POI - 压缩炸弹 Zip bomb

错误日志

Zip bomb detected! The file would exceed the max. ratio of compressed file size to the size of the expanded data.
This may indicate that the file is used to inflate memory usage and thus could pose a security risk.
You can adjust this limit via ZipSecureFile.setMinInflateRatio() if you need to work with files which exceed this limit.
Uncompressed size: 233647, Raw/compressed size: 2324, ratio: 0.009947
Limits: MIN_INFLATE_RATIO: 0.010000, Entry: xl/styles.xml

解决方式

Sets the ratio between de- and inflated bytes to detect zipbomb. It defaults to 1% (= 0.01d), i.e. when the compression is better than 1% for any given read package part, the parsing will fail indicating a Zip-Bomb.
