- 新建一个mapper的package来管理mapper(有mapper接口及对应的xml文件)
在此包下我写了一个BookMapper的接口(同时对应一个BookMapper.xml文件)
package com.qfedu.ssm.mapper;
import java.util.List;
import com.qfedu.ssm.entity.Book;
public interface BookMapper {
public List<Book> findByTypeId(int typeId);
}
<?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.qfedu.ssm.mapper.BookMapper">
<resultMap type="Book" id="BookResultMap"/>
<select id="findByTypeId" parameterType="int" resultMap="BookResultMap">
select * from tb_book where typeid=#{typeId}
</select>
</mapper>
