一、介绍 当前B/S模式已成为应用开发的主流，而在企业办公系统中，常常有客户这样子要求：你要把我们的报表直接用Excel打开(电信系统、银行系统)。或者是：我们已经习惯用Excel打印。这样在我们实际的开发中，很多时候需要实现导入、导出Excel的应用。 目前，比较常用的实现Java导入、导出Excel的技术有两种Jakarta POI和Java Excel 下面我就分别讲解一下如何使用这两个技术实现导入、导出Excel 二、使用Jakarta POI导入、导出Excel Jakarta POI 是一套用于访问微软格式文档的Java API。Jakarta POI有很多组件组成，其中有用于操作Excel格式文件的HSSF和用于操作Word的HWPF，在各种组件中目前只有用于操作Excel的HSSF相对成熟。官方主页 http://poi.apache.org/index.html ，API文档 http://poi.apache.org/apidocs/index.html 2.1 环境配置 2.1.1下载jar 官方下载： http://poi.apache.org/download.html 这里可以下载到它的最新版本和文档，目前最新版本是3.7，这里使用比较稳定的3.6版。 2.1.2加入jar包 将根目录下的poi-3.6-20091214.jar和Lib目录下三个通用包

Writing Multiple CSV Files From Excel using Java and Jexcelapi

由 我与影子孤独终老i 提交于 2019-12-25 05:18:08
问题 I'm trying to create a program that writes all the data from excel to multiple csv files. Currently, my program creates n number of files, and only the last row of excel is being written on the last csv file. Programming Background Observation: It seems like the file is writing. But for each written row, it somehow creates the same file 250 times. It erases the row that was written last. I may have some problems using the OutputStream or BufferedWriter . I just can't figure out what it is.

Why does jExcelAPI dump warnings in stderr and how to stop this behaviour?

由 一个人想着一个人 提交于 2019-12-14 02:33:55
问题 While trying to read an xls file using jExcelAPI, I find that the library dumps a lot of information in stderr, sometimes this information is not relevant.

JExcelApi: multiple formats in one cell?

由 坚强是说给别人听的谎言 提交于 2019-12-14 02:16:30
问题 In Excel, I can have multiple text styles in a single cell. Is there a way to create a file like this using JExcelApi?

Is there any other Excel-export library which does implement this, from which I could borrow the

问题 I have spent countless hours trying to find a solution to this. I have tried Apache POI, JExcel and JXLS but no where have I found code to successfully read checkbox (form control) values.
