근 3시간동안 다른 분들 비슷한 에러 메시지의 질문을 확인해봤는데 도저히 해결이 안되어 남깁니다..

에러 메시지는 다음과 같습니다.

spring: #띄어쓰기 없음
  datasource: #띄어쓰기 2칸
    url: jdbc:h2:tcp://localhost/~/jpashop #4칸
    username: sa

띄어쓰기는 다 수정해봤고, 오타도 봤는데 잘 모르겠습니다..

H2는 켜져있고,

build.gradle은

plugins {
   id 'org.springframework.boot' version '2.4.1'
   id 'io.spring.dependency-management' version '1.0.10.RELEASE'
   id 'java'
}
group = 'jpabook'

sourceCompatibility = '11'

   compileOnly {
      extendsFrom annotationProcessor
   }
}
repositories {
   mavenCentral()
}
dependencies {
   implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
   implementation 'org.springframework.boot:spring-boot-starter-validation'
   implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'

   testImplementation 'org.springframework.boot:spring-boot-starter-test'
//JUnit4 추가
   testImplementation("org.junit.vintage:junit-vintage-engine") {
      exclude group: "org.hamcrest", module: "hamcrest-core"
   }
}
test {
   useJUnitPlatform()
}

위와 같습니다.
도움 주시면 감사하겠습니다.

답변 감사합니다
해결되었습니다.

EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})

이 코드가 문제가 되었던 이유는
특정 자동설정 클래스를 비활성화 하는 exclude={DataSourceAutoConfiguration.class} 코드가 

ApplicationContext를 구성하는데 방해했다고 이해하면 될까요?

 

OMG님의 프로필 이미지
OMG

데이터소스 설정 클래스를 자동설정에서 제외시켜서 발생한 문제로 보시면 됩니다

프로젝트코드 확인해보았습니다.

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})

어노테이션 선언을 제거해주세요.

yml 은 이렇습니다

OMG님의 프로필 이미지
OMG

yml 상에서는 크게 문제점이 보이진 않는 것 같습니다.

직접 코드를 확인해봐야 할 거 같아요,

전체 프로젝트를 압축해서 구글 드라이브로 공유해서 링크를 남겨주세요.

구글 드라이브 업로드 방법은 다음을 참고해주세요.

https://bit.ly/3fX6ygx

주의: 업로드시 권한 문제 꼭 확인해주세요

감사합니다

안녕하세요. ch93514님, 공식 서포터즈 OMG입니다.

yml은 띄어쓰기에 유의해야합니다.

url, username과 passowrd,driver-class-name의 띄어쓰기가 다른 것으로 보이네요.

제공해드리는 프로젝트 yml을 복사 붙여넣기 하여 확인해주세요


감사합니다.

제공해주신 yml을 복사 붙여넣기 해봤지만 같은 에러가 뜹니다..
