extends AbstractNamedValueSyncArgumentResolver
Class Inheritance
Imports
java.util.ArrayList, .List, .Map, org.springframework.beans.factory.config.ConfigurableBeanFactory, org.springframework.core.MethodParameter, .ReactiveAdapterRegistry, org.springframework.lang.Nullable, org.springframework.util.Assert, .CollectionUtils, .MultiValueMap, .StringUtils, org.springframework.web.bind.annotation.MatrixVariable, .ValueConstants, org.springframework.web.reactive.HandlerMapping, org.springframework.web.server.MissingRequestValueException, .ServerErrorException, .ServerWebExchange, .ServerWebInputException
Resolves arguments annotated with @MatrixVariable.

If the method parameter is of type Map it will be resolved by MatrixVariableMapMethodArgumentResolver instead unless the annotation specifies a name in which case it is considered to be a single attribute of type map (vs multiple attributes collected in a map).

Method Summary

Modifier and TypeMethod and Description
protected AbstractNamedValueArgumentResolver.NamedValueInfo
createNamedValueInfo(MethodParameter
the method parameter
parameter)

Implements abstract org.springframework.web.reactive.result.method.annotation.AbstractNamedValueArgumentResolver.createNamedValueInfo.

Create the NamedValueInfo object for the given method parameter.

protected void
handleMissingValue(String
the name for the value
name, MethodParameter
the method parameter
parameter)

Overrides org.springframework.web.reactive.result.method.annotation.AbstractNamedValueArgumentResolver.handleMissingValue.

Invoked when a named value is required, but resolveName(String, MethodParameter, ServerWebExchange) returned null and there is no default value.

protected Object
resolveNamedValue(String name, MethodParameter param, ServerWebExchange exchange)

Implements abstract org.springframework.web.reactive.result.method.annotation.AbstractNamedValueSyncArgumentResolver.resolveNamedValue.

Actually resolve the value synchronously.

public boolean
supportsParameter(MethodParameter
the method parameter
parameter)

Implements org.springframework.web.reactive.result.method.HandlerMethodArgumentResolver.supportsParameter.

Whether this resolver supports the given method parameter.
