안녕하세요, 인프런 AI 인턴입니다. 해당 문제는 DataSource 구성에서 적절한 드라이버 클래스를 결정하지 못해 발생하는 문제로 보입니다. 스프링 부트는 spring.datasource.url 속성을 통해 데이터베이스 URL을 지정해야 합니다. 이 속성이 설정되지 않고, 경로에 내장 데이터베이스(H2, HSQL, Derby 등)에 대한 의존성도 포함되지 않은 경우 위와 같은 오류가 발생할 수 있습니다. 해결 방법으로는 다음과 같은 절차를 따라보시기 바랍니다: application.properties 혹은 application.yml 파일에 데이터베이스 연결에 필요한 spring.datasource.url , spring.datasource.username , spring.datasource.password 등의 속성이 올바르게 설정되어 있는지 확인하세요. 예시: spring.datasource.url=jdbc:mysql://localhost/test spring.datasource.username=dbuser spring.datasource.password=dbpass 사용하고 있는 데이터베이스에 맞는 JDBC 드라이버가 의존성으로 포함되어 있는지 확인하세요. 예를 들어, MySQL을 사용하는 경우 pom.xml 파일에 아래와 같은 의존성이 포함되어 있는지 확인합니다. mysql mysql-connector-java runtime 만약 내장 데이터베이스를 사용하고자 한다면, 해당 내장 데이터베이스에 대한 의존성을 pom.xml 파일에 추가해야 합니다. 예를 들어, H2 데이터베이스를 사용하려면: com.h2database h2 runtime 적절한 JDBC 드라이버 클래스를 명시적으로 지정해야 하는 경우, spring.datasource.driver-class-name 속성을 사용하여 지정할 수 있습니다. 만약 여전히 문제가 해결되지 않는다면, 추가적으로 데이터베이스 연결과 관련된 설정을 점검해보시기 바랍니다. 원문 정보 및 추가적인 도움을 위해 Spring Boot 공식 문서를 참고할 수 있습니다: DataSource Configuration
