java压缩文件怎么赋权到文件夹

java压缩包内的指定文件夹...

1. 压缩成ZIP 方法1 *@paramsrcDir 压缩文件夹路径 *@paramout 压缩文件输出流 *@paramKeepDirStructure 是否保留原来的目录结构,true:保留目录结构

2. 压缩成ZIP 方法2 *@paramsrcFiles 需要压缩的文件列表

import java.io.File

public class ZipCompressorByAnt {

private File zipFile

/**

* 压缩文件构造函数

* @param pathName 最终压缩生成的压缩文件：目录+压缩文件名.zip

*/

public ZipCompressorByAnt(String finalFile) {

zipFile = new File(finalFile)

}

/**

* 执行压缩 *** 作

* @param srcPathName 需要被压缩的文件/文件夹

*/

public void compressExe(String srcPathName) {

System.out.println("srcPathName="+srcPathName)

File srcdir = new File(srcPathName)

if (!srcdir.exists()){

throw new RuntimeException(srcPathName + "不存在！")

}

Project prj = new Project()

Zip zip = new Zip()

zip.setProject(prj)

zip.setDestFile(zipFile)

FileSet fileSet = new FileSet()

fileSet.setProject(prj)

fileSet.setDir(srcdir)

//fileSet.setIncludes("**/*.java")//包括哪些文件或文件夹 eg:zip.setIncludes("*.java")

//fileSet.setExcludes(...)//排除哪些文件或文件夹

zip.addFileset(fileSet)

zip.execute()

}    

}

public class TestZip {

public static void main(String[] args) {

ZipCompressorByAnt zca = new ZipCompressorByAnt("E:\\test1.zip ")

zca.compressExe("E:\\test1")

}  

}

/*如果 出现ant 的 52  51 50 等版本问题 可以去找对应的ant-1.8.2.jar     我开始用的ant-1.10.1.jar 就是这个包版本高了  一直报verson 52 版本问题*/

压缩文件夹代码:

import java.io.File

import org.apache.tools.zip.ZipOutputStream//这个包在ant.jar里，要到官方网下载

import java.io.FileInputStream

import java.io.FileOutputStream

import java.util.zip.ZipInputStream

import java.util.zip.ZipEntry

public class CompressBook {

public CompressBook() {}

/*

* inputFileName 输入一个文件夹

* zipFileName 输出一个压缩文件夹

*/

public void zip(String inputFileName) throws Exception {

String zipFileName = "c:\\test.zip"//打包后文件名字

System.out.println(zipFileName)

zip(zipFileName, new File(inputFileName))

}

private void zip(String zipFileName, File inputFile) throws Exception {

ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFileName))

zip(out, inputFile, "")

System.out.println("zip done")

out.close()

}

private void zip(ZipOutputStream out, File f, String base) throws Exception {

if (f.isDirectory()) {

File[] fl = f.listFiles()

out.putNextEntry(new org.apache.tools.zip.ZipEntry(base + "/"))

base = base.length() == 0 ? "" : base + "/"

for (int i = 0i <fl.lengthi++) {

zip(out, fl[i], base + fl[i].getName())

}

}else {

out.putNextEntry(new org.apache.tools.zip.ZipEntry(base))

FileInputStream in = new FileInputStream(f)

int b

System.out.println(base)

while ( (b = in.read()) != -1) {

out.write(b)

}

in.close()

}

}

public static void main(String [] temp){

CompressBook book = new CompressBook()

try {

book.zip("c:\\c")//你要压缩的文件夹

}catch (Exception ex) {

ex.printStackTrace()

}

}

}
