【问题描述】：

我正在使用 Spring3.1.1 和 hibernate4 来实现 Spring MVC 项目在尝试使用 Hibernate 获取数据时，我收到以下错误

ERROR [org.springframework.web.servlet.DispatcherServlet] (http--127.0.0.1-8080-1) Context initialization failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'homeController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.xxx.service.ContactService com.vedic.stp.HomeController.contactService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.xxx.service.ContactService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

控制器代码：

@Controller
public class HomeController {

    private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
    @Autowired
    private ContactService contactService;
    /**
     * Simply selects the home view to render by returning its name.
     */
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(Locale locale, Model model) {
        logger.info("Welcome home! The client locale is {}.", locale);
        System.out.println("The is callessing service");
        Date date = new Date();
        DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
        logger.info("The list size is----"+contactService.listContact());
        String formattedDate = dateFormat.format(date);
        model.addAttribute("serverTime", formattedDate );

        return "home";
    }

}

服务类：

@Service
public class ContactServiceImpl implements ContactService {

    @Autowired
    private ContactDAO contactDAO;

    @Transactional
    public void addContact(Contacts contact) {
        contactDAO.addContact(contact);
    }

    @Transactional
    public List<Contacts> listContact() {

        return contactDAO.listContact();
    }

    @Transactional
    public void removeContact(Integer id) {
        contactDAO.removeContact(id);
    }
}

Servlet 上下文文件：

<?xml version="1.0" encoding="UTF-8"?>

        <beans:property name="suffix" value=".jsp" />
    </beans:bean>

    <context:component-scan base-package="com.xxx.stp" />
</beans:beans>

我是 Spring 和 Hibernate 的新手。请帮我解决这个错误。

【问题讨论】：

No matching bean of type [com.srisys.service.ContactService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency - 这就是问题
你在注册 bean ContactService 吗？
发布 spring xml 文件以获得更多帮助！！
感谢 shikjohari 的回复，我不知道如何注册 bean 请提供我必须注册的信息

【解决方案1】：

因为您在 servlet 上下文文件中的控制器 bean 配置代码是错误的。如下声明。

<!-- this package must be your controller package -->
        <context:component-scan base-package="com.xxx.stp" />

如果你的包名是真的，你需要在com.xxx.stp中包含所有子包：我想。

<!-- this package must be your controller package -->
            <context:component-scan base-package="com.xxx" >
              <context:include-filter type="aspectj" expression="com.xxx.*" />
            </context:component-scan>
