- Excel读取支持部分类型转换了(如转为Integer,Long,Date(部分)等) v2.0.0之前只能全部内容转为String
- Excel支持非注解读取Excel内容了,内容存于List<List>对象内
- 现在支持List<List>导出Excel了(可以不基于模板)
- Excel新增了Map数据样式映射功能(模板可以为每个key设置一个样式,具体定义为:&key, 导出Map数据的样式将与key至映射)
@ExcelField(title = "学号", order = 1)
private Long id;
@ExcelField(title = "姓名", order = 2)
private String name;
@ExcelField(title = "入学日期", order = 3)
private Date date;
@ExcelField(title = "班级", order = 4)
private Integer classes;
@ExcelField(title = "是否开除", order = 5)
private String expel;

读取Excel至String数组：
[1.0000000000001E13, 张三, 2016/01/19, 101.0, 是]
[1.0000000000002E13, 李四, 2017-11-17 10:19:10, 201.0, 否]
[1.0000000000004E13, 王二, 2017/11/17, 301.0, 否]
读取Excel至对象数组(支持类型转换)：
