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

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
hystrix: command: default: execution: timeout: enabled: true isolation: strategy: SEMAPHORE #开启spring fegin本地线程共享策略，用于fegin调用其他服务时传递请求头信息 thread: timeoutInMilliseconds: 800000ribbon: ReadTimeout: 300000 # 请求处理的超时时间 ConnectTimeout: 3000 # 请求连接的超时时间 SocketTimeout: 300000 MaxAutoRetries: 1 # 对当前实例的重试次数 MaxAutoRetriesNextServer: 1 # 切换实例的重试次数 OkToRetryOnAllOperations: true # 对所有操作请求都进行重试来源地址：https://blog.csdn.net/weixin_39809420/article/details/128639726
