Question

我对Spring有这个问题。我无法理解什么不去。应该是autowired属性的问题，我还咨询了网站上的其他指南，但没有成功。

    // plus getter and setter

Answer 1

你遗失了几件事：

1.将@Entity和@Table添加到实体（共享的项目中缺少）：

@Entity
@Table
public class Abilitazione 



@Entity
@Table
public class Dipendente

2.更换存储库定义，如下所示：

public interface AbilitazioneRepository extends JpaRepository<Abilitazione, Long>{

 Dipendente findByDipendenteId(Long dipendenteId);
}

pom.xml中spring数据和hibernate依赖项之间存在很多依赖冲突。

Spring Autowired“不是托管类型”
