easyExcel/poi导出文件Can not close IO，This archive contains unclosed entries

easyExcel或poi导出文件时发生com.alibaba.excel.exception.ExcelGenerateException: Can not close IO，或者java.io.IOException: This archive contains unclosed entries.此情况只会发生导出一定数据量时，导出数据量很少时无此情况，检查发现服务磁盘、内存均富余可用，文件权限操作无问题

引发原因

根据源码分析发现是有其他线程提前关闭了请求或IO导致生成的Excel临时文件不能正确关闭；
系统部署了网关服务，由于网关服务ribbon ReadTimeout配置错误导致请求
每次超过1秒即会被熔断（ribbon超时默认1s），熔断将会导致请求被提前关闭从而导致response与outputStream被提前关闭，因而导致生成的本地Excel临时文件无法被正确写入response以及正确关闭。

解决

修改网关各类超时配置以及熔断配置，保证请求的可用有效文章来源地址https://www.toymoban.com/news/detail-568951.html
