I have succesfully applied how to integrate facebook user logins with facebook based on this article, which revolves around creating a custom auth-token, realm, auth info and an empty credential-matcher for facebook.
The problem i'm having right now is that although i can successfully do a login, i cannot seem to get the session started, as can be seen from my custom session storage. Note that using the 'normal-non-facebook' login works, the sessions are created.
My guess is that the problem has something to do with shiroFilter + the loginUrl being able to create the native session, and manually doing SecurityUtils.getSubject().login(token) cannot create the native session.
When i do this in hope to create the session after login manually :
SecurityUtils.getSubject().login(facebookToken);
SecurityUtils.getSubject().getSession(true);
I get this exception :
org.apache.shiro.subject.support.DisabledSessionException: Session creation has been disabled for the current subject. This exception indicates that there is either a programming error (using a session when it should never be used) or that Shiro's configuration needs to be adjusted to allow Sessions to be created for the current Subject. See the org.apache.shiro.subject.support.DisabledSessionException JavaDoc for more.
Here's my session related configs :
<bean id="sessionManager" class="org.apache.shiro.web.session.mgt.DefaultWebSessionManager">
<property name="globalSessionTimeout" value="xxx" />
<property name="sessionDAO" ref="sessionDAO" />
<property name="sessionValidationSchedulerEnabled" value="false" />
<property name="sessionIdCookie.domain" value="xxx.com" />
</bean>
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="sessionMode" value="native" />
<property name="realms">
<list>
<ref bean="mainRealm" />
<ref bean="fbRealm" />
</list>
</property>
<property name="sessionManager" ref="sessionManager" />
</bean>
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="securityManager" ref="securityManager"/>
<property name="loginUrl" value="/login"/>
<property name="successUrl" value="/"/>
<property name="unauthorizedUrl" value="/signup"/>
<property name="filterChainDefinitions">
<value>
/login = ssl, authc
/logout = noSessionCreation, logout
/** = noSessionCreation, anon
</value>
</property>
</bean>
<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="staticMethod" value="org.apache.shiro.SecurityUtils.setSecurityManager"/>
<property name="arguments" ref="securityManager"/>
</bean>
So in the end, how should i login in a way that automatically creates the session and returns the session cookie to the browser ?
It was the noSessionCreation filter that causes the exception.
I had to do req.setAttribute(DefaultSubjectContext.SESSION_CREATION_ENABLED, Boolean.TRUE);
before doing the manual login to get the session created.
Now everything is working great !
