<shiro:hasRole ..> 标签不起作用导致 NoSuchMethodException 异常

Question

你能帮我解决我的问题吗，

我与 Apache Shiro 集成，一旦我使用 shiro:hasRole 标签或其他标签，就会抛出异常：

请注意，我有一个正确的 shiro 配置，其中应用了 shiro 安全性并且资源受到保护，其中用户必须经过身份验证和授权才能访问应用程序资源。

但是一旦我尝试涉及 shiro 安全标签，就会看到异常。

我打开了诸如 HasRoleTag 之类的 shiro java 标签，实际上没有构造函数采用javax.faces.view.facelets.TagConfig 的实例 作为参数！

你能帮我解决这个问题吗？

谢谢。

从 1.2 版开始，Shiro 不支持 JSF。您正在查看的标记是 JSP 标记。 Deluan Quintão 为 shiro 编写了一组 JSF facelet 标签。你可以在这里阅读他关于使用它们的帖子：http://techbeats.deluan.com/apache-shiro-tags-for-jsffacelets

请注意，自 1.3 起，他的作品将正式并入 Shiro。 （确实，已经在后备箱里了）
