easy excel复杂表头数据读取

excel数据

定义导入时的映射对象：

@Data
public class Content {
    @ExcelProperty(index = 0)
    private String field1;
    @ExcelProperty(index = 1)
    private String field2;
    @ExcelProperty(index = 2)
    private String field3;
    @ExcelProperty(index = 3)
    private String field4;
    @ExcelProperty(index = 4)
    private String field5;
    @ExcelProperty(index = 5)
    private String field6;
}

读取内容：

public class MainTest{
    public static void main(String[] args){
        ExcelReader build = EasyExcel.read(new File("/home/demo.xlsx")).build();
        SyncReadListener syncReadListener = new SyncReadListener();
        ReadSheet readSheet1 =
            EasyExcel.readSheet(0).head(Content.class).registerReadListener(syncReadListener).build();
        build.read(Arrays.asList(readSheet1));
        syncReadListener.getList().forEach(x -> System.out.println(x.toString())); 
    }
}

输出内容为：
Content(field1=null, field2=null, field3=c-sub-1, field4=c-sub-2, field5=d-sub-1, field6=d-sub-2)
Content(field1=1, field2=2, field3=3, field4=4, field5=5, field6=6)
Content(field1=6, field2=4, field3=5, field4=2, field5=2, field6=2)

此时数据已经读入，且映射完成，但是第一行数据是部分表头数据，是无效数据
