Request 정보 처리를 위한 설정


사용자가 공지사항 등록화면에서 입력한 정보와 첨부파일 정보를 저장할 테이블을 생성하고 DB연동을 위한 Datasource 설정, Mybatis연동 설정, Transaction설정, 파일처리를 위한 multipartResolver 설정을 차례대로 설명하겠습니다.


1. Database 테이블 생성

2. Datasource 및 Transaction 설정

 - root-context.xml 파일을 참조하여 네임스페이스와 설정 정보를 추가합니다.

 - oracle Driver를 찾지 못하는 error가 발생하면, 오라클 설치 폴더에서 ojdbc를 찾아 JAVA를 설치한 곳으로 복사하면 error가 해결됩니다.

=> 오라클홈 -> jdbc -> lib -> ojdbc6.jar 파일을

=> 자바설치폴더 -> jre -> lib -> ext 폴더로 복사
