Question

How to remove this exception :(

and suggest to tutorial provide, that show each and every step of lecture for beginners because it's don't know what will be next

UserService.java 

    @Service
    public class UserService {

        @Autowired
        private UserRepository userRepository;

        public List<User> findAll(){
            return userRepository.findAll();
        }
    }

usercontroller.java 

@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/users")
    public String users(Model model){
        model.addAttribute("users", userService);
        return "users";
    }
}

InitDbService.java 

    @Transactional
    @Service
    public class InitDbService {

        @Autowired
        private UserRepository userRepository;

        @Autowired
        private RoleRepository roleRepository;

        @PostConstruct
        public void init()
        {
            Role roleUser=new Role();
            roleUser.setName("ROLE_USER");
            roleRepository.save(roleUser);

            Role roleAdmin=new Role();
            roleAdmin.setName("ROLE_ADMIN");
            roleRepository.save(roleAdmin);

            User userAdmin= new User();
            userAdmin.setName("admin");
            List<Role> roles=new ArrayList<Role>();
            roles.add(roleAdmin);
            roles.add(roleUser);
            userAdmin.setRoles(roles);
            userRepository.save(userAdmin);

        }

    }

Rename emf to entityManagerFactory : 

<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">

also, rename TransactionManager to transactionManager : 

<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">

For more details, consult the documentation .
