• 新建一個(gè)mapper的package來管理mapper(有mapper接口及對(duì)應(yīng)的xml文件)
  在此包下我寫了一個(gè)BookMapper的接口(同時(shí)對(duì)應(yīng)一個(gè)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>
