version>2.0.0</version>
        </dependency>

        <!-- Redis Dependencies -->

        <dependency>
            <groupId>org.springframework.boot</groupId>

        </dependency>

        <!-- Web -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- Tomcat Embed -->

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </dependency>

        <!-- JSTL -->

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
        </dependency>

        <!-- To compile JSP files -->
        <dependency>

            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>provided</scope>
        </dependency>

        <!-- Json -->

        <dependency>
            <groupId>org.json</groupId>
            <artifactId>json</artifactId>
            </dependency>

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <scope>provided</scope>
        </dependency>

    </dependencies>

下面是主要的：

@SpringBootApplication
@ComponentScan("com.howtodoinjava.app")
public class SpringBootWebApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootWebApplication.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(SpringBootWebApplication.class, args);
    }
}

下面是控制器

@Controller
public class IndexController {

    private SparkRepo sparkRepo;

    public IndexController(SparkRepo sparkRepo) {
        this.sparkRepo = sparkRepo;
    }

    @RequestMapping(method = RequestMethod.POST, path = "/appLaunch")
    public String getData(Model model) throws IOException, InterruptedException {

        int status = sparkRepo.sparkJobStatus();
        model.addAttribute("status", status);
        return "recommendation";
    }
    // ModelAndView model = new ModelAndView("recommendation");

}

及其以下是实现：

@Repository
public class SparkImpl implements SparkRepo {

    SimpleDateFormat format = new SimpleDateFormat("yy/MM/dd HH:mm:ss");

    @Override
    public int sparkJobStatus() throws IOException, InterruptedException {
        Process spark = new SparkLauncher().setAppResource("/my/app.jar")
                .setMainClass("my.spark.app.Main")
                .setMaster("local")
                .setConf(SparkLauncher.DRIVER_MEMORY, "2g")
                .launch();

        return spark.waitFor();
    }
}

这是我运行后遇到的错误

我是springboot的新手，并且还在不同的方案行中添加了tomcat的作用域，并将其删除。但仍然出现错误：

Geeting错误：由于缺少EmbeddedServletContainerFactory bean而无法启动EmbeddedWebApplicationContext
