}

以以下错误结束

待覆盖的Vault-Value其他：待覆盖的Vault-Value已成功连接到数据库

在上下文初始化期间-取消刷新尝试：org.springframework.beans.factory.BeanCreationException：创建名为“demo application”的bean时出错：调用init方法失败；嵌套异常为java.lang.IllegalArgumentException：Username to-be-overwriter-by-Vault-Value 2019-05-30 15:31:39.178错误18680----[main]O.S.Boot.SpringApplication

当我将vault与文件系统集成时，时间路径类似于secret\key，它可以很好地处理这个新的更改，它停止工作。

Answer 1

但是，这个例外实际上似乎与vault无关。上面写着

java.lang.IllegalArgumentException: Username to-be-overwritten-by-vault-value

是否在属性文件中定义的默认值中有空格？
