Class MatrixVariableMethodArgumentResolver

java.lang.Object

org.springframework.web.reactive.result.method.HandlerMethodArgumentResolverSupport

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

org.springframework.web.reactive.result.method.annotation.AbstractNamedValueSyncArgumentResolver

org.springframework.web.reactive.result.method.annotation.MatrixVariableMethodArgumentResolver

All Implemented Interfaces:

HandlerMethodArgumentResolver, SyncHandlerMethodArgumentResolver

public class MatrixVariableMethodArgumentResolver
extends AbstractNamedValueSyncArgumentResolver

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).

Since:

5.0.1

Method Details

supportsParameter

public boolean supportsParameter(MethodParameter parameter)

Description copied from interface: HandlerMethodArgumentResolver

Whether this resolver supports the given method parameter.

Parameters:

parameter - the method parameter

createNamedValueInfo

protected AbstractNamedValueArgumentResolver.NamedValueInfo createNamedValueInfo(MethodParameter parameter)

Description copied from class: AbstractNamedValueArgumentResolver

Create the AbstractNamedValueArgumentResolver.NamedValueInfo object for the given method parameter. Implementations typically retrieve the method annotation by means of MethodParameter.getParameterAnnotation(Class).

Specified by:

createNamedValueInfo in class AbstractNamedValueArgumentResolver

Parameters:

parameter - the method parameter

Returns:

the named value information

resolveNamedValue

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

Description copied from class: AbstractNamedValueSyncArgumentResolver

Actually resolve the value synchronously.

Specified by:

resolveNamedValue in class AbstractNamedValueSyncArgumentResolver

handleMissingValue

protected void handleMissingValue(String name,
 MethodParameter parameter)
                           throws ServerWebInputException

Description copied from class: AbstractNamedValueArgumentResolver

Invoked when a named value is required, but AbstractNamedValueArgumentResolver.resolveName(String, MethodParameter, ServerWebExchange) returned null and there is no default value. Subclasses typically throw an exception in this case.

Overrides:

handleMissingValue in class AbstractNamedValueArgumentResolver

Parameters:

name - the name for the value

parameter - the method parameter

Throws:

ServerWebInputException
