Hello,
Im new to Spring and Hibernate in general and I am trying to create my first small webapplication.
I am using Spring MVC, Spring Security and Hibernate.
I have a login page, a register page and links for users and admins. Registering does not work because I waited with implementing it until I use Hibernate.
Well, I have two really dumb questions, but I hope that you can help me.
I configured my dataSource-beans and the hibernate stuff (except the hibernate.cfg.xml) in my security-config.xml. Ive got a SessionFactory there. Then I have a class called HibernateDao which extends HibernateDaoSupport. There I can call getHibernateTemplate() and do some actions. This class HibernateDao which is referenced with my SessionFactory is configured also as a bean in my security-config.
And that is my problem. From another class, for example my RegisterController.java, I dont know how to access this bean!!! Its really stupid, I guess, but please tell me how to do it!!
The other question I have is according spring security authentication manager: is the configuration <sec:
jdbc-user-service data-source-ref="securityDataSource"/> right?
and, which now comes in my mind - is class="org.apache.commons.dbcp.BasicDataSource" the right to use for my dataSource?
Please help me with my dumb questions and please, if you see another mistake or if you could give me an advice in how to develope such applications better (or easier)- please tell me.
Here are some of my configurations: (I tried to mark the most important things so that it is easier to look through) (I actually noticed that marking things in code does not work. Well, I let the {b}s there so you can see what I would have marked - maybe easier although its not written fat.... )
