javax.servlet.ServletException：servlet调度程序的Servlet.init（）   引发异常根本原因

org.springframework.beans.factory.UnsatisfiedDependencyException：   创建名为'pageController'的bean时出错：不满意的依赖项   通过字段'categoryDAO'表示;嵌套异常是   org.springframework.beans.factory.UnsatisfiedDependencyException：   创建名为'categoryDAOImpl'的bean时出错：不满意   通过字段'sessionFactory'表示的依赖;嵌套异常   是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有   'org.hibernate.SessionFactory'类型的限定bean可用：   预计至少有1个豆有资格成为autowire候选人。   依赖注释：   {@ org.springframework.beans.factory.annotation.Autowired（所需=真）}   根本原因
