Functions

getAdapterRegistry

open fun getAdapterRegistry(): ReactiveAdapterRegistry

Return the configured ReactiveAdapterRegistry.

Inherited Functions

resolveArgument	`abstract fun resolveArgument(parameter: MethodParameter, bindingContext: BindingContext, exchange: ServerWebExchange): Mono<Any>` Resolve the value for the method parameter.
supportsParameter	`abstract fun supportsParameter(parameter: MethodParameter): Boolean` Whether this resolver supports the given method parameter.

Inheritors

ErrorsMethodArgumentResolver	`open class ErrorsMethodArgumentResolver : HandlerMethodArgumentResolverSupport` Resolve Errors or BindingResult method arguments. An `Errors` argument is expected to appear immediately after the model attribute in the method signature.
MatrixVariableMapMethodArgumentResolver	`open class MatrixVariableMapMethodArgumentResolver : HandlerMethodArgumentResolverSupport, SyncHandlerMethodArgumentResolver` Resolves arguments of type Map annotated with where
ModelArgumentResolver	`open class ModelArgumentResolver : HandlerMethodArgumentResolverSupport, SyncHandlerMethodArgumentResolver` Resolver for a controller method argument of type Model that can also be resolved as a java.util.Map.
ModelAttributeMethodArgumentResolver	`open class ModelAttributeMethodArgumentResolver : HandlerMethodArgumentResolverSupport` Resolve `@ModelAttribute` annotated method arguments. Model attributes are sourced from the model, or created using a default constructor and then added to the model. Once created the attribute is populated via data binding to the request (form data, query params). Validation also may be applied if the argument is annotated with `@javax.validation.Valid` or Spring's own `@org.springframework.validation.annotation.Validated`. When this handler is created with `useDefaultResolution=true` any non-simple type argument and return value is regarded as a model attribute with or without the presence of an `@ModelAttribute`.
PathVariableMapMethodArgumentResolver	`open class PathVariableMapMethodArgumentResolver : HandlerMethodArgumentResolverSupport, SyncHandlerMethodArgumentResolver` Resolver for Map method arguments also annotated with PathVariable where the annotation does not specify a path variable name. The resulting Map argument is a coyp of all URI template name-value pairs.
PrincipalArgumentResolver	`open class PrincipalArgumentResolver : HandlerMethodArgumentResolverSupport` Resolves method argument value of type java.security.Principal.
RequestHeaderMapMethodArgumentResolver	`open class RequestHeaderMapMethodArgumentResolver : HandlerMethodArgumentResolverSupport, SyncHandlerMethodArgumentResolver` Resolves Map method arguments annotated with `@RequestHeader`. For individual header values annotated with `@RequestHeader` see RequestHeaderMethodArgumentResolver instead. The created Map contains all request header name/value pairs. The method parameter type may be a MultiValueMap to receive all values for a header, not only the first one.
RequestParamMapMethodArgumentResolver	`open class RequestParamMapMethodArgumentResolver : HandlerMethodArgumentResolverSupport, SyncHandlerMethodArgumentResolver` Resolver for Map method arguments annotated with RequestParam where the annotation does not specify a request parameter name. See RequestParamMethodArgumentResolver for resolving Map method arguments with a request parameter name. The created Map contains all request parameter name-value pairs. If the method parameter type is MultiValueMap instead, the created map contains all request parameters and all there values for cases where request parameters have multiple values.
ServerWebExchangeArgumentResolver	`open class ServerWebExchangeArgumentResolver : HandlerMethodArgumentResolverSupport, SyncHandlerMethodArgumentResolver` Resolves ServerWebExchange-related method argument values of the following types: ServerWebExchange ServerHttpRequest ServerHttpResponse HttpMethod Locale TimeZone ZoneId UriBuilder or UriComponentsBuilder -- for building URL's relative to the current request For the `WebSession` see WebSessionArgumentResolver and for the `Principal` see PrincipalArgumentResolver.
WebSessionArgumentResolver	`open class WebSessionArgumentResolver : HandlerMethodArgumentResolverSupport` Resolves method argument value of type WebSession.
