java.io.IOException：无法读取zip条目源

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

我在第二行发生错误。我看着不同的网上资源，比如这个：java.io.IOException：无法读取zip条目源

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时间，然后它开始抛出了同样的错误

任何帮助或指导表示赞赏。

如果您信任的文件，如果你把在更晚的比例会发生什么？ – Gagravarr

@Gagravarr我相信该文件，有没有办法来覆盖检查？像ZipSecureFile.setMinInflateRatio（-1.0d）; ？ – Chid

IIRC您可以设置'0'的比率来禁用检查，但只有在您信任该文件时才会这样做！ – Gagravarr

添加下面的行对我来说是个诀窍。

ZipSecureFile.setMinInflateRatio(-1.0d);

代码如下：

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