本文整理了Java中java.util.zip.GZIPOutputStream类的一些代码示例，展示了GZIPOutputStream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。GZIPOutputStream类的具体详情如下：
包路径：java.util.zip.GZIPOutputStream
类名称：GZIPOutputStream
[英]The GZIPOutputStream class is used to write data to a stream in the GZIP storage format.
Using GZIPOutputStream is a little easier than ZipOutputStreambecause GZIP is only for compression, and is not a container for multiple files. This code creates a GZIP stream, similar to the gzip(1) utility.
OutputStream os = ...
byte[] bytes = ...
GZIPOutputStream zos = new GZIPOutputStream(new BufferedOutputStream(os));
try {
zos.write(bytes);
} finally {
zos.close();
}[中]GZIPOutputStream类用于将数据写入GZIP存储格式的流。
####范例
使用GZIPOutputStream比使用ZipOutputStream简单一些，因为GZIP只用于压缩，而不是多个文件的容器。这段代码创建了一个GZIP流，类似于GZIP（1）实用程序。
OutputStream os = ...
byte[] bytes = ...
GZIPOutputStream zos = new GZIPOutputStream(new BufferedOutputStream(os));
try {
zos.write(bytes);
} finally {
zos.close();
