三个配置文件

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
{
}

测试

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