本文整理了Java中org.apache.commons.compress.archivers.zip.ZipFile.getEntry()方法的一些代码示例，展示了ZipFile.getEntry()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。ZipFile.getEntry()方法的具体详情如下：
包路径：org.apache.commons.compress.archivers.zip.ZipFile
类名称：ZipFile
方法名：getEntry

ZipFile.getEntry介绍

[英]Returns a named entry - or null if no entry by that name exists.

If multiple entries with the same name exist the first entry in the archive's central directory by that name is returned.
[中]返回一个命名条目——如果不存在同名条目，则返回null。
如果存在多个同名条目，则会返回存档中心目录中同名的第一个条目。

@Override
public ZipArchiveEntry getEntry(String path) {
  return zipFile.getEntry(path);
}

代码示例来源：origin: org.apache.poi/poi-ooxml

@Override

   final ZipArchiveEntry entry = zipArchive.getEntry(normalizedPath);
   if (entry != null) {

   // the opc spec allows case-insensitive filename matching (see #49609)
   for (final ZipArchiveEntry ze : asIterable(asIterator(zipArchive.getEntries()))) {
     if (normalizedPath.equalsIgnoreCase(ze.getName().replace('\\','/'))) {
      return ze;

   return null;
