Examples of org.springframework.web.servlet.FlashMapManager

org.springframework.web.servlet.FlashMapManager
A strategy interface for storing, retrieving, and managing {@code FlashMap}instances. See {@link FlashMap} for a general overview of flash attributes.
A FlashMapManager is invoked at the beginning and at the end of requests. For each request it retrieves an "input" FlashMap with attributes passed from a previous request (if any) and creates an "output" FlashMap with attributes to pass to a subsequent request. "Input" and "output" FlashMap instances are exposed as request attributes and are accessible via methods in {@code org.springframework.web.servlet.support.RequestContextUtils}.
Annotated controllers will usually not use this FlashMap directly. See {@code org.springframework.web.servlet.mvc.support.RedirectAttributes}. @author Rossen Stoyanchev @since 3.1 @see FlashMap
