How to use thymeleaf and jsp in same SpringBoot project?

Question

I know that this question duplicates these questions.

how to use both thymeleaf and jsp in same spring boot project

But none of these sources helped me.

Following one of the previous guides, I added a configuration class. After that, the controller began to see the files, but about calling a file with the extension from the browser .jsp error appears.

here is the project code:

ViewConfiguration.java

@EnableWebMvc
public class ViewConfiguration implements WebMvcConfigurer {
 @Autowired
 WebApplicationContext webApplicationContext;

 @Bean
 public SpringResourceTemplateResolver thymeleafTemplateResolver(){
     SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
     templateResolver.setApplicationContext(webApplicationContext);
     templateResolver.setOrder(9);
     templateResolver.setPrefix("/WEB-INF/views/");
     templateResolver.setSuffix("");
     return templateResolver;
 }

 @Bean
 public SpringTemplateEngine templateEngine() {
     SpringTemplateEngine springTemplateEngine= new SpringTemplateEngine();
     springTemplateEngine.setTemplateResolver(thymeleafTemplateResolver());
     springTemplateEngine.setEnableSpringELCompiler(true);
     return springTemplateEngine;
 }

 @Bean
 public ThymeleafViewResolver thymeleafViewResolver(){
     final ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
     viewResolver.setViewNames(new String[] {"*.html"});
     viewResolver.setExcludedViewNames(new String[] {"*.jsp"});
     viewResolver.setTemplateEngine(templateEngine());
     viewResolver.setCharacterEncoding("UTF-8");
     return viewResolver;
 }

 @Bean
 public InternalResourceViewResolver jspViewResolver(){
     final InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
     viewResolver.setOrder(10);
     viewResolver.setViewClass(JstlView.class);
     viewResolver.setPrefix("/WEB-INF/views/");
     viewResolver.setSuffix("");
     viewResolver.setViewNames("*.jsp");
     return viewResolver;
 }
}

MyController.java

@Controller
public class MyController {
 

    @GetMapping("/1")
    public String jsp() {
        return "jj.jsp";
    }

    @GetMapping("/2")
    public String html() {
        return "hh.html";
    }
}

JspAndThymeleafApplication.java

@SpringBootApplication
public class JspAndThymeleafApplication {

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

}

ServletInitializer.java

public class ServletInitializer extends SpringBootServletInitializer {

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

}
