java - Spring Security 子线程上下文

Question

所以我正在使用 Spring Security 开发这个 Spring MVC 应用程序。在某些情况下，我的 Controller 响应时间太长，我一直遇到性能问题。这是由于一种处理方法可以根据某些用户输入处理大量数据。

现在，我一直在与我的团队一起围绕该处理方法对代码进行一些调整，我认为如果不对其进行切片并异步执行每个切片，我们就无法从中获得更好的性能。

问题是，当我尝试使用 java.util.concurrent 中的线程池将其切片并将工作分配给子线程时，我会在这些线程执行时收到有关安全上下文的错误消息。

这是堆栈跟踪的摘录:

我知道从请求中生成线程不是好的做法...但我们此时已无​​计可施，根据我们的测量，每个工作线程所花的时间不应超过几秒钟。此外，预计该功能每周仅供 1 或 2 名专用用户使用一次。

有没有办法将 securityContext 传递给子线程或任何允许这些线程执行的类似方法？

谢谢

Answer 1

当我遇到类似问题时，我找到了两个解决方案:

解决方案 1将 SecurityContextHolder 的策略更改为 MODE_INHERITABLETHREADLOCAL

你可以这样做

<beans:bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <beans:property name="targetClass"
              value="org.springframework.security.core.context.SecurityContextHolder"/>
    <beans:property name="targetMethod" value="setStrategyName"/>
    <beans:property name="arguments" value="MODE_INHERITABLETHREADLOCAL"/>
</beans:bean>

解决方案 2 使用 DelegatingSecurityContextRunnable、DelegatingSecurityContextExecutor 或 DelegatingSecurityContextExecutor。 Spring Concurrency Support Documentation 中详细描述了此解决方案
