最近看了自己玩过的很多项目，忽然发现有一个在实际开发中我们经常用到的功能，但是我没有正儿八经的玩过这个功能，那就是在Spring Boot中实现一个excel报表的导入导出功能，这篇博客，主要是围绕excel报表数据导入进行，感兴趣的可以看看，有能力的可以在本篇博客的基础上进行改造，实现一个前端报表导入导出功能。
要在Spring Boot中使用Apache POI导入Excel数据到MySQL，我们需要一步一步来，接下来这些是我们的主要步骤。
- 引入依赖：我们需要确保pom.xml中包含了Apache POI和相关依赖。
- 配置数据源：在Spring Boot的配置文件application.properties或者application.yml中配置MySQL数据源。
- 创建相关实体类：创建一个实体类来映射数据库中对应的表。
- 创建相关接口：用来实现相关的业务功能。
- 创建相关接口实现类
- 新建一个excel表格，填充数据
- 创建对应数据库和数据库表：实际上这一步是放在第二位的，先有表在有实体类
- 测试功能是否实现
文件目录如下：

}在这个service类中，我们可以通过从Windows桌面上获取我们需要导入数据到mysql的excel文件，
"C:\\Users\\29283\\Desktop\\test.xlsx" 表示你存放excel文件的路径，"sheet1"表示excel的第一个工作薄。详细描述我在具体的方法中有进行概述，并且通过多种方式进行数据导入，请根据需要进行选择你想导入的方式。
