我正在使用SpringBoot + Hibernate。
Spring依赖项在Controller和Service Project中
休眠依赖项位于存储库项目中
我将SpringBoot配置为与数据库连接，但是我无法将Repository注释为spring的一部分，因为Spring依赖项不在Repository Project中，并且我无法在其中添加它们，这是因为我的老板不想
控制器调用一个服务，该服务向存储库询问客户列表，然后存储库尝试使用实体管理器通过查询从数据库中获取它。
这是我得到的错误

我的项目中有hibernate-jpa-2.0-api-1.0.1.Final.jar
我配置了persistence.xml并在类中注入了@PersistenceContext注释
我仍然收到此错误
似乎找不到EntityManager，但我不明白为什么
public class ProvaDaoImpl{
@PersistenceContext(unitName="hooda")
EntityManager em;
public List<BiUserCustomer> list() {
Query q = em.createNativeQuery("SELECT * FROM BI_CC");
List<BiUserCustomer> lista = q.getResultList();
return lista;
}
}
