org.springframework.web.servlet.theme
Class SessionThemeResolver

java.lang.Object
  org.springframework.web.servlet.theme.AbstractThemeResolver
      org.springframework.web.servlet.theme.SessionThemeResolver

All Implemented Interfaces:: ThemeResolver

public class SessionThemeResolver
extends AbstractThemeResolver
extends AbstractThemeResolver

Implementation of ThemeResolver that uses a theme attribute in the user's session in case of a custom setting, with a fallback to the default theme. This is most appropriate if the application needs user sessions anyway.

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