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：

• 我的身份验证弹簧安全性提供程序需要 hazelcast 地图
• Hazelcast在启动时从基于MONGO的Spring数据的Mapstore加载数据
• Spring Data 想要使用 ApplicationEventMulticaster
• 它还没有到那里。

据我所知，Multicaster 是在调用可配置应用程序上下文上的 init（） 时创建的，这似乎是在 Spring 安全之后发生的。（紧接着...

是否可以强制应用程序上下文更早设置多播或稍后设置榛播？

Answer 1

不确定这是 Spring 安全性还是一般的 Spring 问题，但在调用configurableApplicationContext上的 init() 之前（因此在创建ApplicationEventMulticaster之前）初始化了 Spring 安全性类。

我认为这是一个重要的问题，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，并在第一次使用应用程序上下文时手动获取所有内容（我现在已经这样做了）。

我可能会为此提出一个 Jira 问题。
