从数据库中获取数据存为List类型(存为model)
从数据库中获取的数据，存到一个model中，需要注意两点。
- 一、在dao中，只能用List类型接受结果
- 二、要在mapper中写清楚resultType
//DAO
@Override
public ArrayList<YourModel> getMainInfo(int id) {
// TODO Auto-generated method stub
List<YourModel> result = null;
try{
sqlSession = this.getSqlSession();
}catch (Exception e){
e.printStackTrace();
YourModel yourModel = new YourModel();
try{
result = sqlSession.selectList(this.NAMESPACE.concat("getMainInfo"), yourModel);
}catch (Exception e){
return null;
}
return (ArrayList<YourModel>)result;
}
//mapper
List<model> findByIds(Long... ids);
<select id="findByIds" resultMap="BaseResultMap">
select <include refid="Base_Column_List" /> from model(tableName)
where ID in
<foreach item="item" index="index" collection="array" open="(" separaotr="," close=")">
#{item}
</foreach>
</select>Mybatis存储List类型数据
Dao层
void insertList(List<TZpcjsj> list);*Mapper
<!--批量 插入记录 -->
<insert id="insertList" >
INSERT INTO t_zpcjsj(nian_fen,hang_hao,belong_to_account,zhong_ming,lai_yuan,chang_du,bi_qiang,ma_zhi,ling_zhong,yi_fen,chu_miao_qi,kai_hua_qi,tu_xu_qi,szs_miao_qi,szs_hua_qi,zqd_miao_qi,zqd_hua_qi,shou_huo_zhu_shu,zytx_zhu_xing,zytx_ye_xing,zytx_ling_xing,zytx_zhu_gao,zytx_jie_ling_xing,zytx_ye_xu_xing,ku_wei_bing_zhi,huang_wei_bing_zhi,tian_jian_jue_xuan,mark)VALUES
<foreach collection="list" item="item" index="index" separator=','>
(#{item.nianFen},#{item.hangHao},#{item.belongToAccount},#{item.zhongMing},#{item.laiYuan},#{item.changDu},#{item.biQiang},#{item.maZhi},#{item.lingZhong},#{item.yiFen},#{item.chuMiaoQi},#{item.kaiHuaQi},#{item.tuXuQi},#{item.szsMiaoQi},#{item.szsHuaQi},#{item.zqdMiaoQi},#{item.zqdHuaQi},#{item.shouHuoZhuShu},#{item.zytxZhuXing},#{item.zytxYeXing},#{item.zytxLingXing},#{item.zytxZhuGao},#{item.zytxJieLingXing},#{item.zytxYeXuXing},#{item.kuWeiBingZhi},#{item.huangWeiBingZhi},#{item.tianJianJueXuan},#{item.mark})
</foreach>
</insert>以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
