Java CRUD存储库的所有方法都返回null

我在SpringDate+jsf上做项目。 我得到了一个奇怪的错误：CRUD存储库的所有方法都返回null

model.Game.java

@Setter
@Getter

public class Game

    private Date start;
    @Column(name = "Дата релиза")
    private Date end;



    public void update(Game new_game)
    {
        this.name = new_game.name;
        this.budget = new_game.budget;
        this.profit = new_game.profit;
        this.number = new_game.number;

        this.platform = new_game.platform;
        this.status = new_game.status;
        this.start = new_game.start;
        this.end = new_game.end;
    }
}

repository.GamesRepository

public interface GamesRepository extends CrudRepository<Game, Long>
{
    Game findByName(String nameGame);
    List<Game> getAllBy();
}

仅满足限制的文本

Spring不可能在对象构造之前在对象上注入字段，因此不能在构造函数中使用这些字段。这是油田注入是一个糟糕选择的众多原因之一

相反，只需将存储库设置为常规构造函数参数。您甚至不需要@Autowired，只要只有一个构造函数可供选择

---

更一般地说，从存储库返回的记录通常由一些持久性系统（如JPA）管理，不应该像您现在这样长期存储。相反，在需要时重新调用findAll，并尽量避免加载整个世界。

原因是：java.lang.NullPointerException:null位于org.xtremebiker.jsfspring.view.Games.Games.java:33~[classes/:na]是的，我知道。但是为什么呢？
