Spring boot Spring会话的建议Infinispan缓存模式

我的应用程序通过使用Infinispan的Spring会话实现。我通过InfinispanEmbeddedHttpSessionConfiguration使用嵌入式模式。这是非常稀疏的，它没有提到任何关于会话缓存的推荐缓存模式的内容

我一直在使用DIST_SYNC模式，但我注意到日志中偶尔出现ConcurrentModificationException错误。是否有更合适的缓存模式，或者这可能是一个bug

我使用的是Spring Boot 2.2.10、Infinispan 9.4.20和Spring Session 2.2.0。该应用程序在JDK 11下运行

编辑

我在日志中观察到的例外情况如下。我放了xxx。代替我公司的过滤器包名

当同一个会话连续快速重复使用时会出现异常，特别是当我们的外部安全供应商每周对我们的应用程序进行扫描时。这种例外情况并非每周都发生。当它确实发生时，会在未获取ConcurrentModificationException的节点上导致最终的OutOfMemory错误。堆中充满了TrianglePerCacheInboundInvocationHander$1对象

我试图在我们的开发环境中通过运行并发请求3天来重现错误，但没有成功

我查看了Infinispan Spring会话代码，发现每个请求都有自己的MapSession实例，这些实例是从Infinispan中存储的序列化数据中实现的。我不知道同一会话的多个并发请求如何导致ConcurrentModificationException，我也不知道我的应用程序中有任何地方允许从多个线程并发访问MapSession实例

在会话中使用DIST_SYNC模式应该可以

如果在序列化会话属性时抛出ConcurrentModificationException，则表示应用程序在将属性值插入会话后正在修改属性值，而不应这样做

如果在序列化会话本身时发生ConcurrentModificationException，那么很可能是Infinispan-Spring会话集成中的错误。 如果ConcurrentModificationException与序列化完全无关，则相同。我建议在你的问题中发布完整的堆栈跟踪，或者注册一个帐户并在那里发布异常

---

最后请注意，Infinispan 9.4.20已经很老了，最终的错误修复可能只会在Infinispan 12.x中实现。

谢谢Dan。我已经更新了问题以包含例外情况。如果你认为这会更容易的话，我很高兴将讨论转移到Zulip聊天。谢谢stacktrace@Nathan。看起来您遇到的不是一个错误，而是两个错误：这意味着Infinispan正在整理会话，而另一个请求正在修改它，然后导致OOME。一个可能的解决方法是在MaxSimultaneousRequestsFilter中同步会话对象。再次感谢Dan。我没有查看ISPN-12435的权限，但从您的回答来看，我认为它只能在12.x或更高版本中修复。我会将应用升级到12.x，这样我就可以在错误修复就绪时应用它们。谢谢Dan。我已经更新了问题以包含例外情况。如果你认为这会更容易的话，我很高兴将讨论转移到Zulip聊天。谢谢stacktrace@Nathan。看起来您遇到的不是一个错误，而是两个错误：这意味着Infinispan正在整理会话，而另一个请求正在修改它，然后导致OOME。一个可能的解决方法是在MaxSimultaneousRequestsFilter中同步会话对象。再次感谢Dan。我没有查看ISPN-12435的权限，但从您的回答来看，我认为它只能在12.x或更高版本中修复。我将把应用程序升级到12.x，这样我就可以在bug修复就绪时应用它们。
