ApplicationEventMulticaster 未使用 mongo 的 spring-data 初始化

Question

当我的 spring 应用程序启动时，我目前遇到以下异常：

背景：

• 我的 spring-security 的 authenticationProvider 需要一个 hazelcast 地图
• hazelcast 在启动时从基于 spring-data for mongo 的 mapstore 加载数据
• spring数据要使用ApplicationEventMulticaster
• 还没有。

据我所知，Multicaster 是在调用可配置应用程序上下文的 init() 时创建的，这似乎发生在 spring 安全性之后。 （紧接着……）

我可以强制应用程序上下文提前设置多播器还是稍后设置 hazelcast？

Answer 1

不确定它是 Spring Security 还是一般 Spring 问题，但 Spring Security 类在调用 configurableApplicationContext 上的 init() 之前初始化（所以在创建 ApplicationEventMulticaster 之前）。

我认为这是一个重要问题，因为解决此问题的唯一方法是从我的安全实现中删除依赖注入，并在第一次使用时从应用程序上下文中手动获取所有内容（我现在已经这样做了）。

我可能会为此提出一个 Jira 问题。
