Class AbstractHandlerMethodMapping<T>

java.lang.Object

org.springframework.context.support.ApplicationObjectSupport

org.springframework.web.reactive.handler.AbstractHandlerMapping

org.springframework.web.reactive.result.method.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, 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:

5.0

Method

Description

void

afterPropertiesSet()

Detects handler methods at initialization.

protected HandlerMethod

createHandlerMethod(Object handler, Method method)

Create the HandlerMethod instance.

protected void

detectHandlerMethods(Object handler)

Look for handler methods in a handler.

protected @Nullable CorsConfiguration

getCorsConfiguration(Object handler, ServerWebExchange exchange)

Retrieve the CORS configuration for the given handler.

protected Set<String>

getDirectPaths(T mapping)

Return the request mapping paths that are not patterns.

reactor.core.publisher.Mono<HandlerMethod>

getHandlerInternal(ServerWebExchange exchange)

Look up a handler method for the given request.

Map<T, HandlerMethod>

getHandlerMethods()

Return a (read-only) map with all mappings and HandlerMethod's.

protected abstract Comparator<T>

getMappingComparator(ServerWebExchange exchange)

Return a comparator for sorting matching mappings.

protected abstract @Nullable T

getMappingForMethod(Method method, Class<?> handlerType)

Provide the mapping for a handler method.

protected abstract @Nullable T

getMatchingMapping(T mapping, ServerWebExchange exchange)

Check if a mapping matches the current request and return a (potentially new) mapping with conditions relevant to the current request.

protected void

handleMatch(T mapping, HandlerMethod handlerMethod, ServerWebExchange exchange)

Invoked when a matching mapping is found.

protected @Nullable HandlerMethod

handleNoMatch(Set<T> mappings, ServerWebExchange exchange)

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 @Nullable 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
