春季：保存已登录的用户会话

Question

I don't understand where the current logged in user is saved in the application. I want to save the user (after his login) in my spring application. I use Spring Security and already read about the SecurityContextHolder but the problem is I have a custom user class, which is saved in a mongodb. I could query the user from the database after login (check the password and so on), but what are the next steps?

Greetings Chryb

EDIT:

My bigger question is how I should combine my user repository with my login?

Look at my other question for more details here

Answer 1

Finally I have it! This guide was a good help. The extra point is to write

@Override
public void init(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(mongoSecurityService);
}

if you don't use .xml configuration. I have special thanks to guys who don't help answer the question and only flame the post like RC.
