i have made a little webapp in Java using jsp and am having a little problem with Login Authentication.. 我已经使用jsp在Java中制作了一个小的webapp，并且登录身份验证遇到了一些问题。
i have 4 different users.
我有4个不同的用户。 have 4 tabs in a jsp page 一个jsp页面中有4个选项卡 i need to give them the limited access to Tabs.
我需要给他们有限的标签访问权限。
eg-director (can see all the tabs) officer 1 (can see only have accesses to 3 of tabs ) officer 2 (can see only have accesses to 2 of tabs ) officer 3 (can see only have accesses to 1 of tabs ) 例如，主任（可以看到所有选项卡）主任1（只能看到3个选项卡的访问权限）主任2（只能看到2个选项卡的访问权限）主任3（只能看到1个选项卡的访问权限）
it is like a security clearance i tried to so many ways and failed and i am thinking to do that with passing a Boolean to Database and give the access levels for that i need a help if it is with a small sample log in project that will be very help full for me 这就像一个安全检查，我尝试了很多方法但都失败了，我正在考虑通过将布尔值传递给数据库并为此提供访问级别来实现这一点，如果它是一个小型示例登录项目，非常帮我忙

Try this way out, 尝试这种方式，
After successful login, save user type in session. 成功登录后，将用户类型保存在会话中。 Then in jsp add following conditions for role. 然后在jsp中添加以下角色角色。
let's say for example, We want to block access of Tab 4 for 'officer 2'. 举例来说，我们要禁止访问“人员2”的选项卡4。
Then in jsp for Tab 4 , add below condition. 然后在用于选项卡4的jsp中，添加以下条件。 and like wise in other jsp's also. 就像其他jsp中的明智者一样。
<c:if test="${role== 'officer 2'}">
<jsp: forward page="../invalidAccess.html"/>
</c:if>
alternatively, You can make use of Filters to do same. 或者，您可以使用过滤器执行相同的操作。 Filters are more preferred over earlier way. 过滤器比早期方法更可取。
