Mybatis

ICE4에서 Mybatis를 사용하기위한 기본 가이드

Profile .yml

활성화된 profile 의 application yml 파일에 Mybatis mapper classpath가 설정되어 있어야 한다.

src/main/resources/application-{active profile name}.yml

application-dxp-loc.yml

spring:
  profiles:
    active: dxp-loc

Mybatis mapper classpath 설정

ice-mybatis:
  mapper-locations: classpath:mybatis/*.xml

Datasource

접속하고자 하는 DB연결에 필요한 정보를 .json 으로 작성

src/main/resources/schema/profiles/{active profile name}/datasource.json

Field	Description
typeId	datasource 값 고정
id	datasource ID
ssl	ssl 여부	true / false
dsName	datasource 이름
jdbcUrl	DB url
dbType	DB 유형 Oracle, MySQL, Maria, MS-SQL 지원	CODE oracle mysql maria mssql
username	DB user ID
password	DB user Password

[
  {
    "typeId" : "datasource",
    "id" : "mySqlDb",
    "ssl" : false,
    "dsName" : "Test DB (Maria)",
    "jdbcUrl" : "jdbc:mysql://125.131.88.77:3306/ice2",
    "dbType" : "maria",
    "username" : "ice2",
    "password" : "ice2"
  },
  {
    "typeId" : "datasource",
    "id" : "oracleDb",
    "ssl" : false,
    "dsName" : "Test DB (Oracle)",
    "jdbcUrl" : "jdbc:oracle:thin:@125.131.88.69:8200:ORCL",
    "dbType" : "oracle",
    "username" : "ICE",
    "password" : "ICE1234"
  },
  {
    "typeId" : "datasource",
    "id" : "msDb",
    "ssl" : false,
    "dsName" : "Test DB (MS)",
    "jdbcUrl" : "jdbc:sqlserver://125.131.88.94:1500;databaseName=IPS",
    "dbType" : "msSql",
    "username" : "icafe13",
    "password" : "icafe1234!@"
  }
]

Mapper Interface

Mapper 설정 파일(xml)에 있는 SQL 쿼리문을 호출하기 위한 인터페이스
@Mapper annotation 사용
SQL id는 인터페이스에 정의된 메서드명과 동일하게 작성
SQL returnType은 인터페이스의 리턴 타입과 동일하게 작성

src/main/java/net/ion/ice/services/mybatis/mapper/

/src/main/java/net/ion/ice/services/mybatis/mapper/SampleLogicMybatis.java

@Mapper
public interface SampleLogicMybatis {
    public List<Map> list();
}

Mapper XML

MyBatis Mapper XML 파일은 실행할 SQL문을 정의해놓은 파일

src/main/resources/mybatis/

namespace에 인터페이스의 전체 경로를 기입

<mapper namespace="net.ion.ice.services.mybatis.mapper.SampleLogicMybatis">

resultType, parameterType : full package + class 명칭을 명시

resultType="org.springframework.util.LinkedCaseInsensitiveMap"

[ 참조 : https://mybatis.org/mybatis-3/ko/sqlmap-xml.html ]

src/main/resources/mybatis/sampleLogicMybatis.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="net.ion.ice.services.mybatis.mapper.SampleLogicMybatis">
    <select id="list" resultType="org.springframework.util.LinkedCaseInsensitiveMap">
        select a.NID as id
        , a.CONTENTS_TITLE as title
        , a.RELEASE_DATE as releaseDate
        , a.CONTENTS_SYNOPSIS as contents
        , a.BASE_PRICE as price
        , b.SERIES_ID as seriesId
        , b.TITLE as seriesTitle
        from MOVIE a, MOVIE_SERIES b
        where a.SERIES_ID = b.SERIES_ID
        <if test="id != null">
            and a.NID = #{id}
        </if>
    </select>
</mapper>

Service

mybatisService.getSqlSessionTemplate("oracleDb")

src/main/java/net/ion/ice/services/

[참조 : https://mybatis.org/spring/ko/sqlsession.html#SqlSessionTemplate ]

mybatisService.getSqlSessionTemplate("datasource id")

@Autowired
private MybatisService mybatisService;
