SPRINGBOOT HTTPS 적용 중 에러

Question

안녕하세요. 강의를 보면서 SSL 적용중 에러가 있어서 문의드립니다. 위와 같이 keystore를 등록 후 위 사진과 같이 properties를 설정하여 https를 적용 시키려고하는데  Failed to start bean 'webServerStartStop' 이라는 에러가 발생하면서 실행이 되지않습니다. 구글링을 해보고 있는데 별다른 해결책이안보여서 혹시 제가 놓친 부분이 있는건지.. 아니면 무언가를 추가해야하는건지 궁금합니다.. 로그상를 봤을때는 password가 incorrect라고 나오는데 keytool -v -list -keystore ..로 확인시 해당 패스워드로 확인이 되었습니다. jdk 1.8을 사용중에 있습니다. --- CONSOLE LOG --- error starting ApplicationContext.

해결 하였습니다. server.ssl.key-store-password = 123456 properties에 위코드 입력시 정상 적용됩니다.
