java - ZipInputStream 和 OutOfMemoryError

Question

读取 6 MB（未压缩 25 MB）的 zip 文件时，我遇到了 OutOfMemoryError。我只有在通过遍历条目获取流时出现错误，如果我使用ZipFile.getInputStream(ZipEntry).

例如，这是有效的：

ZipFile zip = new ZipFile(file);
ZipEntry entry = zip.getEntry("file.xml");

InputStream is = zip.getInputStream(entry);

// Do stuff with is (loading the xml file in memory)

这不是：

ZipInputStream zis = new ZipInputStream(new FileInputStream(file));
ZipEntry entry = zis.getNextEntry();

while(entry != null) {
    if(entry.getName().equals("file.xml")) {
        // Do stuff with zis (loading the xml file in memory)
    }
    entry = zis.getNextEntry();
}
zis.close();

有谁知道为什么？

谢谢
