JEasyPoi (Excel和 Word简易工具类)

1.设计精巧,使用简单
2.接口丰富,扩展简单
3.默认值多,write less do more
4.AbstractView 支持,web导出可以简单明了

1.ExcelExportUtil Excel导出(普通导出,模板导出)
2.ExcelImportUtil Excel导入
3.WordExportUtil  Word导出(只支持docx ,doc版本poi存在图片的bug,暂不支持)

1.导出时间XLS比XLSX快2-3倍
2.导出大小XLS是XLSX的2-3倍或者更多
3.导出需要综合网速和本地速度做考虑^~^

1.easypoi 父包--作用大家都懂得
2.easypoi-base 导入导出的工具包,可以完成Excel导出,导入,Word的导出,Excel的导出功能
3.easypoi-web  耦合了spring-mvc 基于AbstractView,极大的简化spring-mvc下的导出功能
4.sax 导入使用xercesImpl这个包(这个包可能造成奇怪的问题哈),word导出使用poi-scratchpad,都作为可选包了
