我试图在使用 Waffle NTML 进行身份验证时启用 Spring Security 中的角色层次结构投票,但存在一些未知问题,即继承的角色不会像预期的那样显示为主体上的权限,从而阻止拦截 url 中的 hasRole 表达式和使用授权 jsp taglibs .
我一直在根据以下指南集成华夫饼:https ://github.com/dblock/waffle/blob/master/Docs/spring/SpringSecuritySingleSignOnFilter.md
这可以使用标准RoleVoter在应用程序中按预期自行工作,但是当我尝试自定义它以使用我自己也测试过的RoleHierarchyVoter(使用 LDAP 身份验证提供程序)并且角色层次结构完全一样时,问题就开始了预期的。
Waffle 和 RoleHierarchyVoter 组合方法的配置如下:
华夫饼特定配置

<bean id="waffleWindowsAuthProvider" class="waffle.windows.auth.impl.WindowsAuthProviderImpl" />
<!-- collection of security filters -->

<property name="AllowGuestLogin" value="false" />
<property name="PrincipalFormat" value="fqn" />
<property name="RoleFormat" value="fqn" />
<property name="GrantedAuthorityFactory" ref="simpleGrantedAuthorityFactory" />
<!-- set the default granted authority to null as we don't need to assign a default role of ROLE_USER -->
<property name="defaultGrantedAuthority"><null/></property>
</bean>
<!-- custom granted authority factory so the roles created are based on the name rather than the fqn-->
<bean id="simpleGrantedAuthorityFactory" class="xx.yy.zz.SimpleGrantedAuthorityFactory">
<constructor-arg name="prefix" value="ROLE_"/>
<constructor-arg name="convertToUpperCase" value="true"/>
</bean>
