다음과 같이 maven 에 추가 한다. 혹시 3.2.0 버전 사용시 -> 3.1.0 낮춰서 테스트 해보면 됨.

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-resources-plugin</artifactId>
	<version>3.1.0</version>
</plugin>

 - slf4j는 자바 로깅 시스템을 쉽게 사용할 수 있도록 해주는 라이브러리입니다.

 - 다양한 자바 로깅 시스템을 사용할 수 있도록 추상화를 통해 로깅 기능을 제공합니다. 

# slf4j를 사용함으로서 얻을 수 있는 이점

 - 기존에 사용하는 로깅 시스템을 교체하고 싶을 때, 소스 코드를 수정하지 않고도 maven이나 gradle의 의존성 설정만 바꾸면 손쉽게  적 

   용할  수 있습니다.

• none: No change to the database structure. (실서버 운영시 기본값)
• update: Hibernate changes the database according to the given Entity structures. - 변경된 스키마만 적용한다.
• validate: 변경된 스키마가 있는지 확인만 한다. 만약 변경이 있다면 Application을 종료한다.
• create: Creates the database every time, but don’t drop it when close. - 시작될 때만 drop하고 다시 생성한다.
• create-drop: Creates the database then drops it when the SessionFactory closes. - 시작과 종료에서 모두 drop한다.

데이터베이스 테이블에 컬럼이 생성되지 않는 필드 경우 사용합니다. 

ex)  - 게시판의 comment count 구할 떄

#hibernate가 키생성방식을 결정

@GeneratedValue(stategy=GenerationType.AUTO)

# 사용하는 databases 가 키생성방식을 결정

@GeneratedValue(stategy=GenerationType.IDENTITY)

 - oracle -> 별도의 번호를 위한 table 생성

 - mysql or mariadb -> Auto Incremnet default

#SECUENCE(@SequenceGenerator)

 - database의 sequence기능을 사용 

 - oracle -> sequence

 - mariadb -> 10.3 부터 sequence 지원

#TABLE (@TableGenerator)

 - 키 전용 Table별도생성

<html xmlns:th="http://www.thymeleaf.org"
      xmlns:sec="http://www.thymeleaf.org/extras/spring-security">

위 처럼 html 을 선언하거나 layout을 사용했다면 아래와 같이 선언 합니다.

<html xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout" layout:decorate="~{thymeleaf/layout/default}" xmlns:sec="http://www.thymeleaf.org/extras/spring-security">

ex) ROLE_ADMIN 권한을 가진 사용자에게만 보여준다면 아래와 같이 사용 할 수 있습니다.

<div class="card-body" sec:authorize="hasRole('ROLE_ADMIN')" ></div>

 <td th:switch="${#strings.toString(item.rdStatus)}" >
   <span th:case="대기"  th:text="${item.rdStatus}" class="badge badge-outline-primary"  />
   <span th:case="할당"  th:text="${item.rdStatus}" class="badge badge-outline-primary"  />
   <span th:case="진행"  th:text="${item.rdStatus}" class="badge badge-outline-primary"  />
   <span th:case="완료"  th:text="${item.rdStatus}" class="badge badge-outline-primary"  />
   <span th:case="취소"  th:text="${item.rdStatus}" class="badge badge-outline-primary"  />
 </td>

switch 문에서 ${#strings.toString(item.rdStatus)} 와 같이 enum 값을 -> toString 처리 object->string변환

을 통해서 switch, case문 정상 동작 됩니다.

ClassLoader classLoader = getClass().getClassLoader();
try (InputStream inputStream  = classLoader.getResourceAsStream(filePath))
{
	InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
}catch(Exception e){
	e.printStackTrace();
