4. 설명

• 기존에 DB연결을 dataSource를 이용했으나 log4j-remix를 쿼리의 중간을 가로채 정렬하고 쿼리를 출력하는 역할을 합니다.
  
• 기존에 사용한 DB연결은 dataSourceSpied로 변경하고, 새로 dataSource를 만들고 로그타입과 쿼리를 어떻게 출력하지 설정함
• log4j에서 jdbc.sqlonly로거를 이용하여 쿼리를 출력하도록 하고 dataSourceSpied(log4j-remix)가 쿼리를 정렬함
• log4j설정에 추가한 jdbc.resultsettable가 쿼리결과를 출력하도록 합니다.(이부분을 생략하면 쿼리결과 출력은 없어짐)
