包路径:org.apache.poi.openxml4j.util.ZipInputStreamZipEntrySource
类名称:ZipInputStreamZipEntrySource

ZipInputStreamZipEntrySource介绍

[英]Provides a way to get at all the ZipEntries from a ZipInputStream, as many times as required. Allows a ZipInputStream to be treated much like a ZipFile, for a price in terms of memory. Be sure to call #close() as soon as you're done, to free up that memory!
[中]提供了一种从ZipInputStream获取所有ZipPentries的方法,可以根据需要多次获取。允许ZipInputStream像ZipFile一样被处理,以内存为代价。确保完成后立即调用#close(),以释放内存!

  try {
    // open the zip entry source stream
    return new ZipInputStreamZipEntrySource(zis);
