SessionThemeResolver (Spring Framework 4.3.30.RELEASE API)

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

All Implemented Interfaces:
ThemeResolver
```
public class SessionThemeResolver
extends AbstractThemeResolver
```
ThemeResolver implementation 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.
