Java Spring应用程序中的NoSuchBeanDefinitionException

我正在创建一个使用REST的应用程序。目前，我的控制器正在使用ServiceMockImplementation实现，但我打算使用数据库，而不是硬编码联系人的值。restful客户端工作正常，在模拟实现使用时在服务器上运行，但当我添加DAO实现时，它崩溃并给我一个NoSuchBeanDefinitionException，即使bean contactDao在我的DAO实现类中被注释为@RepositorycontactDao

这是我的RestfulClientMain：

这是我的联系人控制器：

这是我的ContactMock实现。目前，您可以看到它包含硬编码的值，但作为注释，我已经包含了解决此错误后代码实际应该执行的操作。它与DAO交互以从数据库中检索联系人

@Service("contactService")
@Component
public class ContactServiceMockImplementation implements ContactService {

    private Contacts _contacts;

    public ContactServiceMockImplementation() {
        Contact contact1 = new Contact();
        contact1.setId(1L);
        contact1.setVersion(1);
        contact1.setFirstName("Clint");

}

启动服务器时，我得到的错误是：

错误：org.springframework.web.servlet.DispatcherServlet-上下文初始化失败 org.springframework.beans.factory.BeanCreationException:创建名为“contactDao”的bean时出错：注入资源依赖项失败；嵌套异常为org.springframework.beans.factory.NoSuchBeanDefinitionException:未找到依赖项类型为[org.hibernate.SessionFactory]的符合条件的bean：应至少有1个符合以下条件的bean 我目前陷入困境，因为我不太确定如何才能将我的ContactService与我的ContactDao链接起来，而不是使用Mock实现方法。任何帮助都将不胜感激。谢谢

@资源似乎是按名称布线，而不是按类型布线。您可以改用@Autowired，或者如果您真的想坚持使用符合JSR-250的注释，请使用@Resourcename=springSessionFactory。最后一种选择是将bean重命名为sessionFactory，这将修复所有问题

就在我添加的那一刻，将导入行添加到root-context.xml，它似乎可以工作：

<import resource= "classpath:restful-client-app-context.xml"/> 
</beans>

我们可以看一下restful-client-app-context.xml吗？我的第一个猜测是您没有包含DAO。如果您刚刚添加了xml文件，那么ContactDaoImpl在？com.aucklanduni.spring.webservices.services中是什么包呢？未找到符合依赖项要求的[org.hibernate.SessionFactory]类型的bean：至少需要1个符合此依赖项autowire候选项要求的bean。依赖项注释：springSessionFactory不应该仅仅是sessionFactory吗，因为这是@Resource参数名？不幸的是，对于您的3个建议，我仍然得到相同的错误：该错误明确表示没有[org.hibernate.sessionFactory]类型的合格bean。为什么更改bean名称会带来不同？
