为啥java读不了.xlsx的excel文件只能读.xls的，难道是因为我的jxl.jar包太久了？

Posted 2023-04-24

网上说最新版的下载下来也没有用，有没有大神有解决方法啊？如果有可以读.xlsx的jxl.jar请发到我的邮箱[e-mail]，万分感谢

参考技术A 建议您还是说服用户把文档格式改成2003吧。。。jxl暂时没JAR包支持2007或2010.。。
当然换POI 可行，但整个项目里凡是以前用到jxl的地方都要换。。。风险是不是太大了。。 参考技术B 兄弟 jxl不支持office2007
还是用Apache POI 插件吧本回答被提问者采纳 参考技术C 百度知道不让发网址。你在百度里搜索：大气象
在我的博客园博客里有详细代码。
