解决方案 »

  1.   


    public class UserDAO extends BaseDAO<User> implements IUserDAO{
    private static HibernateTemplate template;
    private SessionFactory sessionFactory;
    public void setSessionFactory(SessionFactory sessionFactory) {
    template = new HibernateTemplate();
    }
      

  2.   

    没有注入sessionFactory，你spring的配置文件里面配了这个sessionFactory，但是你通过set方法注入时候，首先要声明它啊
      

  3.   

    而且配置文件中要加上default-autowire="byName"，这样spring才会通过配置的bean id去初始化对象
      

  4.   

    我配置了property,不就不需要加default-autowire="byName"了吗？
    还有就是，我加了default-autowire="byName"还是出了一样的错误
    ps：我初学框架，不懂的很多，谢谢帮助！
      

  5.   

    楼主 看看你着几句代码
    template = new HibernateTemplate();这样 new 出来的 HibernateTemplate() 和你注入的 sessionFactory 没有一点关系啊
    最起码要加上 template.setSessionFactory(sessionFactory);吧？？
