I try to create a simple Spring MVC and run in tomcat via eclipse ide with one simple controller:

    @Controller
    public class HomeController {
    
        @RequestMapping("/home")
        public String helloWorld(Model model) {
            model.addAttribute("message", "home university!");
            return "home";
        }
    }

my other configs:

webinitializer:

public class WebAppInitializer implements WebApplicationInitializer{

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.register(MvcConfig.class, ServiceConfig.class,  AspectConfig.class, DaoConfig.class, DataSourceConfig.class);
        context.setServletContext(servletContext);
     
        ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispather", new DispatcherServlet(context));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");
    }
}

MvcSpringJavaConfig:

public class MvcConfig {
   
    @Configuration
    @ComponentScan(basePackages = "img.imaginary.controller")
    @EnableWebMvc
    public class MvcConfiguration {

        @Bean
        public ViewResolver getViewResolver() {
            InternalResourceViewResolver resolver = new InternalResourceViewResolver();
            resolver.setPrefix("/WEB-INF/views/");
            resolver.setSuffix(".jsp");
            return resolver;
        }
    }
}

structure:

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                                http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
            id="WebApp_ID" version="3.1">
   
</web-app>

my pom.xml: pom.xml

and when tomcat starts and I try to open the app in the browser, I get a 404 status and a description:

The source server has not found the current representation of the target resource or does not want to disclose its existence.

I tried to change the controller and the web.xml and other configs, but I always get this result

I can't figure out what I'm missing in order for my simple home controller to start correctly

CodePudding user response：

you should add @Configuration to MvcConfig class. also by referring to this:

Any nested configuration classes must be declared as static.

MvcConfiguration class must be static.
