本文整理了Java中java.util.zip.ZipEntry.getSize()方法的一些代码示例，展示了ZipEntry.getSize()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ZipEntry.getSize()方法的具体详情如下：
包路径：java.util.zip.ZipEntry
类名称：ZipEntry
方法名：getSize

ZipEntry.getSize介绍

[英]Gets the uncompressed size of this ZipEntry.
[中]获取此ZipEntry的未压缩大小。

代码示例

public static boolean isZipBomb(ZipEntry entry) {
  long compressedSize = entry.getCompressedSize();
  long uncompressedSize = entry.getSize();
  if (compressedSize < 0 || uncompressedSize < 0) {
    LOG.error("Zip bomb attack detected, invalid sizes: compressed {}, uncompressed {}, name {}",
        compressedSize, uncompressedSize, entry.getName());
    return true;
  }
  if (compressedSize * MAX_SIZE_DIFF < uncompressedSize) {
    LOG.error("Zip bomb attack detected, invalid sizes: compressed {}, uncompressed {}, name {}",
        compressedSize, uncompressedSize, entry.getName());
    return true;
  }
  return false;
}
