java - Struts2 + Spring Security 2.06：尝试在 Action 方法上使用 @Secured 时，Valuestack 为空

Question

在开始之前，我必须说我找到的最接近的答案是这里，但老实说，我真的不明白那里发生了什么。

我正在使用带有自定义身份验证提供程序和访问决策管理器的 Struts2 + Spring Security 2.06，以消除对“ROLE_”前缀的需要。

我的 applicationContext-security.xml 看起来像这样：

    <beans:bean id="customAuthenticationProvider"
                class="com.test.testconsole.security.CustomAuthenticationProvider">
        <beans:property name="userManagementService" ref="userManagementService"/>
        <custom-authentication-provider/>
    </beans:bean>

    <!--Customize Spring Security's access decision manager to remove need for "ROLE_" prefix-->
    <beans:bean
            id="accessDecisionManager"
            class="org.springframework.security.vote.AffirmativeBased">
        <beans:property name="decisionVoters">
            <beans:list>
                <beans:ref bean="roleVoter"/>
                <beans:ref bean="authenticatedVoter"/>
            </beans:list>
        </beans:property>
    </beans:bean>

    <beans:bean
            id="roleVoter"
            class="org.springframework.security.vote.RoleVoter">
        <beans:property name="rolePrefix" value=""/>
    </beans:bean>

    <beans:bean
            id="authenticatedVoter"
            class="org.springframework.security.vote.AuthenticatedVoter">
    </beans:bean>

<global-method-security secured-annotations="enabled" access-decision-manager-ref="accessDecisionManager"/>

我的 web.xml 的相关部分：

    <!--Spring Security-->
<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>
        org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
    </filter-class>
</filter>

<!--Has to be placed _Before_ the struts2 filter-mapping-->
<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

我只是在我的一个动作类中使用@Secured，如下所示：

@Secured({"TEST_ADMIN"})
public String editAccount() {
    logger.info("Editing account for: " + email);
    //blah blah blah
}

将@Secured注解添加到action中的方法后，所有参数都变为null，实际上看起来valuestack为null：

我在 Spring Security FAQ 中读到 Controller/Action 不是保护方法的最佳位置，但 FAQ 中描述的失败是 @Secured 注释不起作用，即方法将不被保护。

就我而言，我什至在到达该方法之前就得到了一个空值堆栈；execute() 不安全，只有 editUser() 甚至还没有被调用。

我希望有人有相同的经验并找到解决方案..谢谢。

更新： 我想知道这是否会有所帮助：Spring Security - 我如何启用方法安全注释？

我的 Action 类目前扩展了一个 BaseAction 类，但我在其中放置了常用功能..

Answer 1

我只是想知道，如果您使用 Spring Security 的默认配置，则会出现此问题，它需要ROLE_前缀名称。

看到这个问题： 如何在 Spring Security 中使用自定义角色/权限？

您正在使用默认配置，希望角色以“ROLE_”前缀开头。您必须添加自定义安全配置并将 rolePrefix 设置为“”

示例配置来自：Spring Security Role Prefix and Custom User Details Service

<beans:bean id="roleVoter" class="org.springframework.security.access.vote.RoleVoter">
    <beans:property name="rolePrefix" value="" />
</beans:bean>

Answer 2

堆栈跟踪指示“header.jsp”文件中的问题，其中标记存在问题。我怀疑你只是对标签中的表达式有一个空指针问题。你能分享一下 header.jsp 的 JSP 片段吗？

Answer 3

这不会直接回答您的问题，但是如果您使用带有注释的 Spring 3 MVC 控制器并使用匹配的 Spring Security 版本，那么您的集成时间会容易得多。这将为您带来额外的好处，即能够更快地开发它，放弃控制器的 XML 配置，并且只需几分钟即可切换。根据您实施的程度，这可能是一种选择。通常，Spring 注释仅在它们位于 Spring 托管 bean 中或您在编译或运行时将依赖项编织到非 Spring 类中时才起作用。

Answer 4

我已经做过这样的项目。我使用了 Struts 2、Spring 3.0.0 和 Spring Security。

我认为您可以尝试使用@org.springframework.stereotype.Controller 注释struts 动作......这是Spring 管理您的Struts 动作的当前方式。我认为它将解决您相关的弹簧安全问题。

我记得这个架构的另一个特点。在 web.xml 中，您必须在 Struts 2 过滤器之前设置 spring 侦听器和过滤器。我找到了我的旧项目，我的 web.xml 是这样的：

<?xml version="1.0" encoding="UTF-8"?>
