Я пытаюсь связать результат запроса (внутри класса @Mapper и используя аннотацию @Select для запроса) с Mapper. xml, поскольку у меня есть довольно сложный POJO для сопоставления.
Вот мой код:
MapMapper.class:
@Mapper
public interface MapMapper {
@Select("select seat_id,row_pos,column_pos,is_assigned,team_id,map_id from t002_seat_mst where map_id=#{mapId}")
@ResultMap("SeatsResultMap")
MapDTO fetchMapSeatsByIdWhenNoTeam(int mapId);
}
SeatsMapper. 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="com.seat.arrangement.dao.mapper.MapMapper">
<resultMap id="SeatsResultMap" type="com.seat.arrangement.model.MapDTO">
<result column="map_id" jdbcType="NUMERIC" property="mapId" />
<collection property="seats" ofType="com.seat.arrangement.model.SeatDTO">
<result property="seatId" column="seat_id" />
<result property="rowNumber" column="row_pos" />
<result property="columnNumber" column="column_pos" />
<result property="isAssigned" column="is_assigned" />
<result property="team.teamId" column="team_id" />
</collection>
</resultMap>
</mapper>

У меня есть mybatis-config.xml файл внутри resources/config/mybatis-config.xml
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'>
<!--<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Confi 3.0//EN"
"config//mybatis-3-config.dtd">-->
<configuration>
<mappers>
<mapper resource='config/SeatsMapper.xml'/>
</mappers>
</configuration>
Поскольку я предоставляю свойства jdb c из файла application.properties, я использовал только <mappers></mappers> в mybatis-config.xml. Это неправильно?
Вот мой файл application.properties:
server.port=7777
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.testWhileIdle=true
spring.datasource.validationQuery=SELECT 1
mybatis.config=classpath:config//mybatis-config.xml
Кто-нибудь может мне помочь, если я ошибаюсь? Спасибо.
