spring - 如何使用 spring 配置 Hazelcast 以进行 session 缓存，同时将其限制为一组节点？

标签 spring session spring-mvc hazelcast

我需要使用 Spring 设置 Hazelcast session 缓存。使用 hazelcast 文档中的配置很简单。然而，这还不够。我需要为我的每个环境(DEV、QA、PROD)使用不同的配置文件。或者(理想情况下)，我想使用在 spring 容器初始化期间设置的 spring bean 的几个属性。根据 hazelcast 文档，我需要做的就是为我的每个环境设置一个组。像这样:

<hazelcast>
    <group>
       <name>dev</name>
       <password>dev-pass</password>
   </group>
   ...
</hazelcast>

作为奖励，我希望缓存是用于 session 和应用程序级对象( map 、队列等)的单个缓存。

任何人都可以分享他们如何做到这一点的例子吗？感谢您的帮助。

最佳答案

感谢您提供建议的答案。但是，我想我已经使用以下配置解决了这个问题。如果有人对此配置提供任何反馈，我将不胜感激。

我的方法:

1) 使用spring配置建立实例。 2) 使用具有 Web 过滤器配置的最低限度配置的 hazelcast.xml 文件增强实例。请注意，mulitcast 和 tcp-ip joiners 是错误的。
