public class MatrixVariableMapMethodArgumentResolver extends java.lang.Object implements HandlerMethodArgumentResolver
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.
