Question

创建名称为'trangchuController'的bean时出错：通过字段'sessionFactory'表示的不满意的依赖关系；嵌套的异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有可用的类型为org.hibernate.SessionFactory的合格Bean：至少应有1个可以作为自动装配候选的Bean。依赖注释：{@ org.springframework.beans.factory.annotation.Autowired（required = true）}

通过字段“ sessionFactory”表示不满意的依赖关系；嵌套的异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：
