Hi,
Wicket tries to create a proxy for your bean.
Apparently UserScopeFinder doesn't have a default constructor, which is
required for creation of a proxy class.
Easiest solution is to introduce an interface (e.g. IUserScopeFinder)
and let your bean implement that:
@SpringBean(name = "userScopeFinder")
private IUserScopeFinder userScopeFinder;
Hope this helps

Hi,
i would like to extend a session (metadata) with scope of user logged in. Something like
"allowed countries", "allowed companies" and so on.
That scope is provided by a spring bean (UserScopeFinder). This bean is created
in a Configuration as a @Bean.
What i tried so far is add an ISessionListener to WebApplication and inject the
UserScopeFinder.
@com.giffing.wicket.spring.boot.context.extensions.ApplicationInitExtension
public class AuthorizationInitializer implements
com.giffing.wicket.spring.boot.context.extensions.WicketApplicationInitConfiguration
{
@Override
public void init(WebApplication webApplication) {
IAuthorizationStrategy strategy;
strategy = new ApplicationAuthorizationStrategy(new
UserRolesAuthorizer());
webApplication.getSecuritySettings().setAuthorizationStrategy(strategy);
webApplication.getSessionListeners().add(new
UserScopeInjector());
}
}
public class UserScopeInjector implements ISessionListener {
@SpringBean(name = "userScopeFinder")
private UserScopeFinder userScopeFinder;
public UserScopeInjector() {
super();
Injector.get().inject(this);
}
@Override
public void onCreated(Session session) {
System.out.println("Works");
}
}
But in that case i get:
...

I'm a little bit lost, if my strategy is working in common. Has someone maybe
an example for me?
Thanks for your support
