运行Spring Boot应用程序时出错

由于缺少EmbeddedServletContainerFactory bean，无法启动EmbeddedWebApplicationContext。

我尝试了以下链接中提供的解决方案：

Spring boot -- 由于缺少EmbeddedServletContainerFactory bean，无法启动EmbeddedWebApplicationContext

这是我的pom文件

以下是主要部分：

@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);
}
}

以下是控制器：

@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");
}

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();
}
}

运行后出现以下错误：

我是Spring Boot的新手，尝试了不同的场景，例如添加tomcat的范围，删除它。

但仍然出现错误。
