Excel模板填充：从minio上获取模板使用easyExcel填充-编程知识

最近工作中有个excel导出的功能，要求导出的模板和客户提供的模板一致，而客户提供的模板有着复杂的表头和独特列表风格，像以往使用poi去画是非常耗时间的，比如需要考虑字体大小，单元格合并，单元格的格式等问题；

所有给大家推荐使用easyExcel填充，我们只需要把客户的模板进行简单处理，上传到文件服务器，需要导出的的时候，就从文件服务器拿模板进行填充返回前端，这样非常便捷和效率高。

一、流程展示

我准备了一个简单的模板进行测试

1.1 模板准备

1.2 模板文件上传到minio

1.3 填充后的文件

二、关键代码

1.1 引入依赖minio、easyExcel

            <dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>7.1.0</version></dependency>

            <dependency><groupId>com.alibaba</groupId><artifactId>easyexcel</artifactId><version>3.1.0</version></dependency>

1.2 minio配置及工具类准备

1.2.1 minio yml文件配置

minio:endpoint: http://xxx.xxx.xxx.xxx:xxxaccesskey: xxxsecretKey: xxxbucketName: xxxexpires: 3

1.2.2 minio 配置类
