java文件压缩

使用java基本的zip库可以进行压缩，但是不支持中文文件名，会出现乱码，这里使用apache tools下的ant.jar可以解决这个问题。

压缩工具类ZipUtil代码：

package com.home;import java.io.BufferedOutputStream;import java.io.BufferedReader;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.util.zip.Adler32;import java.util.zip.CheckedOutputStream;import org.apache.tools.zip.ZipEntry;import org.apache.tools.zip.ZipOutputStream;public class ZipUtil {/** * 提供给外部压缩调用 *  * @param src * @param des * @throws IOException */public static void zip(String src, String des) throws IOException {ZipOutputStream out = null;try {CheckedOutputStream cos = new CheckedOutputStream(new FileOutputStream(des), new Adler32());out = new ZipOutputStream(new BufferedOutputStream(cos));out.setEncoding("GBK");zip(new File(src), out, "");} finally {if (out != null) {out.close();}}}/** * 压缩文件 *  * @param file * @param out * @param base * @throws IOException */private static void zip(File file, ZipOutputStream out, String base)throws IOException {if (file.isFile()) {if (base.length() > 0) {out.putNextEntry(new ZipEntry(base));} else {out.putNextEntry(new ZipEntry(file.getName()));}BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file), "ISO8859_1"));int len;while ((len = br.read()) != -1) {out.write(len);}br.close();} else if (file.isDirectory()) {File[] subFiles = file.listFiles();out.putNextEntry(new ZipEntry(base + File.separator));base = base.length() != 0 ? base + File.separator : "";if (subFiles != null) {for (File subFile : subFiles) {zip(subFile, out, base + subFile.getName());}}}}}

测试类Test：

package com.home;public class Test {/** 源文件夹路径 */private String folderSrcPath = "D://test//测试文件夹";/** 压缩后的zip文件存放路劲 */private String forderDesPath = "D://test//test1.zip";/** 源文件路径 */private String fileSrcPath = "D://test//测试.pdf";/** 压缩后的zip文件存放路劲 */private String fileDesPath = "D://test//test.zip";public Test() {try {ZipUtil.zip(folderSrcPath, forderDesPath);ZipUtil.zip(fileSrcPath, fileDesPath);} catch (Exception e) {e.printStackTrace();}}public static void main(String[] args) {new Test();}}
