Problem: my UserService in IndexController.java don't autowired! And i was added "sessionFactory" and it don't autowired too. "SessionFactory" is only null and when i write annotation to UserService i have next stacktrace (from jsp):

I don't understand why I can't get this UserService and my sessionFactory is null.

Answer 1

Seems like the problem with the application-context.xml naming.
So, Ensure that the file applicationContext.xml exists with proper name (should not be application-context.xml) in the WEB-INF folder so that the sessionFactory bean will be loaded. Otherwise, the sessionFactory bean object will be null.

Answer 2

Error was in
private UserService userService;
UserService is class and not interface. I create interface UserServiceI (UserService is implement UserServiceI) and write in IndexController
#Autowire
private UserServiceI userService;
All works!
