갑자기 멀쩡하던 스프링 프로젝트가 구동이 안됩니다.

Question

https://okky.kr/questions/1405717스프링 부트 자체 웹서버를 구동하려고 하면 이것과 유사하게 오류가 뜹니다. 해당 링크의 답변에 나오는 것처럼 버전도 맞췄음에도 불구하고 계속해서 오류가 뜨네요. 무엇보다 명령어를 하나 추가하기 전까지만 해도 잘되던 것이 안됩니다. 명령어를 지운 후에도 똑같구요. 혹시 이유를 알려주실 수 있으신 분 계신가요? 아니면 추론도 좋습니다 ㅠ오류내용 및 코드입니다.오류내용org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'myController': Unsatisfied dependency expressed through field 'boardDao';nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'interfaceBoardDao' defined in file [C:\User\qawsz.HOWDOIKNOW.000\Documents\workspace-spring-tool-suite-4-4.13.0.RELEASE\PostBoard\bin\main\com est\spring\dao\InterfaceBoardDao.class]: Unsatisfied dependency expressed through bean property 'sqlSessionFactory';nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [org/mybatis/spring/boot/autoconfigure/MybatisAutoConfiguration.class]: Unsatisfied dependency expressed through method 'sqlSessionFactory' parameter 0;nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed;

이럴때는 프로젝트 clean 하고 재기동하느것도 방법입니다
