@Retention(value=RUNTIME) @Target(value=TYPE) @Documented @Import(value=DelegatingWebMvcConfiguration.class) public @interface EnableWebMvc
Enables default Spring MVC configuration and registers Spring MVC infrastructure components expected by the
DispatcherServlet
. Use this annotation on an @Configuration
class. In turn that will
import DelegatingWebMvcConfiguration
, which provides default Spring MVC configuration.
@Configuration @EnableWebMvc @ComponentScan( basePackageClasses = { MyConfiguration.class }, excludeFilters = { @Filter(type = FilterType.ANNOTATION, value = Configuration.class) } ) public class MyConfiguration { }
To customize the imported configuration implement WebMvcConfigurer
, or more conveniently extend
WebMvcConfigurerAdapter
overriding specific methods only. Any @Configuration
class that
implements WebMvcConfigurer
will be detected by DelegatingWebMvcConfiguration
and given
an opportunity to customize the default Spring MVC code-based configuration.
@Configuration @EnableWebMvc @ComponentScan( basePackageClasses = { MyConfiguration.class }, excludeFilters = { @Filter(type = FilterType.ANNOTATION, value = Configuration.class) } ) public class MyConfiguration extends WebMvcConfigurerAdapter { @Override public void addFormatters(FormatterRegistry formatterRegistry) { formatterRegistry.addConverter(new MyConverter()); } @Override public void configureMessageConverters(List<HttpMessageConverter<?>> converters) { converters.add(new MyHttpMessageConverter()); } // @Override methods ... }
