dao的实现类:
public class S3Impl implements UserDao{ private SessionFactory sessionFactory = null; public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } @Override public boolean create(UserModel um) { Session session = sessionFactory.getCurrentSession(); session.save(um); return true; } }
页面报错:

Acion类请事先ModelDriver接口!!
把你的action贴出来,你的错误可能是action中引用的实体类引起的
<divclass="ref">把你的action贴出来,你的错误可能是action中引用的实体类引起的
user类为空啊,你贴出来的错误已经写得很明显了,看下Struts配置吧<divclass="ref">版权声明:本文内容由阿里云实名注册用户自发贡献,版权归原作者所有,阿里云开发者社区不拥有其著作权,亦不承担相应法律责任。具体规则请查看《阿里云开发者社区用户服务协议》和《阿里云开发者社区知识产权保护指引》。如果您发现本社区中有涉嫌抄袭的内容,填写侵权投诉表单进行举报,一经查实,本社区将立刻删除涉嫌侵权内容。
