Spring Social Login: How to add more than one app of the same social provider (f.e. Facebook)? - spring

Question

My Spring MVC web application is serving simultanously three different web shops with three different domains (let's call them domain1.com, domain2.com and domain3.com).
For each of these shops I need to offer an own Social Login (with custom login screen title, custom data privacy statement, ...). Therefore I need to create three different social provider (f.e. facebook) apps.
In Spring Social - from my understanding - I'm allowed to add only one FacebookConnectionFactory and hereby only one provider app.
How can I despite that add these three different facebook apps to Spring Social? Is Spring Social capable to manage this? Are there workarounds existing?

Answer 1

May be I answered too late for the OP but this could be usefull for other developers.
I implemented a workaround for this issue defining my own "Registries" as follow:
<bean id="myConnectionFactoryRegistries" class="package.ShopsFactoryRegistries">
<property name="registries">
<map key-type="java.lang.String">
<entry key="shop1Key" value-ref="connectionFactoryRegistryShop1" />
<entry key="shop2Key" value-ref="connectionFactoryRegistryShop2" />
</map>
</property>
</bean>
<bean id="connectionFactoryRegistryShop1"
class="org.springframework.social.connect.support.ConnectionFactoryRegistry">
<property name="connectionFactories">
<list>
<bean
class="org.springframework.social.facebook.connect.FacebookConnectionFactory">
<constructor-arg value="${facebook.apikey.shop1}" />
<constructor-arg value="${facebook.apisecret.shop1}" />
</bean>
</list>
</property>
</bean>
<bean id="connectionFactoryRegistryShop2"
class="org.springframework.social.connect.support.ConnectionFactoryRegistry">
<property name="connectionFactories">
<list>
<bean
class="org.springframework.social.facebook.connect.FacebookConnectionFactory">
<constructor-arg value="${facebook.apikey.shop2}" />
<constructor-arg value="${facebook.apisecret.shop2}" />
</bean>
</list>
</property>
</bean>
And implement a factory in order to retrieve the proper ConnectionFactoryRegistry related to the "current" shop (identified by the shopKey).
public class ShopsFactoryRegistries
{
private Map<String, ConnectionFactoryRegistry> registries;
public ConnectionFactoryRegistry getRegistryForShopKey(String shopKey)
{
return registries.get(shopKey);
}
//getter and setter for registries
}
With this code you can retrieve the facebookConnectionFactory for the shop1:
String shopKey = "shop1Key";
FacebookConnectionFactory facebookConnectionFactory = (FacebookConnectionFactory) myConnectionFactoryRegistries.getRegistryForShopKey(shopKey).getConnectionFactory(FACEBOOK);
