功能简述

由于公司业务需求，我需要实现一个完全通过Java后台导出一个特定的Excel表格功能，为此查阅了相关资料和浏览文章。最终选定使用jxl来实现此功能。

需求

图片内黑色字体部分是写死的，黄色部分是需要数据能自由填充的。

目标

由于保密这里只实现一个demo，直接将生成的Excel文档放到指定的文件夹中。有需要的朋友，可以参考代码实现相关功能。

实现

1.首先在项目中导入jxl相关jar包，并引入

需要jar包的自行在网上搜索，或者联系我vx：yangyun1719

2.编写代码

这里仅实现了一个demo，供需要的朋友参考。由于Excel相关的东西太过麻烦。需要自定义特定表格的时候，尤为麻烦。需要首先理清思路，哪里需要合并单元格，哪里需要设置单元格样式，都需要特别小心。具体实现请参考我的代码，和网上其他文字。或者去找jxl官方文档。

后记

编写业务代码，是进公司以后必然面临的事情。有的人只研究技术部面向业务，有的人只钻研业务不懂技术。殊不知业务驱动技术，技术实现业务。无论你用的什么技术，对客户来说，最终实现了客户需求才是最好的技术。做我们这行的，很累，加班是常有之事，有时候会很迷茫，这也正常。新的技术不断更新迭代，心态包容，能接收新鲜事物会让我们更有动力。另外建议初入行的朋友培养点业余爱好，每天跟电脑打交道，难免会让我们在社交方面有所缺，尤其是夜深人静，如何自处是当代程序员面临的共同难题。如果有个爱好陪着自己度过无聊岁月，未尝不是一种幸运。
