我有一个现有的Spring Web应用程序，该应用程序使用两个扩展AbstractController的控制器。我想将Spring
Boot集成到应用程序中，以便我们可以将其作为独立的应用程序运行。

我遇到了一个问题，因为Spring没有将调用转发给我的控制器。如何将控制器映射到URL模式（例如“ / app / *”）？

SampleController.java

@Controller("myController")
public class SampleController extends AbstractController {
    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception {
        response.getWriter().print("Hello world!");
        return null;
    }
}

应用程序

@EnableAutoConfiguration
@Configuration
@ComponentScan
public class Application {
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public SimpleUrlHandlerMapping sampleServletMapping() {
        SimpleUrlHandlerMapping mapping = new SimpleUrlHandlerMapping();

        Properties urlProperties = new Properties();
        urlProperties.put("/index", "myController");

        mapping.setMappings(urlProperties);

        return mapping;
    }
}

启动应用程序时，我收到以下消息：

INFO  [org.springframework.web.servlet.handler.SimpleUrlHandlerMapping] Mapped URL path [/index] onto handler 'myController'

但是，当我向/ index发送请求时，收到以下消息：

DEBUG [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping] Looking up handler method for path /index
DEBUG [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping] Did not find handler method for [/index]
