无法使用spring + apache-poi上传excel文件
当我尝试上传excel文件（.xls / .xlsx）时，我遇到以下异常：
org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF)

有人建议我，如果有任何遗漏导致上述异常？
1 个答案:
答案 0 :(得分：2)
正如@Luke建议的那样，我在代码中进行了以下更改，以适应excel文件xls和xlsx
Workbook offices;
String lowerCaseFileName = file.getOriginalFilename().toLowerCase();
if (lowerCaseFileName.endsWith(".xlsx")) {
offices = new XSSFWorkbook(file.getInputStream());
} else {
offices = new HSSFWorkbook(file.getInputStream());
}
因为，我正在验证上述代码之前的文件类型。因此，只有两个方案.xls或.xlsx。
此外，我已经包含以下库以使其工作
希望这会节省一些人的时间。
