一,最终实现:查询条件及查询结果如下图所示
需要实现:分组,求和,聚合后排序,总计,分页
二, 需求分析:关于分组维度
es数据主键为:日期(年月日)+采购组织+采购组+门店
统计维度:可根据是否选择门店,按日或按月统计可分为四种情况
日+采购组织+采购组;采购组织+采购组;日+采购组织+采购组+门店;月+采购组织+采购组+门店;
按正常es多条件分组求和处理方式很麻烦,可参考网上写法。可以转变思路,把每个维度拼接成一个字段,即新增四个字段,多条件分组统计转化为单条件分组统计,实现起来会简单的多。如下图所示:
三,代码实现
关于聚合
难点在于聚合统计,及聚合统计后再合计
关于排序
聚合求和的字段排序与不需要聚合求和的字段区分开来,前者可以直接应用es特性直接排序,后者排序,对处理之后的数据lis排序,java特性排序对list排序
关于分页
es无法复杂聚合后排序,对处理之后的数据进行伪分页排序,并不是真正意义上的排序,可以减轻前端压力,对于后台是对所有的数据伪分页。

聚合求和及聚合合计字段处理
1.注意维度下数据量,如果大于10000条,多余的数据不会计入聚合统计,如下图说明
2.注意聚合求和和聚合合计的层级关系,聚合统计字段以子聚合关联,聚合合计字段与分组维度一个层级
/**
* 统计,排序
* 分组size含义:需要返回分组后的个数;如按某维度分组,10个结果,size=2,只会返回两个结果。应该小于10000
* 分组size测试:
* 条件:全部100家门店,日期5月份,包含门店,按日维度统计
* 结果:查询总量:19703 1,size>10000,程序异常;2,size=10000(查询时长大概30s),实际只取前10000条数据聚合返回,导致数据不准
* 处理:如果size>10000,抛业务异常,缩小范围
