Examples of org.springframework.web.method.support.InvocableHandlerMethod

org.springframework.web.method.support.InvocableHandlerMethod
Provides a method for invoking the handler method for a given request after resolving its method argument values through registered {@link HandlerMethodArgumentResolver}s.
Argument resolution often requires a {@link WebDataBinder} for data binding or for type conversion.Use the {@link #setDataBinderFactory(WebDataBinderFactory)} property to supply a binder factory to pass toargument resolvers.
Use {@link #setHandlerMethodArgumentResolvers(HandlerMethodArgumentResolverComposite)} to customizethe list of argument resolvers. @author Rossen Stoyanchev @since 3.1
