WebAppInitializer：

 

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
         AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
            appContext.register(WebMvcConfig.class);
              
            ServletRegistration.Dynamic dispatcher = servletContext.addServlet(
                    "SpringDispatcher", new DispatcherServlet(appContext));
            dispatcher.setLoadOnStartup(1);
            dispatcher.addMapping("/");
    }
}

类 CustomerController：

@Controller
public class CustomerController {
    @RequestMapping("/")
    public ModelAndView home() {
        ModelAndView mav = new ModelAndView("index");
        mav.addObject("message", "Heloo Hoapm");
        return mav;
    }
}

类配置：

@ComponentScan("springmvc")
public class WebMvcConfig {
    @Bean(name = "viewResolver")
    public InternalResourceViewResolver getViewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/views/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

这里的结果是这些错误

请帮帮我。非常感谢
