Package org.springframework.web.servlet.config.annotation

Class WebMvcConfigurationSupport

java.lang.Object

org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport

All Implemented Interfaces:

Aware, ApplicationContextAware, ServletContextAware

Direct Known Subclasses:

DelegatingWebMvcConfiguration

public class WebMvcConfigurationSupport
extends Object
implements ApplicationContextAware, ServletContextAware

This is the main class providing the configuration behind the MVC Java config. It is typically imported by adding @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.
• RouterFunctionMapping ordered at 3 to map router functions.
• 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.
• HandlerFunctionAdapter for processing requests with router functions.

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:

• the RequestMappingHandlerMapping,
• the HandlerMapping for ViewControllers
• and the HandlerMapping for serving resources

Note that those beans can be configured with a PathMatchConfigurer.

Both the RequestMappingHandlerAdapter and the ExceptionHandlerExceptionResolver are configured with default instances of the following by default:

• a ContentNegotiationManager
• a DefaultFormattingConversionService
• an OptionalValidatorFactoryBean if a JSR-303 implementation is available on the classpath
• a range of HttpMessageConverters depending on the third-party libraries available on the classpath.

Since:

3.1

Add custom HandlerMethodArgumentResolvers to use in addition to the ones registered by default.

Custom argument resolvers are invoked before built-in resolvers except for those that rely on the presence of annotations (e.g. @RequestParameter, @PathVariable, etc). The latter can be customized by configuring the RequestMappingHandlerAdapter directly.

Add custom HandlerMethodReturnValueHandlers in addition to the ones registered by default.

Custom return value handlers are invoked before built-in ones except for those that rely on the presence of annotations (e.g. @ResponseBody, @ModelAttribute, etc). The latter can be customized by configuring the RequestMappingHandlerAdapter directly.

Parameters:

returnValueHandlers - the list of custom handlers (initially an empty list)

getMessageConverters

protected final List<HttpMessageConverter<?>> getMessageConverters()

configureMessageConverters

protected void configureMessageConverters(List<HttpMessageConverter<?>> converters)

Override this method to add custom HttpMessageConverters to use with the RequestMappingHandlerAdapter and the ExceptionHandlerExceptionResolver.

Adding converters to the list turns off the default converters that would otherwise be registered by default. Also see addDefaultHttpMessageConverters(java.util.List<org.springframework.http.converter.HttpMessageConverter<?>>) for adding default message converters.

Parameters:

converters - a list to add message converters to (initially an empty list)

extendMessageConverters

protected void extendMessageConverters(List<HttpMessageConverter<?>> converters)

Override this method to extend or modify the list of converters after it has been configured. This may be useful for example to allow default converters to be registered and then insert a custom converter through this method.

Since:

4.1.3

addDefaultHttpMessageConverters

protected final void addDefaultHttpMessageConverters(List<HttpMessageConverter<?>> messageConverters)
