XML 기반 스프링 빈 정보

Question

안녕하세요 선생님. XML 파일을 생성하고자 하면 다음과 같은 오류가 발생합니다.ㅠㅠ 처음부터 다시 따라하면서 만들었음에도 동일한 에러가 발생하였습니다. 어떤 부분 때문에 에러가 발생하였는지 알 수 있을까요? org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 1 in XML document from class path resource [appConfig.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 292; cvc-elt.1.a: 'beans' 요소의 선언을 찾을 수 없습니다. at

안녕하세요. 소연 님, 공식 서포터즈 OMG입니다. . 강의 메뉴얼에 작성되어 있는 appConfig.xml을 복사하여 확인해보셨을까요? 내용을 복사하여 확인해주세요. 해결이 안될 경우 appConfig.xml 파일 화면을 포함한 인텔리제이 화면을 캡쳐하여 올려주세요 (xml 파일의 패키지 위치를 확인할 수 있게 올려주새요) 추가로 xml을 사용하는 테스트 코드도 같이 올려주시면 확인에 도움이 될 것 같습니다. . 감사합니다.
