Не так ли, что с встроенными контейнерами сервлетов, что я пытаюсь сделать, просто позвольте ему показать простую страницу Jsp. Я использую встроенный контейнер tomcat. Я пробовал 2 подхода, и оба не удалось.Spring Boot MVC Can not Show Jsp
Первый подход: applications.properties
# MVC
spring.mvc.view.prefix:/WEB-INF/jsp/
spring.mvc.view.suffix:.jsp
Это дает мне пустую страницу (не в одной строке HTML)
Я также попытался изменения без MVC. это привело к тому, что сервлет не нашел страницу вообще.
Второй подход: Java конфигурации
@Configuration
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter{
@Bean
public ViewResolver getViewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/jsp/");
resolver.setSuffix(".jsp");
return resolver;
}
@Override
public void configureDefaultServletHandling(
DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
Это возвращает плоский текст в браузере (это то, что я вижу на на экране браузера, а не проверять страницы) 
Мой контроллер:
@Controller
public class PageController {
@GetMapping("/index")
public ModelAndView getView(){
return new ModelAndView("index");
}
Основной класс:
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
/**
* @param args the command line arguments
*/
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

Заранее спасибо!
вау, спасибо это решило проблему для подхода 2 –
пожалуйста, примите ответ, если он работает, спасибо. – mhshimul
Это не единственная проблема, есть слишком много плагинов и слишком много зависимостей (и даже конфликтующих). Ему нужна тщательная очистка от его помпы. –
