Spring annotation MVC return 404

Question

I have built a Spring MVC skeleton Helloworld app that returns 404. here is the code:

Controller:

@Controller
@RequestMapping("/")
public class HelloWorldController {
  @RequestMapping(value = {"/helloworld**"}, method = RequestMethod.GET)
  public ModelAndView welcomePage() {
    ModelAndView model = new ModelAndView();
    model.setViewName("helloworld");
    return model;
  }
}

Config:

@Configuration
public class MvcWebApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

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

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

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

@EnableWebMvc
@Configuration
@ComponentScan(basePackages =  "com.tmlink.springmvc.controller.*")
public class RootConfig extends WebMvcConfigurerAdapter {
  @Bean
  public InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver viewResolver
            = new InternalResourceViewResolver();
    viewResolver.setViewClass(JstlView.class);
    viewResolver.setPrefix("/WEB-INF/views/");
    viewResolver.setSuffix(".jsp");
    return viewResolver;
  }
}

@Configuration
public class ServletConfig extends WebMvcConfigurerAdapter {}

There is no XML config and helloworld.jsp is in WEB-INF/views/helloworld.jsp

When requesting http://localhost:8080/helloworld.jsp I get a 404.

The log from Tomcat at startup:

Tomcat version: 7.0.56, Java version: 1.7.0.67.

Any idea what is wrong here?

Answer 1

Change to

@RequestMapping("/*")

Answer 2

Found the error:

@ComponentScan(basePackages = "com.tmlink.springmvc.controller.*")

should have been:

@ComponentScan(basePackages = "com.tmlink.springmvc.controller")

in RootConfig class.
