错误：没有找到带有 URI spring mvc 且没有 xml 的 HTTP 请求的映射

Question

从控制器返回 Html 页面时出现此错误

org.springframework.web.servlet.PageNotFound noHandlerFound 警告：在名称为“dispatcher”的 DispatcherServlet 中找不到带有 URI [/SpringMVCDemo/WEB-INF/response.html] 的 HTTP 请求的映射

response.html 应该放在哪里？

这是我的代码

Controller class
-----------------
@Controller
public class LoginController {

    @RequestMapping("/login")
    public ModelAndView login(@RequestParam(name = "username") String username,
                             @RequestParam(name = "password") String password){

        String str = "Welcome " + username;
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("response");
        modelAndView.addObject("response",str);

        return modelAndView;
    }
}

Config file
------------
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.skuba.*")
public class MvcConfig extends WebMvcConfigurerAdapter{

    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/");
        viewResolver.setSuffix(".html");

        return viewResolver;
    }
}

This is dispatcher controller
------------------------------
public class FrontController extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[] {MvcConfig.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[0];
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] {"/"};
    }
}

假设视图文件位于正确的目录中（即“/WEB-INF/”）尝试将以下内容添加到MvcConfig 类中。

// Use the DefaultServletHandlerConfigurer @Override public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { configurer.enable(); }
