bean未初始化成功，首先需要檢查bean。

若bean注入沒有問題，本地跑也沒有問題，可以嘗試手動將該類加載到上下文中，避免自動注入時，類加載順序異常導(dǎo)致的bean加載失敗。

1、實(shí)現(xiàn)這個類

ApplicationContextAware

2、注入上下文

private lateinit var ctx: ApplicationContext
override fun setApplicationContext(applicationContext: ApplicationContext) {this.ctx = applicationContext
}

3、拿到bean

val c = ctx.getBean(CredentialGenerator::class.java)
