How to share Objects between mutliple Providers?
#41509
The following code works but can anyone recommend a better way to achieve the same thing?
The following code allows sharing Objects between mutliple Providers like Authenticators:
SharedObjectProvider {
static HashMap providers = new HashMap()
static SharedObjectProvider getOrCreateSharedObjectProvider(RealmModel realm, ComponentModel config) {
synchronized (providers) {
SharedObjectProvider provider = providers.get(realm.getId()) // limit scope to per-realm
if (provider == null) {
provider = new SharedObjectProvider()
provider.sharedObject = ... load object to share such as from a file perhaps ...
providers.put(realm.getId(), provider)
}
return provider;
}
}
Object sharedObject
Object getSharedObject() { return sharedObject }
}
This example shares Objects between a UserStorageProvider and Authenticator (or multiple related Authenticators in my case):
MyUserStorageProviderFactory implements UserStorageProviderFactory<MyUserStorageProvider> {
MyUserStorageProvider create(KeycloakSession session, ComponentModel config) {
// trigger shared object to be created using UserStorageProvider config
SharedObjectProvider.getOrCreateSharedObjectProvider(session.getContext().getRealm(), config)
return new MyUserStorageProvider()
}
}
Now the shared Object(s) can be retreived elsewhere such as within an Authenticator:
MyAuthenticator extends AbstractUsernameFormAuthenticator implements Authenticator {
authenticate(AuthenticationFlowContext context) {
RealmModel realm = context.getRealm();
ComponentModel config = realm.getStorageProviders(UserStorageProvider.class).findFirst().get();
// now get shared object loaded in UserStorageProvider.create
SharedObjectProvdier provider = SharedObjectProvider.getOrCreateSharedObjectProvider(realm, config);
Object sharedObject = provider.getSharedObject()
// and maybe use shared provider in other ways...
}
}
I thought maybe I could just do componentModel.setNote("my.shared.object", sharedObject) but calling getNote() elsewhere returns null (even though getId() was the same).
Is there a better way to share Objects between multiple Providers per-realm?
