shiro+ssm项目无法访问jsp，目前怀疑shiro配置有问题导致无法注入，但不知道从何下手，大神求解

Error creating bean with name 'shiroDbRealm': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.dnake.cloudparking.service.UserService com.dnake.cloudparking.auth.AuthRealm.userService;
上述为与shiro有关的报错信息以及shiro.xml中我认为有用的内容
Error creating bean with name 'userService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.dnake.cloudparking.dao.UserDao com.dnake.cloudparking.service.impl.UserServiceImpl.userDao;
这段报错信息应该是自动注入报错的地方
我的UserSercieImpl是以@Service注解的
在UserDao 类上加上@Repository注解没有用。。
我的UserDao是接口

求大神解答，实在搞不定
