java - Hibernate Spring 连接无法 Autowiring

Question

我正在尝试使用 Hibernate 和 Spring 在 OracleDB 上执行一些增删改查操作。 我用 HibernateTools 生成了该类。我创建一个这样的界面:

public interface AssegniDao {

}

和这样的实现

@Repository
@Qualifier("AssegniDao")
public class AssegnoDaoImpl extends AbstractAutowiredDao implements AssegniDao { 

}

这一切都在一个名为“dataLayer”的项目中。在另一个项目中，我使用 Junit 对其进行了测试，但我一直遇到这种错误

nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field

我该如何解决这个问题？

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [it.bnl.btre.orchass.busin.dao.AssegniDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Answer 1

不要忘记先扫描包裹:

<context:component-scan base-package="the.path.to.your.package.with.controller" />

将 Bean 命名为:

@Repository("AssegnoDao")
public class AssegnoDaoImpl extends AbstractAutowiredDao implements AssegniDao { 

}

然后，当您使用@Autowire时，不要忘记指定bean的名称:

@Autowired
@Qualifier("AssegniDao")
private AssegniDao assegniDao;
