java.io.IOException：無法讀取zip條目源

FileInputStream file = new FileInputStream("/file/path/report.xlsx"); 
XSSFWorkbook wb = new XSSFWorkbook(file); --!ERROR LINE!--

我在第二行發生錯誤。我看着不同的網上資源，比如這個：java.io.IOException：無法讀取zip條目源

Error reading Excel .XLSX with Apache POI

我加入ZipSecureFile.setMinInflateRatio（0.009）;

FileInputStream file = new FileInputStream("/file/path/report.xlsx"); 
    ZipSecureFile.setMinInflateRatio(0.009); 
    XSSFWorkbook wb = new XSSFWorkbook(file);

它能正常工作了一段時間，然後它開始拋出了同樣的錯誤

任何幫助或指導表示讚賞。

如果您信任的文件，如果你把在更晚的比例會發生什麼？ – Gagravarr

@Gagravarr我相信該文件，有沒有辦法來覆蓋檢查？像ZipSecureFile.setMinInflateRatio（-1.0d）; ？ – Chid

IIRC您可以設置'0'的比率來禁用檢查，但只有在您信任該文件時纔會這樣做！ – Gagravarr

添加下面的行對我來說是個訣竅。

ZipSecureFile.setMinInflateRatio(-1.0d);

代碼如下：

FileInputStream file = new FileInputStream("/file/path/report.xlsx"); 
ZipSecureFile.setMinInflateRatio(-1.0d); 
XSSFWorkbook wb = new XSSFWorkbook(file);
