[keycloak-user] Read and Write Theme to a DB

[Yegui Cai]

Hi Dmitry.

Thanks a lot for your hints. By "wring a theme", I mean storing the theme
in DB.

Another approach which may be helpful for my purpose is maybe changing the
theme based on the info stored in DB. It looks like I need to
implement ThemeResourceProvider and its factory. Am i correct?

Best,
Yegui
