三個配置文件

public class DispatcherServletConfig extends AbstractAnnotationConfigDispatcherServletInitializer
{
    @Override
    protected Class<?>[] getRootConfigClasses()
    {
        return new Class<?>[]{BeanConfig.class};
    }

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

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

@Configuration
@EnableWebMvc
@ComponentScan(basePackageClasses = {BasePackageMarker.class})
public class WebConfig extends WebMvcConfigurerAdapter
{
}

@Configuration
public class BeanConfig
{
}

測試

@RestController
public class IndexController
{
    @GetMapping("/test")
    public String test() {
        return "Hello there.";
    }
}
