easyExcel使用报错

报错信息

easyexcel The maximum length of cell contents (text) is 32,767 characters

使用easyexcel向excel中写内容出现了单元格大小不能超过32,767的限制，这是因为excel 2007限制单个cell不能超过32767个字符

解决办法
重写poi包下SpreadsheetVersion类
在自己的项目文件夹下创建org.apache.poi.ss.SpreadsheetVersion 类，复制poi中的该类源码，excel2007中的最后一个值改为int类型最大值。重试导出问题解决。
