这里没有更新，实际上是： org.springframework.boot.EnvironmentPostProcessor，现在启动就会报错：

spring.factories 是 Spring Boot 2.X 的方式，在 Spring Boot 3 中只能算作兼容或者过时的方式。

spring.factories 文件存在的价值，一方面是通用组件为了兼容 Spring Boot 2.X，另一方面就是为了支持 Bootstrap 模式。

但是 Spring Cloud Alibaba 自 2023.0.1.3 版本之后已经不推荐 Spring Cloud Bootstrap 方式， 社区后续也会考虑删除。而且 Spring Cloud 2025.1.0，基于 Spring Boot 4.X 与 Spring Boot 3.X 都无法兼容，就更本没有必要考虑与 Spring Boot 2.X 兼容的问题了。所以可以完全不需要 spring.factories 文件了。

因此，个人觉得 spring.factories 文件可以在删除 Bootstrap 方式 的同时同步删掉。其实 Spring Cloud Alibaba 2025.1.0.0 就可以做这个事情。
