如何使用spring安全性显示隐藏元素

Question

我有一个按钮，我想显示在登录页面。

因此，当用户登录时，我想隐藏这个按钮。我认为

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

对此很有用，因此我在jsp中包含了如下内容

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

但是在登录页面和登录之后都是不可见的。

有什么问题吗。

<http pattern="/foobar/static-wro4j/**" security="none"/>
<http pattern="/foobar/static/**" security="none"/>
<http pattern="/foobar/login*" security="none"/>
<http pattern="/foobar/syndic/**" security="none"/>
<http pattern="/foobar/register/**" security="none"/>
<http pattern="/foobar/lostpassword/**" security="none"/>

<http auto-config="true" use-expressions="true" create-session="ifRequired">

    <form-login

    <http-basic/>
    <logout logout-url="/foobar/logout"
            logout-success-url="/foobar/login"/>

    <openid-login authentication-failure-url="/foobar/login?action=loginFailure"
                  user-service-ref="openIdAutoRegisteringUserDetailsService">
        <!-- Only Google Apps is supported -->
        <attribute-exchange identifier-match="https://www.google.com/.*">
            <openid-attribute name="email" type="http://axschema.org/contact/email" required="true" count="1"/>
            <openid-attribute name="firstname" type="http://axschema.org/namePerson/first" required="true"/>
            <openid-attribute name="lastname" type="http://axschema.org/namePerson/last" required="true"/>
        </attribute-exchange>
    </openid-login>
</http>

确保在JSP中包含了Spring安全标记库：

<%@ 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>
