与在Java中使用Apache POI读取Excel有关的问题
[英]Issue related to Reading Excel using Apache POI in java
问题描述
I am trying to create an excel file of 2007. Scenario for Creation of Excel from other file. 
我正在尝试创建2007年的excel文件。从其他文件创建Excel的方案。
Input file :- InputFile.xlsx with One Sheet 输入文件：-具有一张纸的InputFile.xlsx
Calculation File :- Model.xlsx with four sheets 计算文件：-具有四张纸的Model.xlsx
Description for Calculation file :- 1) First Sheet is input file 2) Second sheet is Output 3) Third and Fourth Sheet is calculation sheets. 计算文件说明：-1）第一张纸是输入文件2）第二张纸是输出文件3）第三张和第四张纸是计算纸。
in Java using Apache POI I am reading Excel file. Java中使用Apache POI读取Excel文件。 in one function I am reading file,takes input files InputFiles.xlsx 在一个功能中，我正在读取文件，接受输入文件InputFiles.xlsx
in second function I am merging two sheets in model.xlsx file. 在第二个功能中，我要合并model.xlsx文件中的两张纸。 iein the first sheet of Model.xlsx merging first sheet of InputFile.xlsx 即后面板的第一片Model.xlsx合并的第一片InputFile.xlsx
In third function I am reading output, that affect after writing in model.xlsx and reading it. 在第三个函数中，我正在读取输出，该输出在写入model.xlsx并读取后会产生影响。

Problem is :- While reading second sheet using apache poi in java, it read previous data not the updated data after calculation.even if Model.xlsx contain updated data java reads only previous data.This is very strange find me any solution. 问题是：-在Java中使用apache poi读取第二张纸时，它在计算后读取的是先前的数据而不是更新的数据。即使Model.xlsx包含更新的数据，java也只能读取先前的数据。这很奇怪，我找不到任何解决方案。
Kindly please assist me. 请帮助我。
Thanks. 谢谢。
