Spring security +Jsf2 - spring

Question

I'm newbie at spring security it's my first use to spring security at me APP
My application has developed using jsf2 , primefaces , spring , hibernate
after developing it I'm trying to integrate it with Spring security framework
there are two problems
1- when access any URL from app , my app isn't navigate him to login page
2- when one user logged in and someone else tried to access the application in the same time , he see that someone is logged in and conflicts are happenned and at end throw exceptions meaning there is no new created session for the second user
My applicationContext-Security.xml is
<context:property-placeholder location="classpath:resources/jdbc.properties" />
<!-- For Spring auto wiring -->
<tx:annotation-driven />
<context:annotation-config />
<context:component-scan base-package="main.com.zc.attSys" />
<tx:annotation-driven transaction-manager="hibernateTransactionManager" />
<http use-expressions="true">
<form-login login-page="/pages/courseFeedBack/ask/login.xhtml"
authentication-failure-url="/pages/courseFeedBack/ask/login.xhtml" />
</http>
<authentication-manager>
<authentication-provider user-service-ref="userDetailsService">
</authentication-provider>
</authentication-manager>
</beans:beans>

<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>
