감사합니다. 제가 급히 하느라 교재를 복사했더니 이런 문제가 생겼습니다.^^ 정상적으로 테이블 생성 SQL이 로그에 확인이되고마찬가지고 테이블이 생성되는것을 확인하였습니다.감사합니다.주말에 몰아서 또 강의를 듣도록 하겠습니다.

프로젝트 기동로그 확인문의입니다.

강사님..인텔리제이로 apiserver 관련 프로젝트구성하고 Todo entity 클래스까지 구성하여구동을 해보았는데, 아까 말씀드린 출력 로그와또한 ddl 생생관련한 로그확인이 불가능합니다.확인을 부탁드립니다.-- 기본적으로 설정에 필요한 부분은 강의대로<a target="_blank" rel="noopener noreferrer nofollow" href="https://start.spring.io/">spring initializr를 통해서 프로젝트와</a>dependency를 설치했습니다.-- application.properties<pre><code>spring.application.name=apiserver

저도 Header에 momo 메소드를 적용하여 콘솔에 출력하면1회만 실행되는 부분은 확인하였습니다.<pre><code class="language-javascriptreact">import "./Header.css";
import { memo } from "react";

const Header = () => {
 console.log("Header 호출중....")
 return (
 <div className="Header">
 <h3>오늘은 📆</h3>
 <h1>{new Date().toDateString()}</h1>
 </div>
 );
};

const memoizedHeader = memo(Header)
export default memoizedHeader;</code></pre>위에 질문자님처럼 개발자 도구에서 하단의 체크박스on/off시에 헤더 역시 계속 깜박거림이 발생되고 있습니다.&nbsp;console.log에서는 딱 1회만 렌더링 되는데개발자 도구에서 하단의 체크박스 온오프시에 계속전체가 깜박이는 이유를 잘 모르겠습니다.&nbsp;제가 개발자 도구를 잘 못보는 것인지 useCallback부분도 적용후에 개발자 도구를 통하여확인하기 다소 어려운 부분이 있어혹시 Tool을 보는 방법에 제가 오해가 있을까요?

onChange 이벤트 발생시에 이벤트 핸들러에서 입력 또는선택된 값을 e.target.value로 가져는것으로 console.log에서 확인해보았습니다.(input type=text/date, textarea)<img src="https://cdn.inflearn.com/public/files/posts/bc783baa-e7b9-43dc-baa8-6b039dc4e06e/9bbf2a4b-c35e-4f84-a84c-6ce84623bbfa.png" media-type="img" alt="image.png" title="image.png" width="233" height="53">&nbsp;국적같은 select박스에서 e.target을 보면 아래와 같이 출력됩니다. <img src="https://cdn.inflearn.com/public/files/posts/873c9aaa-3c65-4d12-ba38-f4895612166f/414796ef-a3b7-4d81-a5f6-a9cffce52c4e.png" media-type="img" alt="image.png" title="image.png" width="396" height="108">실제 select에서 선택된 값은 어디서 확인할 수 있을까요?&nbsp;
