Question

我想在登录页面显示一个按钮。

因此，当用户登录时，我想隐藏此按钮。我想

<sec:authorize access="isAuthenticated()">

对此有用，所以我在jsp

中包含了类似的内容

<sec:authorize access="not isAuthenticated()">
            <div class="pull-right">

但在登录页面和登录后都不可见。

可能是什么问题。

确保已在JSP中包含Spring Security标记库：

<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>

在您的安全配置中包括：

<beans:bean class="org.springframework.security.web.access.expression.DefaultWebSecurityExpressionHandler"/>

然后使用authorize标记：

<sec:authorize access="isAuthenticated()">
   <!-- Content for Authenticated users -->  
</sec:authorize>

<sec:authorize access="isAnonymous()">
   <!-- Content for Unauthenticated users -->  
</sec:authorize>
