У вас есть 3 варианта, чтобы установить created и updated по умолчанию или сделать created и updated как необязательные, как показано ниже, в зависимости от вашего случая:

Опция 1: установить значение created и updated

public UsersController(UserRepository userRepository) {
        this.userRepository = userRepository;
        User user = new User();
        user.setUsername("admin@admin.com");
        user.setPassword("admin@admin.com");
        user.setActive(true);
        Set<Role> roles = new HashSet<Role>() {{
            add(Role.USER);
        }};
        user.setRoles(roles);
        user.setCreated(new Date());
        user.setUpdated(new Date());


        userRepository.save(user);
}

Опция 2: установить значение по умолчанию 

@Column(columnDefinition = "timestamp default now()")
@DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
private Date created;

@Column(columnDefinition = "timestamp default now()")
@DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
private Date updated;

Опция 3: сделать столбцы обнуляемыми 

@Column
@DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
private Date created;

@Column
@DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
private Date updated;

rootBeanClass=class com.myproject.eshop.model.User, 
messageTemplate='{javax.validation.constraints.NotNull.message}'}`

здесь ваша ошибка, у вас есть ненулевое ограничение, которое вы не выполняете. Так что что-то в User не может быть нулевым при сохранении.
