ICE4에서 Mybatis를 사용하기위한 기본 가이드
...
Application yml
활성화된 profile 의 application yml 파일에 Mybatis mapper classpath가 설정되어 있어야 한다.

datasource에 작성한 DB 접속정보의 id 로 SqlSessionTemplate 생성
mybatisService.getSqlSessionTemplate("oracleDb")
SqlSessionTemplate으로 Mapper Interface를 통해 Mapper xml 쿼리 실행
getSessionTemplate().selectList("net.ion.ice.services.mybatis.mapper.SampleLogicMybatis.list")
[참조 : https://mybatis.org/spring/ko/sqlsession.html#SqlSessionTemplate ]mybatisService.getSqlSessionTemplate("datasource id")

LogicRepository
...
"NodeType의 repositoryType": "logic"
"serviceName": "sampleLogicMybatisService"
...
logic 유형으로 Mybatis로 SQL 실행 및 반환된 결과를 사용하는데 활용할 수 있다.
serviceName(LogicRepository를 implement하는 서비스명)을 설정
기본적인 CRUD 및 List API 호출시에 해당 서비스를 호출하여 처리된 결과 반환
