Theme support classes for Spring's web MVC framework.

and a HandlerInterceptor for theme changes.



    

  • If you don't provide a bean of one of these classes as themeResolver, a FixedThemeResolver will be provided with the default theme name 'theme'.
    • 

  • If you use a defined FixedThemeResolver, you will able to use another theme name for default, but the users will stick on this theme.

  • Generally, you will put in the themes resource bundles the paths of CSS files, images and HTML constructs.
    •
