Mapper 파일을 만들고 이 파일을 지정하는 경우 사용할 수 있다.
만약 Mapper 인터페이스를 구현하는 방법을 사용할 경우
<mybatis:scan base-package="com.example.domain.mapper" /> 을 작성하여 Mapper 인터페이스의 스캔을 활성화해주어야 한다.
db.properties 생성
▶ src/main/resource/properties/db.properties
db.driver=com.mysql.jdbc.Driver #mysql
db.url=jdbc:mysql://localhost:3306/db명
db.username=username
db.password=password
mapper.xml 추가
mybatisMapper/**/*.xml
→ mybatisMapper 디렉터리 하위 디렉터리들 중에 .xml로 끝나는 파일들을 지정
*.xml: .xml로 끝나는 파일들
**: mybatisMapper 디렉터리 하위 디렉터리들
▶src/main/resource/mybatisMappers/board.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.spring.boardapp.dao.BoardDao">
<select id="getB" parameterType="java.util.HashMap" resultType="com.spring.boardapp.domain.Board">
SELECT id,
subject,
content,
writer,
date_format(regist_datetime, '%Y-%m-%d %H:%i:%s') regist_datetime
FROM board
WHERE id = #{id}
</select>
...
</mapper>- parameterType
파라미터를 어떤 타입으로 전달 받을지 지정, 해당 코드에서는 id를 java.util.HashMap 타입으로 전달받겠다는 뜻이다. - resultType
반환 값을 어떠한 타입으로 저장할지. 해당 코드에서는 Board 객체에 담긴다.
mybatis-config.xml: MyBatis 설정
▶src/main/resource/mybatis-config.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 별칭 지정 -->
<typeAliases>
<typeAlias type="com.spring.boardapp.domain.Board" alias="Board"/>
</typeAliases>
</configuration><configuration> 태그 사이에 MyBatis 설정을 해주면 된다.
설정 중 하나의 예를 들자면 별칭이 있다. 자주 사용하는 타입의 별칭을 지정할 수 있다.
▶src/main/resource/mybatisMappers/board.xml
board.xml 코드의 일부인데 resultType을 보면 알 수 있듯이 별칭을 사용하여 패키지 명을 지정이 간단해졌다.
<mapper namespace="com.spring.boardapp.dao.BoardDao">
<select id="getB" parameterType="java.util.HashMap" resultType="Board">
...
</select>
...
</mapper>
