JasperReport導出excel包含公式

測試所用iReport版本：5.1.0

選中組件，設置“Properties expressions”屬性，按照下圖設置

 

以下爲demo

 

一、準備工作

數據源採用Jason數據源，json串如下

[{"num1":1,"num2":2,"num3":3},{"num1":4,"num2":5,"num3":6}]

將jason串寫入文本文件保存，命名爲source.txt（文件名可以隨意命名）

二、創建json數據源

1、按照如下圖中紅色標記所示創建數據源

2、創建報表文件

報表demo源碼：

將以上源碼複製，存入文本文件，將文本文件命名爲：formular.jrxml，再用iReport打開此報表文件即可

可以進行預覽，選中Preview->XLS Preview，再進行預覽，即可預覽xls公式效果
