Springboot 2.5.x 버전은 spring-cloud-starter-vault-config 2.2.X 버전과 현재(2021.08.12)는 되지 않는다.
이런 오류가 난다.

대충 보면 ConfigurationBeanFactoryMetadata class를 못찾는다는 뜻이다.
이유는 Springboot와 Springcloud의 Release Train이 다르기 때문에 아직 의존성이 깔끔하게 해결되지 않아서다.

Adding Spring Cloud To An Existing Spring Boot Application
If you an existing Spring Boot app you want to add Spring Cloud to that app, the first step is to determine the version of Spring Cloud you should use. The version you use in your app will depend on the version of Spring Boot you are using.
The table below outlines which version of Spring Cloud maps to which version of Spring Boot.
| Spring Cloud Dalston, Edgware, Finchley, and Greenwich have all reached end of life status and are no longer supported. |
해서 이 둘을 연결하려면 gradle 설정이 좀 필요하다.
gradle 설정은 대충 다음처럼 하면 된다. (참고로 아래코드는 kotlin dsl을 이용했따)
ext {
set("springCloudVersion", "2020.0.3")
}configure<io.spring.gradle.dependencymanagement.dsl.DependencyManagementExtension> {
imports(delegateClosureOf<io.spring.gradle.dependencymanagement.dsl.ImportsHandler> {
mavenBom("org.springframework.cloud:spring-cloud-dependencies:2020.0.3")
})
}
그리고 한가지 더
원래 vault config는 bootstrap.yml을 읽어서 vault config를 하게 되었는데
springcloud bootstrap 2020.X 버전 부터는 기본적인 application.yml 안에서 vault 설정을 읽게 바뀌었다.
