J-Excel 万能的Excel导入导出工具

=======

• Universal Excel import and export tools.

• Support is derived from the List<Map>.

• Support from the List<POJO> import and export.

• Support from inside the List<POJO and List<POJO> inside> import and export.

• To support the export of similar curriculum structure type cross table.

• Support for Internationalization.

• Don't write a configuration file.

• Use the adapter pattern, data import and export support arbitrary types, users can also write your own adapter custom data types!

• 万能的Excel导入导出工具.

• 支持从List<Map>中导出.

• 支持从List<POJO>中导入导出.

• 支持从List<POJO里面还有List<POJO>>中导入导出.

• 支持导出类似课程表结构类型纵表.

• 支持国际化.

• 支持数据字典.

• 支持单元格中下拉框数据校验.

• 支持自动标红错误的数据.

• 支持模板校验，用hash值相加校验模板中的数据是否被改动过.

• 支持自由交换表格中的行或者列.

• 不写一个配置文件.

• 用到了适配器模式，支持任意类型的数据导入导出，用户还可以自己编写适配器操作自定义的数据类型！
