导出效果

问题记录

运行时，类找不到

Caused by: java.lang.ClassNotFoundException: org.apache.poi.ss.usermodel.WorkbookFactory$CreateWorkbook0

这种运行类找不到问题，一般就是依赖冲突了。
使用maven helper查看到poi-ooxml等相关依赖，版本冲突了。
解决：
引入依赖

    <artifactId>poiartifactId>
    <version>4.1.2version>

运行报错No valid entries or contents found, this is not a valid OOXML (Office Open XML) file

原因是maven插件打包配置了过滤文件类型
排除xlsx xls类型即可
