【问题描述】：
我正在使用 Redis 在我的 JEE 项目中实现 spring-session。 HttpSession 正在我的 Redis 服务器上保存和更新，我可以在节点故障转移的情况下使用它。
问题是，我的会话范围 bean 没有与 Redis 中的会话一起保存，因此我不能在集群上使用，因为用户需要存储在 bean 上的信息才能使用很多功能（坚定的）。
我错过了什么吗？我找不到很多关于此的信息，而且由于我是 Spring 新手，所以它会让人感到困惑。 bean（或可以）是否与会话一起存储在 Redis 中？这是我的实现：

您是否认真地在 java-ee 项目中引入 spring 只是为了能够在 redis 中存储 序列化不可读 对象？我刚刚阅读了您关于此问题的其他 Q/A，建议您不要有充分和正当的理由...您的 java-ee 服务器是什么，我确信它具有内置功能。
-
哦，通过添加@Component，您不仅引入了 spring-session，而且引入了完整的 spring 注入/上下文框架。在一个类上同时使用组件和命名注释是错误的......我强烈建议不要这样做

您好 Kukeltje，感谢您的反馈！我正试图在 web 项目上远离 JEE，所以引入 spring 没有问题。当然，正如您所指出的，我忽略了一些重要的实现。我正在使用 Payara。我会看一下幻灯片并给你一个反馈。谢谢！
