默认读是用XSSFWorkBook吗，怎么改成HSSFWorkBook
异常：The supplied data appears to be in the OLE2 Format. You are calling the part of POI that deals with OOXML (Office Open XML) Documents.You need to call a different part of POI to process this data (eg HSSF instead of XSSF)
// 写法1：JDK8+ ,不用额外写一个DemoDataListener
// since: 3.0.0-beta1
String fileName = TestFileUtil.getPath() + "demo" + File.separator + "demo.xlsx";
// 这里默认每次会读取100条数据 然后返回过来 直接调用使用数据就行
// 具体需要返回多少行可以在PageReadListener的构造函数设置
EasyExcel.read(fileName, DemoData.class, new PageReadListener(dataList -> {
for (DemoData demoData : dataList) {
log.info("读取到一条数据{}", JSON.toJSONString(demoData));
}
})).sheet().doRead();
