OutExcel2007 v1.0.4 正式版发布 附源代码

 

POI 最新版本已经支持大数据量导出,而不会内存溢出了.  但是我测试了下.效率没有我这个高.而且CPU消耗比较高.

 

曾经放出过源码. 但是很多人,....哎不说了.这次关闭源码.

 

 

这个只是个正式版本...目前该版本.支持多sheet100W数据量的数据导出.

 

解决了Excel2007的格式导出大数据量内存溢出问题 ,

 

本工具,绝对不会出现内存溢出的问题,即使每个sheet100W数据量.导出100个这样sheet ,(100W*100 的数据量)

 

已近解决了多处BUG.再我公司大数据量系统导出里面已近运行了3个月了.没出现问题

 

下载的压缩包里面已近包含了下面的测试类了.
