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

Class MatrixVariableMapMethodArgumentResolver

java.lang.Object

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

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

All Implemented Interfaces:

HandlerMethodArgumentResolver, SyncHandlerMethodArgumentResolver

public class MatrixVariableMapMethodArgumentResolver
extends HandlerMethodArgumentResolverSupport
implements SyncHandlerMethodArgumentResolver

Resolves arguments of type Map annotated with @MatrixVariable where the annotation does not specify a name. In other words the purpose of this resolver is to provide access to multiple matrix variables, either all or associated with a specific path variable.

When a name is specified, an argument of type Map is considered to be a single attribute with a Map value, and is resolved by MatrixVariableMethodArgumentResolver instead.

Since:

5.0.1
