使用 apache ant 轻松实现文件压缩/解压缩(转)

原文地址:http://blog.csdn.net/irvine007/article/details/6779492

maven配置ant包:

<dependency>
<groupId>org.apache.ant</groupId>
<artifactId>ant</artifactId>
<version>1.9.7</version>
</dependency>

java代码实现:

import java.io.File;
import org.apache.tools.ant.BuildException;
import org.apache.tools.ant.Project;
import org.apache.tools.ant.taskdefs.Expand;
import org.apache.tools.ant.taskdefs.Zip;
import org.apache.tools.ant.types.FileSet; /**
* [压缩/解压缩]文件和文件夹
*/
public class Zipper { public final static String encoding = "GBK"; /**
* 压缩文件和文件夹
*
* @param srcPathname 需要被压缩的文件或文件夹路径
* @param zipFilepath 将要生成的zip文件路径
* @throws BuildException
* @throws RuntimeException
*/
public static void zip(String srcPathname, String zipFilepath) throws BuildException, RuntimeException {
File file = new File(srcPathname);
if (!file.exists()) {
throw new RuntimeException("source file or directory " + srcPathname + " does not exist.");
} Project proj = new Project();
FileSet fileSet = new FileSet();
fileSet.setProject(proj);
// 判断是目录还是文件
if (file.isDirectory()) {
fileSet.setDir(file);
// ant中include/exclude规则在此都可以使用
// 比如:
// fileSet.setExcludes("**/*.txt");
// fileSet.setIncludes("**/*.xls");
} else {
fileSet.setFile(file);
} Zip zip = new Zip();
zip.setProject(proj);
zip.setDestFile(new File(zipFilepath));
zip.addFileset(fileSet);
zip.setEncoding(encoding);
zip.execute(); System.out.println("compress successed.");
} /**
* 解压缩文件和文件夹
*
* @param zipFilepath 需要被解压的zip文件路径
* @param destDir 将要被解压到哪个文件夹
* @throws BuildException
* @throws RuntimeException
*/
public static void unzip(String zipFilepath, String destDir) throws BuildException, RuntimeException {
if (!new File(zipFilepath).exists()) {
throw new RuntimeException("zip file " + zipFilepath + " does not exist.");
} Project proj = new Project();
Expand expand = new Expand();
expand.setProject(proj);
expand.setTaskType("unzip");
expand.setTaskName("unzip");
expand.setEncoding(encoding); expand.setSrc(new File(zipFilepath));
expand.setDest(new File(destDir));
expand.execute(); System.out.println("uncompress successed.");
} }
