Apache POI 数据透视表 - 如何在 Java 中使用“In-Between”值过滤器

Question

我正在尝试使用 Apache POI 设计一个数据透视表，我想要做的是最初打印大于某个数字以及小于某个数字的总和值。 但是，当我尝试这样做时，过滤器会相互抵消，这意味着打印出不应该存在的总和值。 例如，如果我希望总和介于 2 和 5 之间，则总和值 1 以及大于 5 的数字都会被打印出来。 这是解释我的问题的代码：

这是由于运行此代码而打印的数据透视表：

那么，如何获取需要为*.xlsx文件设置的内容？ *.xlsx只是一个ZIP档案。 因此，可以解压缩*.xlsx并查看其中的内容。

因此，使用Excel的GUI执行您需要的操作，保存*.xlsx ，然后解压缩它并查看/xl/pivotTables/pivotTable1.xml 。 在那里您将找到以下过滤器设置：

<filters count="1">
 <filter fld="1" type="valueBetween" evalOrder="-1" id="1" iMeasureFld="0">
  <autoFilter ref="A1">
   <filterColumn colId="0">
    <customFilters and="1">
     <customFilter operator="greaterThanOrEqual" val="2"/>
     <customFilter operator="lessThanOrEqual" val="5"/>
    </customFilters>
   </filterColumn>
  </autoFilter>
 </filter>
</filters>

所以customFilters需要设置以下过滤器是AND链接的。 这是您的代码尚未设置的内容。
