Class CookieThemeResolver

java.lang.Object

org.springframework.web.util.CookieGenerator

org.springframework.web.servlet.theme.CookieThemeResolver

All Implemented Interfaces:

ThemeResolver

public class CookieThemeResolver
extends CookieGenerator
implements ThemeResolver

ThemeResolver implementation that uses a cookie sent back to the user in case of a custom setting, with a fallback to the default theme. This is particularly useful for stateless applications without user sessions.

Custom controllers can thus override the user's theme by calling setThemeName, e.g. responding to a certain theme change request.
