EasyExcel 使用

String fileName = "C:\Users\31094\Desktop\副本电压电流曲线.xlsx";
List<IndexOrNameData> list = EasyExcel.read(fileName)
        .head(IndexOrNameData.class)
        .sheet(0)
        .headRowNumber(0) // 第0行就是数据
        // 添加时间转换器
        .registerConverter(new Converter<LocalDateTime>() {
            @Override
            public Class<?> supportJavaTypeKey() {
