1. mybatis批量插入数据

通过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>
    

对应的Mapper文件

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

搞定～～～
