[DDV 개발일기] 오라클 DB 연동하기 (메이븐 설정 pom.xml, root-context.xml, servlet-context.xml, mapper 찾기)

💻 오늘의 목표 : 오라클 DB 연동하기

이전에 기본적인 형태의 게시글을 만든 적이 있기 때문에, 금방 끝날 줄 알았다.
그러나 자잘자잘한 오류들로 인해 시간이 꽤 오래 걸렸다..
일단 처음부터 다시 과정을 정리해보자!

🤦‍♂️ 딱밤 쥐어주고 싶은 에러들..

1. ORA-28000: the account is locked

계정이 lock되는 원인
1) DBA(관리자)가 직접 계정에 lock 걸음
2) 계정 접속 시 비밀번호 입력 횟수 제한 초과
3) 비밀번호 유효 기간 만료 (default 3개월)

cmd를 열어서
sqlplus "/as sysdba"를 입력한 다음
alter user {사용자명} account unlock; 을 해주면 된다

2. Mapped Statements collection does not contain value for ~

1) mapper id가 다를경우
- mapper파일(MyBatis의 쿼리문을 등록한 XML파일)에 <select id=''..>에 id와
mapper파일에 직접 접근하는 java파일(DAO나 service)에 적어놓은 id값이 다른 경우

2) Parameter와 bean의 필드명이 틀린 경우

3) mapper파일(MyBatis의 쿼리문을 등록한 XML파일)에 정의된 네임스페이스(namespace)와
mapper파일에 직접 접근하는 java파일(DAO나 service)에서 호출하는 네임스페이스(namespace)가 다를 경우

4) MyBatis config파일에 mapper가 정의가 되어 있지 않거나 Spelling이 틀린 경우

5) mapper에 정의된 namespace 명칭이 같은 Application 내에 중복 될 경우

나는 mapper를 가져오는 과정에서 에러가 발생했다 거의 3-4시간을 찾았다 ...
다른 에러를 고치는 과정에서 root-context.xml 중 classpath:*/ 로 경로를 변경해줬는데 오히려 *를 붙인게 문제였다

<!-- SqlSessionFactory (파일 없으면 404 에러 뜸) -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
     <property name="dataSource" ref="dataSource" />
     <property name="mapperLocations" value="classpath:/mapper/*-sql.xml" />
</bean>

*를 지워주고 서버를 돌리니까 됐다!!!!
mapper 관련해서 확인해보고 싶으면
'root-context.xml', '(dao파일명).java', '(mapper파일명).xml'을 잘 체크해주자!

이건 내가 테스트로 불러온 select 관련 count sql문 결과!
휴.. 이제 얼른 나머지 작업해야지
