Spring 3.2长时间轮询导致清除了SPRING_SECURITY_CONTEXT

发布时间：2020-12-15 01:21:42 所属栏目：大数据 来源：网络整理
导读：我正在使用Spring 3.2 Milestone 1来实现long polling的服务.但是由于某些原因,Spring Security(3.1.2)会在第一个延迟结果过期(达到asynctimeout并且tomcat响应http.200)后立即清除SPRING_SECURITY_CONTEXT.一些响应被发送回客户端.使用Spring Security 3.1.

我正在使用Spring 3.2 Milestone 1来实现long polling的服务.但是由于某些原因,Spring Security(3.1.2)会在第一个延迟结果过期(达到asynctimeout并且tomcat响应http.200)后立即清除SPRING_SECURITY_CONTEXT.一些响应被发送回客户端.使用Spring Security 3.1.0只会在某些情况下发生(HTTPS和客户端位于某些硬件防火墙之后),而对于3.1.2来说,它总是会发生(在满足第一个DefferedResult之后)！

这是日志相关部分的调试输出

如果仔细查看输出,将看到第一个长轮询请求“ / updates / events？”.已正确处理-授予访问权限,但随后会清除spring安全上下文,如您从“ HttpSession为SPRING_SECURITY_CONTEXT返回HttpSession返回空对象”行中看到的那样,它是由第一个URL过期后客户端对该URL的另一个请求触发的事件触发非空响应.
我想在这里指出,我所有的自定义过滤器均已禁用,并且在处理长轮询请求时,我将DefferedResult存储到Map中,其中sessionId-clientid(对于每个页面实例浏览器选项卡都是唯一的)作为访问它的键,在收到JMS消息的情况下将结果发送给客户端.

Spring框架3.2 M1和最新的3.2快照版本与Spring Security 3.1.2或其在Tomcat 7.0.28 / 7.0.29(默认和APR连接器)下各自最新的快照结合使用时出现此问题.

最佳答案
借助调试器,我得出了以下结论：

设置DefferedResult后,将调用org.springframework.security.web.context.SaveContextOnUpdateOrErrorResponseWrapper的flush()方法,该方法通过代理调用org.springframework.security.web.context.HttpSessionSecurityContextRepository的saveContext().

@Override
protected void saveContext(SecurityContext context) {
    final Authentication authentication = context.getAuthentication();
    HttpSession httpSession = request.getSession(false);

    // See SEC-776
    if (authentication == null || authenticationTrustResolver.isAnonymous(authentication)) {
        if (logger.isDebugEnabled()) {
            logger.debug("SecurityContext is empty or contents are anonymous - context will not be stored in HttpSession.");
        }

        if (httpSession != null && !contextObject.equals(contextBeforeExecution)) {
            // SEC-1587 A non-anonymous context may still be in the session
            // SEC-1735 remove if the contextBeforeExecution was not anonymous
            httpSession.removeAttribute(springSecurityContextKey);
        }
        return;
    }

由于身份验证对象为空(由于已清除spring安全上下文,因此该行)
httpSession.removeAttribute(springSecurityContextKey)从会话中删除SPRING_SECURITY_CONTEXT,并且该用户在没有安全上下文的会话中导致下一个请求结果,因此将用户重定向到登录名.
除非我在这里缺少明显的东西,否则这是异步请求的破坏者.我想知道Spring Security团队是否知道这个问题,是否计划在3.2发布之前修复它.
同时,是否有人对适当的解决方案有任何建议？

编辑：目前,作为临时解决方案,我通过在异步请求的情况下不编辑会话来解决此问题.具体来说,我修改了从以下位置刷新securityContext的检查：

if (httpSession != null && !contextObject.equals(contextBeforeExecution))

至

if (httpSession != null && !contextObject.equals(contextBeforeExecution) && this.request.getAttribute("javax.servlet.async.request_uri") == null)

谢谢
