Spring Boot 2.2.5.RELEASE не может пересылать на JSP в tomcat 8.5.3

Я создаю простое приложение Spring Boot с JSP, используя SB 2.2.5.RELEASE. Вот файловая структура 

.//src/main/java/com/myapp/controllers/HelloController.java
.//src/main/java/com/myapp/MyApplication.java

.//src/main/resources/META-INF/resources/WEB-INF/jsp/hello.jsp

и другое расположение jsp, чтобы увидеть, какой из них работает 

.//src/main/webapp/WEB-INF/jsp/hello.jsp

Главное приложение 

@SpringBootApplication
@EnableConfigurationProperties
public class MyApplication extends SpringBootServletInitializer {

  @Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(MyApplication.class);
  }
  public static void main(String[] args) {
    SpringApplication.run(MyApplication.class, args);
 }
}

Контроллер 

@Controller
@RequestMapping(value = "/hello")
public class HelloController {

  private static final Logger LOGGER = LoggerFactory.getLogger(HelloController.class);

  @GetMapping(value ={"", "/{name}"})
  public String hello(Model model, @PathVariable Optional<String> name) {
    // Should call a greeting service that takes 'name' and returns a Model rendered by the view
    model.addAttribute("name", name.orElse("world"));
    return "hello";
  }
}

My pom 

......
<modelVersion>4.0.0</modelVersion>
<groupId>com.myapp</groupId>
<artifactId>myapp</artifactId>
<version>0.0.14-SNAPSHOT</version>
<packaging>war</packaging>

......
<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>jstl</artifactId>
  <version>1.2</version>
  <scope>compile</scope>
</dependency>

my application.yml 

spring:
  profiles: local
  mvc.view:
    prefix: /WEB-INF/jsp/
    suffix: .jsp

в моем локальном запуске Spring Boot, инициированном плагином IDE или SB maven, JSP являются разрешается плавно

, но после того, как я разверну войну в Tomcat 8.5.3, неясно, как разрешить JSP, хотя я дал JSP в любом месте или в обоих

Но он нашел префикс / суффикс просмотра mvc, как указано в журнале 

2020-05-06 15:26:22.034 DEBUG 11973 --- [ost-startStop-1] o.s.c.e.PropertySourcesPropertyResolver  : Found key 'spring.mvc.view.prefix' in PropertySource 'configurationProperties' with value of type String

Я искал повсюду, например

Spring Boot JSP 404

попробовал все, что они предлагали, у меня ничего не работает :(. Могу я получить помощь / подсказки / подсказки, пожалуйста? Это так расстраивает
