org.springframework.web.servlet.handler.AbstractHandlerMapping

org.springframework.web.servlet.handler.AbstractHandlerMethodMapping<T>

Type Parameters:

T - the mapping for a HandlerMethod containing the conditions needed to match the handler method to an incoming request.

All Implemented Interfaces:

Aware, BeanNameAware, InitializingBean, ApplicationContextAware, Ordered, ServletContextAware, HandlerMapping

Direct Known Subclasses:

RequestMappingInfoHandlerMapping

public abstract class AbstractHandlerMethodMapping<T>
extends AbstractHandlerMapping
implements InitializingBean

Abstract base class for HandlerMapping implementations that define a mapping between a request and a HandlerMethod.

For each registered handler method, a unique mapping is maintained with subclasses defining the details of the mapping type <T>.

Since:

3.1

protected CorsConfiguration	getCorsConfiguration(Object handler, HttpServletRequest request)	Retrieve the CORS configuration for the given handler.
protected Set<String>	getDirectPaths(T mapping)	Return the request mapping paths that are not patterns.
protected HandlerMethod	getHandlerInternal(HttpServletRequest request)	Look up a handler method for the given request.
Map<T,HandlerMethod>	getHandlerMethods()	Return a (read-only) map with all mappings and HandlerMethod's.
List<HandlerMethod>	getHandlerMethodsForMappingName(String mappingName)	Return the handler methods for the given mapping name.
protected abstract Comparator<T>	getMappingComparator(HttpServletRequest request)	Return a comparator for sorting matching mappings.
protected abstract T	getMappingForMethod(Method method, Class<?> handlerType)	Provide the mapping for a handler method.
protected Set<String>	getMappingPathPatterns(T mapping)	Deprecated. as of 5.3 in favor of providing non-pattern mappings via getDirectPaths(Object) instead
protected abstract T	getMatchingMapping(T mapping, HttpServletRequest request)	Check if a mapping matches the current request and return a (potentially new) mapping with conditions relevant to the current request.
HandlerMethodMappingNamingStrategy<T>	getNamingStrategy()	Return the configured naming strategy or null.
protected void	handleMatch(T mapping, String lookupPath, HttpServletRequest request)	Invoked when a matching mapping is found.
protected HandlerMethod	handleNoMatch(Set<T> mappings, String lookupPath, HttpServletRequest request)	Invoked when no matching mapping is not found.
protected void	handlerMethodsInitialized(Map<T,HandlerMethod> handlerMethods)	Invoked after all handler methods have been detected.
protected boolean	hasCorsConfigurationSource(Object handler)	Return true if there is a CorsConfigurationSource for this handler.
protected CorsConfiguration	initCorsConfiguration(Object handler, Method method, T mapping)	Extract and return the CORS configuration for the mapping.
protected void	initHandlerMethods()	Scan beans in the ApplicationContext, detect and register handler methods.
protected abstract boolean	isHandler(Class<?> beanType)	Whether the given type is a handler with handler methods.
protected HandlerMethod	lookupHandlerMethod(String lookupPath, HttpServletRequest request)	Look up the best-matching handler method for the current request.
protected void	processCandidateBean(String beanName)	Determine the type of the specified candidate bean and call detectHandlerMethods(java.lang.Object) if identified as a handler type.
protected void	registerHandlerMethod(Object handler, Method method, T mapping)	Register a handler method and its unique mapping.
void	registerMapping(T mapping, Object handler, Method method)	Register the given mapping.
void	setDetectHandlerMethodsInAncestorContexts(boolean detectHandlerMethodsInAncestorContexts)	Whether to detect handler methods in beans in ancestor ApplicationContexts.
void	setHandlerMethodMappingNamingStrategy(HandlerMethodMappingNamingStrategy<T> namingStrategy)	Configure the naming strategy to use for assigning a default name to every mapped handler method.
void	setPatternParser(PathPatternParser patternParser)	Set the PathPatternParser to parse patterns with for URL path matching.
void	unregisterMapping(T mapping)	Un-register the given mapping.
