Question

Я разрабатываю приложение Spring Boot, которое содержит контроллер API Rest и веб-контроллер Mvc.

Однако, когда я пытаюсь открыть веб-страницу localhost: 8080 / discovery-service / v1 / health, котораясвязанный с контроллером Web Mvc, я получаю следующую ошибку:

Не найдено сопоставление для HTTP-запроса с URI [/WEB-INF/JSP/restapis.jsp] в DispatcherNo сопоставление найдено для HTTP-запроса с URI [/ WEB-INF / JSP / restapis.jsp] в DispatcherServlet с именем dispatcherServlet'Servlet с именем dispatcherServlet '

        rootContext.register(DiscoveryServiceBeanConfiguration.class);

        container.addListener(new ContextLoaderListener(rootContext));
        AnnotationConfigWebApplicationContext dispatcherServlet=new AnnotationConfigWebApplicationContext();

        ServletRegistration.Dynamic dispatcher=container.addServlet("dispatcher",new DispatcherServlet(dispatcherServlet));

@Controller
@RequestMapping("/discovery-service/v1")
public class HealthController {

    @Autowired
    private RestAPIRepository restAPIRepository;

    @RequestMapping("/health")
    public String monitorHealth(Model model){
        List<RestAPI> restAPIs=restAPIRepository.findAll();

        model.addAttribute("restAPIs",restAPIs);

        return "restapis";
    }
}

Это src / main / resources / WEB-INF / JSP / restapis.jsp, src / main / WEB-INF / JSP / restapis.jsp и src / main / webapp / WEB-INF/JSP/restapis.jsp в системе.
