안녕하세요. 배영현 님, 공식 서포터즈 OMG입니다. 2021-08-25 23:04:29.036 ERROR 9076 --- [nio-8080-exec-8] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.thymeleaf.exceptions.TemplateInputException: Error resolving template [ members/memberList ], template might not exist or might not be accessible by any of the configured Template Resolvers] with root cause org.thymeleaf.exceptions.TemplateInputException: Error resolving template [ members/memberList] , template might not exist or might not be accessible by any of the configured Template Resolvers 하이라이트 표시한 부분과 관련있어 보입니다. 위의 코드에서 아래와 같이 /를 포함하고 있는지 확인부탁드립니다. return " / members/memberList"; 위의 강의교안과 동일하게 되어 있다면 members/memberList.html 파일의 경로가 맞는지, @GetMapping("경로")도 확인부탁드립니다. 감사합니다.
