1. mybatis批量插入數據

?通過list

   <insert id="saveByList" useGeneratedKeys="true" parameterType="java.util.List"> insert into T_App_Default_User(UserID,AppType,CreateTime)values  <foreach collection="list" item="item" index="index" separator="," >  (#{item.userId},#{item.appType},now())  </foreach> </insert>

對應的Mapper文件

public interface AppDefaultUserMapper {void saveByList(List<Map<String, Long>> list);
}

搞定～～～
