[英]How do I create a ZIP file in Java?
What is the Java equivalent to this jar command: 与此jar命令等效的Java是什么:
C:\>jar cvf myjar.jar directory
I'd like to create this jar file programmatically as I can't be assured that the jar
command will be on the system path where I could just run the external process. 我想以编程方式创建这个jar文件,因为我无法确定jar
命令将位于我可以运行外部进程的系统路径上。
Edit : All I want is to archive (and compress) a directory. 编辑 :我想要的只是归档(和压缩)一个目录。 Doesn't have to follow any java standard. 不必遵循任何java标准。 Ie: a standard zip is fine. 即:标准拉链很好。
// These are the files to include in the ZIP file
String[] source = new String[]{"source1", "source2"};
// Create a buffer for reading the files
byte[] buf = new byte[1024];
try {
// Create the ZIP file
String target = "target.zip";
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(target));
// Compress the files
for (int i=0; i<source.length; i++) {
FileInputStream in = new FileInputStream(source[i]);
// Add ZIP entry to output stream.
out.putNextEntry(new ZipEntry(source[i]));
// Transfer bytes from the file to the ZIP file
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
// Complete the entry
out.closeEntry();
in.close();
}
// Complete the ZIP file
out.close();
} catch (IOException e) {
}
