我有一个小应用学习Struts2 Application
我写了一个管理页面,在里面,我的代码将检查用户是否登录,如果没有,它将重定向到登录页面。
我编写拦截器来检查用户尝试访问但未登录的所有页面,它将将此用户重定向到登录页面。一切正常,但是当我在数据库中输入正确的用户名和密码时,它无法登录,当我删除拦截器时,我可以登录到管理页面
原因可能是拦截器在登录之前和之后检查用户的会话,但也许在某些情况下,我不知道为什么我的应用程序会话为空,尽管我的用户名和密码是真实的,但是当我设置会话时它直到为空。
下面的代码将向您展示我所说的:
登录操作

当我输入正确的用户名和密码匹配到数据库时,直到重定向到 login.jsp 页面
我对此一无所知
请帮我
非常感谢
