将项目发布到服务器时遇到问题，我已经尝试了该站点的几种解决方案，但无法使其正常工作，我已经安装了所有批注，并且XML配置也已正确完成。

UserController.java 

@Controller
@RequestMapping("/user")
public class UserController {

@Autowired
private UserServiceIface userService;

@RequestMapping(value="/home")
public String home(ModelMap model, Authentication authentication) {

    authentication.getPrincipal();
    model.addAttribute("user", userService.getUser(authentication.getName()));

    return "user-info";
}

public String error() {
    return "access-denied";
}
}

UserServiceImpl.java 

@Service
public class UserServiceImpl implements UserServiceIface{

@Autowired(required=true)
@Qualifier("userDAO")
private UserDAOIface userDAO;

@Override
public UserEntity getUser(String userName) {
    return userDAO.getUser(userName);
}

}

UserDAOImpl.java 

@Repository
@Transactional
public class UserDAOImpl implements UserDAOIface{

@Autowired
private SessionFactory sessionFactory;

public UserEntity getUser(String userName) {
    return sessionFactory.getCurrentSession().get(UserEntity.class, 
userName);
}
}

UserDetailsS​​erviceImpl 

@Service
public class UserDetailsServiceImpl implements UserDetailsService{

@Autowired
@Qualifier("userDAOService")
private UserDAOIface userDAO;

@Override
public UserDetails loadUserByUsername(String username) throws 
UsernameNotFoundException {
    UserEntity user = userDAO.getUser(username);

    UserBuilder userBuilder = null;

    if(user != null) {
        userBuilder = User.withUsername(username);
        userBuilder.password(user.getPassword());
        userBuilder.authorities(user.getRole());
    }else {
        throw new UsernameNotFoundException("User not found");
    }

    return userBuilder.build();
}

}
