JAVA实现多文件压缩和解压缩

[使用java进行压缩和解压缩]

亲测可用：

import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.InputStream;import java.io.OutputStream;import java.util.Enumeration;import java.util.zip.ZipEntry;import java.util.zip.ZipFile;import java.util.zip.ZipOutputStream;public class TestZIP {/** * 功能:压缩多个文件成一个zip文件 * @param srcfile：源文件列表 * @param zipfile：压缩后的文件 */public static void zipFiles(File[] srcfile, File zipfile) {byte[] buf = new byte[1024];try {//ZipOutputStream类：完成文件或文件夹的压缩ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipfile));for (int i = 0; i < srcfile.length; i++) {FileInputStream in = new FileInputStream(srcfile[i]);out.putNextEntry(new ZipEntry(srcfile[i].getName()));int len;while ((len = in.read(buf)) > 0) {out.write(buf, 0, len);}out.closeEntry();in.close();}out.close();System.out.println("压缩完成.");} catch (Exception e) {e.printStackTrace();}}/** * 功能:解压缩 * @param zipfile：需要解压缩的文件 * @param descDir：解压后的目标目录 */public static void unZipFiles(File zipfile, String descDir) {try {ZipFile zf = new ZipFile(zipfile);for (Enumeration entries = zf.entries(); entries.hasMoreElements();) {ZipEntry entry = (ZipEntry) entries.nextElement();String zipEntryName = entry.getName();InputStream in = zf.getInputStream(entry);OutputStream out = new FileOutputStream(descDir + zipEntryName);byte[] buf1 = new byte[1024];int len;while ((len = in.read(buf1)) > 0) {out.write(buf1, 0, len);}in.close();out.close();System.out.println("解压缩完成.");}} catch (Exception e) {e.printStackTrace();}}/**功能: * @param args */public static void main(String[] args) {//2个源文件File f1 = new File("D:\\test\\1.csv");File f2 = new File("D:\\test\\2.xlsx");File[] srcfile = { f1, f2 };//压缩后的文件File zipfile = new File("D:\\test\\3.zip");TestZIP.zipFiles(srcfile, zipfile);//需要解压缩的文件File file = new File("D:\\test\\3.zip");//解压后的目标目录String dir = "D:\\test\\1\\";TestZIP.unZipFiles(file, dir);}}

，忘掉失败，不过要牢记失败中的教训。
