不知道什么原因，tomcat启动时，这个Service里的DAO属性注入失败。源代码未改动。

Question

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'portalServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.online.college.core.consts.service.IConstsClassifyService com.online.college.portal.business.impl.PortalServiceImpl.constsClassifyService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'constsClassifyServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.online.college.core.consts.dao.ConstsClassifyDao com.online.college.core.consts.service.impl.ConstsClassifyServiceImpl.entityDao; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.online.college.core.consts.dao.ConstsClassifyDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

service的jar包没有加载进去吧；如果是本地Eclipse启动，尝试这样解决：

比如 ocPortal，

ocPortal上右击 -》Properties-》Deployment Assembly -》Add-》双击Java Build Path Entries -》选中 Maven Dependencies 

然后再启动项目即可

或者参考教程第3章6节： 如何使用源码

  我也报这个错，我已经选中了Maven Dependencies ，tomcat一直报这个问题

  老师，你的这个接口public interface AuthUserDao 没有实现类啊？这个下载地址也失效了http://git.imooc.com/5556428/s110-5556428.git，我在网站上下的代码好像不全？
