【问题描述】：

我有以下sn-p

<http use-expressions="true" auto-config="false"
        entry-point-ref="loginUrlAuthenticationEntryPoint"
        access-decision-manager-ref="accessDecisionManager" disable-url-rewriting="false">
        <!--<custom-filter position="CONCURRENT_SESSION_FILTER" ref="concurrencyFilter"
            /> -->
        <custom-filter position="FORM_LOGIN_FILTER"
            ref="usernamePasswordAuthenticationFilter" />
        <custom-filter position="LOGOUT_FILTER" ref="tapLockFilter" />

        <intercept-url pattern="/session/**" access="permitAll" />
        <intercept-url pattern="/deviceregistration/**" access="permitAll" />
        <intercept-url pattern="/session/lock" access="hasRole('ROLE_MEMBER')" />
        <intercept-url pattern="/app/resources/admin*" access="hasRole('ROLE_ADMIN')" />
        <intercept-url pattern="/app/SuperAppdashboard*" access="hasRole('ROLE_ADMIN')" />
        <intercept-url pattern="/app/*" access="hasRole('ROLE_MEMBER')" />


        <!--<session-management invalid-session-url="/tizelytics/session/invalidSession"
            session-authentication-error-url="/tizelytics/session/accessDenied" session-authentication-strategy-ref="sas">
            </session-management> -->

        <session-management invalid-session-url="/session/invalidSession"
            session-authentication-error-url="/session/accessDenied"
            session-fixation-protection="none">
            <concurrency-control max-sessions="1"
                expired-url="/session/accessExpired" />
        </session-management>
</http>

当我在服务器上运行它时，它会抛出一个异常提示

不支持的配置属性：[permitAll, permitAll, hasRole('ROLE_ADMIN'), hasRole('ROLE_ADMIN'), hasRole('ROLE_MEMBER'), hasRole('ROLE_MEMBER')]

这是我在同一个 xml 中的 access-decision-manager bean

<beans:bean id="accessDecisionManager"
        class="org.springframework.security.access.vote.AffirmativeBased">
        <beans:constructor-arg>
            <beans:list>
                <beans:bean
                    class="org.springframework.security.access.vote.AuthenticatedVoter" />
                <beans:bean class="org.springframework.security.access.vote.RoleVoter" />
            </beans:list>
        </beans:constructor-arg>
</beans:bean>

如果我删除 access-decision-manager-ref 不会引发异常，应用程序会正确启动，有人可以请教吗？

【问题讨论】：

AccessDecisionManager 用于基于旧字符串的访问条件定义。您正在使用基于表达式的评估，因此您不需要它。

【解决方案1】：

由于您正在定义自己的accessDecisionManager，我不认为WebExpressionVoter 是其列表中的bean 之一。 WebExpressionVoter 解析 permitAll()、hasRole()、hasAuthority() 等字符串。所以，你的 accessDecisionManager bean 应该是：

<beans:bean id="accessDecisionManager"
        class="org.springframework.security.access.vote.AffirmativeBased">
        <beans:constructor-arg>
            <beans:list>
                <beans:bean
                    class="org.springframework.security.access.vote.AuthenticatedVoter" />
                <beans:bean class="org.springframework.security.access.vote.RoleVoter" />
                <beans:bean class="org.springframework.security.web.access.expression.WebExpressionVoter" />
            </beans:list>
        </beans:constructor-arg>
</beans:bean>
