我使用 jsp 在 Java 中制作了一个小 web 应用程序,但在登录身份验证方面遇到了一些问题..

  1. 我有 4 个不同的用户。 jsp 页面中有 4 个选项卡

  2. 我需要授予他们对选项卡的有限访问权限。

eg-director(可以看到所有选项卡) 官员 1(只能查看 3 个选项卡的访问权限) 官员 2(只能看到只能访问 2 个选项卡) 官员 3(只能看到只能访问 1 个选项卡)

这就像安全许可我尝试了很多方法但都失败了,我正在考虑通过将 boolean 值传递给数据库并给出访问级别来做到这一点为此,我需要帮助,如果它是一个小样本登录项目,这对我来说非常有帮助

最佳答案

试试这个方法

成功登录后,将用户类型保存在 session 中。然后在jsp中添加以下角色条件。

例如,我们想要阻止“官员 2”访问选项卡 4。
然后在 Tab 4 的 jsp 中添加以下条件。在其他 jsp 中也是如此。

<c:if test="${role== 'officer 2'}">
<jsp: forward page="../invalidAccess.html"/>
</c:if>

或者,您可以使用过滤器来执行相同的操作。过滤器比以前的方式更受欢迎。
