我想从保管库中检索一些秘密（数据库用户名/密码）并使用 spring.data.mongodb 配置 MongoDB。

我在 spring-boot-starter-data-mongodb 应用程序中完成了保险库集成。

硬编码值工作正常，尝试使用${vault.application-name.property_name}

这是我在 application.yml 中提供的配置：

spring:
  data:
    mongodb: 
      host: 10.xx.xxx.xxx
      port: 27017
      database: ${vault.application-name.database-name}
      username: ${vault.application-name.database-username}
      password: ${vault.application-name.database-password}
      authentication-database: ${vault.application-name.authentication-database}

考虑到上述配置是否正确，我应该从 Vault 接收这些属性，但目前，应用程序在执行时抛出以下异常：

与Spring Cloud Vault集成时，理想情况下，唯一需要提供的是role名称。除了 Spring Cloud Vault 与 Spring Boot 之外，我不会建议任何其他集成方法，因为您需要在 Spring Boot 初始化 MongoDB 配置之前获取属性，这可能会变得非常棘手。

请参阅文档以获取更多参考，这里是带有 Spring Cloud Vault示例的MySQL的链接。
