本文整理了Java中java.util.zip.ZipOutputStream类的一些代码示例,展示了ZipOutputStream类的具体用法。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。ZipOutputStream类的具体详情如下:
包路径:java.util.zip.ZipOutputStream
类名称:ZipOutputStream

ZipOutputStream介绍

[英]Used to write (compress) data into zip files.

ZipOutputStream is used to write ZipEntrys to the underlying stream. Output from ZipOutputStream can be read using ZipFileor ZipInputStream.

While DeflaterOutputStream can write compressed zip file entries, this extension can write uncompressed entries as well. Use ZipEntry#setMethod or #setMethod with the ZipEntry#STORED flag.

Example

Using ZipOutputStream is a little more complicated than GZIPOutputStreambecause zip files are containers that can contain multiple files. This code creates a zip file containing several files, similar to the zip(1) utility.

OutputStream os = ... 
ZipOutputStream zos = new ZipOutputStream(new BufferedOutputStream(os)); 
try { 
for (int i = 0; i < fileCount; ++i) { 
String filename = ... 
byte[] bytes = ... 
ZipEntry entry = new ZipEntry(filename); 
zos.putNextEntry(entry); 
zos.write(bytes); 
zos.closeEntry(); 
} 
} finally { 
zos.close(); 
}

[中]用于将数据写入(压缩)zip文件。
ZipOutStream用于将ZipPentry写入底层流。可以使用ZipFile或ZipInputStream读取ZipOutStream的输出。
虽然DeflaterOutputStream可以写入压缩的zip文件条目,但这个扩展也可以写入未压缩的条目。使用ZipEntry#setMethod或#setMethod与ZipEntry#STORED标志。
####范例
使用ZipOutputStream比使用GZipOutputStream要复杂一些,因为zip文件是可以包含多个文件的容器。这段代码创建了一个包含多个文件的zip文件,类似于zip(1)实用程序。

OutputStream os = ... 
ZipOutputStream zos = new ZipOutputStream(new BufferedOutputStream(os)); 
try { 
for (int i = 0; i < fileCount; ++i) { 
String filename = ... 
byte[] bytes = ... 
ZipEntry entry = new ZipEntry(filename); 
zos.putNextEntry(entry); 
zos.write(bytes); 
zos.closeEntry(); 
} 
} finally { 
zos.close(); 
}
