在启动工程的时候出现如下异常：

org.springframework.beans.factory.BeanCreationException: 
　　Error creating bean with name 'userServiceImpl': Injection of autowired dependencies failed; 
　　nested exception is org.springframework.beans.factory.BeanCreationException: 
　　Could not autowire field: private cn.itcast.bos.dao.IUserDao cn.itcast.bos.service.impl.UserServiceImpl.userDao; 
　　nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDaoImpl' 
　　defined in URL [jar:file:/D:/Maven/repository/cn/itcast/bos-dao/1.0-SNAPSHOT/bos-dao-1.0-SNAPSHOT.jar!/cn/itcast/bos/dao/impl/UserDaoImpl.class]: 
　　Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required

　　项目中所有Dao实现类都继承了自定义的BaseDaoImpl，而BaseDaoImpl又继承了HibernateDaoSupport 
　　以前写配置文件时，sessionFactory需要单独配置，现在全注解方式，如何设置sessionFactory呢？ 
　　在BaseDaoImpl中增加如下方法，使用Resource：

//根据类型注入spring工厂中的会话工厂对象sessionFactory
@Resource
public void setMySessionFactory(SessionFactory sessionFactory) {
    super.setSessionFactory(sessionFactory);
}
