public class WebMvcConfigurationSupport extends java.lang.Object implements ApplicationContextAware, ServletContextAware
@EnableWebMvc
to an
application @Configuration
class. An alternative more
advanced option is to extend directly from this class and override methods as
necessary, remembering to add @Configuration
to the
subclass and @Bean
to overridden @Bean
methods.
For more details see the javadoc of @EnableWebMvc
.
This class registers the following HandlerMappings
:
RequestMappingHandlerMapping
ordered at 0 for mapping requests to annotated controller methods.
HandlerMapping
ordered at 1 to map URL paths directly to view names.
BeanNameUrlHandlerMapping
ordered at 2 to map URL paths to controller bean names.
HandlerMapping
ordered at Integer.MAX_VALUE-1
to serve static resource requests.
HandlerMapping
ordered at Integer.MAX_VALUE
to forward requests to the default servlet.
Registers these HandlerAdapters
:
RequestMappingHandlerAdapter
for processing requests with annotated controller methods.
HttpRequestHandlerAdapter
for processing requests with HttpRequestHandlers
.
SimpleControllerHandlerAdapter
for processing requests with interface-based Controllers
.
Registers a HandlerExceptionResolverComposite
with this chain of
exception resolvers:
ExceptionHandlerExceptionResolver
for handling exceptions through
ExceptionHandler
methods.
ResponseStatusExceptionResolver
for exceptions annotated with
ResponseStatus
.
DefaultHandlerExceptionResolver
for resolving known Spring
exception types
Registers an AntPathMatcher
and a UrlPathHelper
to be used by:
RequestMappingHandlerMapping
,
HandlerMapping
for ViewControllers
HandlerMapping
for serving resources
PathMatchConfigurer
.
Both the RequestMappingHandlerAdapter
and the
ExceptionHandlerExceptionResolver
are configured with default
instances of the following by default:
ContentNegotiationManager
DefaultFormattingConversionService
OptionalValidatorFactoryBean
if a JSR-303 implementation is available on the classpath
HttpMessageConverters
depending on the third-party
libraries available on the classpath.

Note: This method cannot be made final due to CGLIB constraints.
Rather than overriding it, consider overriding configureHandlerExceptionResolvers(java.util.List<org.springframework.web.servlet.HandlerExceptionResolver>)
which allows for providing a list of resolvers.

Adding resolvers to the list turns off the default resolvers that would otherwise
be registered by default. Also see addDefaultHandlerExceptionResolvers(java.util.List<org.springframework.web.servlet.HandlerExceptionResolver>)
that can be used to add the default exception resolvers.
