스코프와 Provider 강의에서 질문합니다.

안녕하세요. 선생님 영상을 보면서 라이브 코딩하면서 오류가 발생할때 저는 오류가 발생을 안하고

오류가 발생하면 안되는 곳에서는 발생해서 질문남깁니다.

package web;

import hello.core.common.MyLogger;

    private final LogDemoService logDemoService;
    private final ObjectProvider<MyLogger> myLoggerProvider;

    @RequestMapping("log-demo")
    @ResponseBody
    public String logDemo(HttpServletRequest request) {

        String requestURL = request.getRequestURL().toString();
        MyLogger myLogger = myLoggerProvider.getObject();
        myLogger.setRequestURL(requestURL);

        myLogger.log("controller test");
        logDemoService.logic("testId");
        return "OK";
    }
}

영상초반에 Provider 적용후 강의에서는 local 사이트 화면에서는 OK로 변경된 화면이 나오지만

저의 사이트에서는 여전히 오류가 발생하고 있어서 문의드립니다.

추가로 인텔리제이 종료후 재시작해서 CoreApplication를 작동해보았는데 추가적인 오류가 나왔습니다.
