Java – JSTL标签中的Spring安全开关案例

有没有办法转换窗体的jsp代码

ecurity:authorize access="hasRole('ROLE_USER')">You're an userecurity:authorize>
ecurity:authorize access="hasRole('ROLE_ADMIN')">You're an adminecurity:authorize>
ecurity:authorize access="hasRole('ROLE_SADMIN')">You're a superadminecurity:authorize>

到另一种形式,类似于以下(不起作用)？

更确切地说,有没有办法用JSTL标签替换这个Spring Security taglib功能？

最佳答案

您可以使用< security：authorize />的var属性.标签将创建：

A page scoped variable into which the boolean result of the tag
evaluation will be written,allowing the same condition to be reused
subsequently in the page without re-evaluation.

ecurity:authorize access="hasRole('ROLE_USER')" var="isUser" />
ecurity:authorize access="hasRole('ROLE_ADMIN')" var="isAdmin" />
ecurity:authorize access="hasRole('ROLE_SADMIN')" var="isSuperUser" />
