根因分析

ZipException 在尝试读取或处理空的 ZIP 文件（不包含任何条目）时抛出，通常是由于下载失败或归档创建损坏。

English

ZipException is thrown when attempting to read or process a ZIP file that is empty (contains no entries), often due to a failed download or corrupted archive creation.

解决方案

  1. Verify the ZIP file integrity by checking its size and content before processing: if (zipFile.size() == 0) { throw new IOException("Empty ZIP file"); } else { try (ZipInputStream zis = new ZipInputStream(new FileInputStream(zipFile))) { ZipEntry entry = zis.getNextEntry(); if (entry == null) { throw new IOException("ZIP file has no entries"); } } }
  2. Re-download or regenerate the ZIP file from the source, ensuring the transfer is complete and the file is not truncated. Use checksums (e.g., MD5) to verify integrity.

无效尝试

常见但无效的做法:

  1. 80% 失败

    ZIP files have a specific structure; manual edits without understanding the format usually result in an invalid archive.

  2. 90% 失败

    The underlying issue (failed download or generation) remains unsolved; the new file may also be empty.
