10余年的吴兴网站建设经验,针对设计、前端、开发、售后、文案、推广等六对一服务,响应快,48小时及时工作处理。全网整合营销推广的优势是能够根据用户设备显示端的尺寸不同,自动调整吴兴建站的显示方式,使网站能够适用不同显示终端,在浏览器中调整网站的宽度,无论在任何一种浏览器上浏览网站,都能展现优雅布局与设计,从而大程度地提升浏览体验。成都创新互联公司从事“吴兴网站设计”,“吴兴网站推广”以来,每个客户项目都认真落实执行。
代码如下:
package com.lanyuan.assembly.util; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.util.Enumeration; import org.apache.tools.zip.ZipEntry; import org.apache.tools.zip.ZipFile; /** * 解压Zip文件工具类 * @author zhangyongbo * */ public class ZipUtil { private static final int buffer = 2048; /** * 解压Zip文件 * @param path 文件目录 */ public static void unZip(String path) { int count = -1; String savepath = ""; File file = null; InputStream is = null; FileOutputStream fos = null; BufferedOutputStream bos = null; savepath = path.substring(0, path.lastIndexOf(".")) + File.separator; //保存解压文件目录 new File(savepath).mkdir(); //创建保存目录 ZipFile zipFile = null; try { zipFile = new ZipFile(path,"gbk"); //解决中文乱码问题 Enumeration> entries = zipFile.getEntries(); while(entries.hasMoreElements()) { byte buf[] = new byte[buffer]; ZipEntry entry = (ZipEntry)entries.nextElement(); String filename = entry.getName(); boolean ismkdir = false; if(filename.lastIndexOf("/") != -1){ //检查此文件是否带有文件夹 ismkdir = true; } filename = savepath + filename; if(entry.isDirectory()){ //如果是文件夹先创建 file = new File(filename); file.mkdirs(); continue; } file = new File(filename); if(!file.exists()){ //如果是目录先创建 if(ismkdir){ new File(filename.substring(0, filename.lastIndexOf("/"))).mkdirs(); //目录先创建 } } file.createNewFile(); //创建文件 is = zipFile.getInputStream(entry); fos = new FileOutputStream(file); bos = new BufferedOutputStream(fos, buffer); while((count = is.read(buf)) > -1) { bos.write(buf, 0, count); } bos.flush(); bos.close(); fos.close(); is.close(); } zipFile.close(); }catch(IOException ioe){ ioe.printStackTrace(); }finally{ try{ if(bos != null){ bos.close(); } if(fos != null) { fos.close(); } if(is != null){ is.close(); } if(zipFile != null){ zipFile.close(); } }catch(Exception e) { e.printStackTrace(); } } } /*public static void main(String[] args) { unZip("F:\\110000002.zip"); String f = "F:\\110000002"; File file = new File(f); String[] test=file.list(); for(int i=0;i上面是第一种的代码示例,接着是另外一种,代码如下:
import java.io.*; import java.nio.charset.Charset; import java.util.Enumeration; import java.util.zip.ZipEntry; import java.util.zip.ZipFile; /** * Created by wzj on 2016/9/9. */ public class UZipFile { /** * 解压到指定目录 */ public static void unZipFiles(String zipPath,String descDir)throws IOException { unZipFiles(new File(zipPath), descDir); } /** * 解压文件到指定目录 */ @SuppressWarnings("rawtypes") public static void unZipFiles(File zipFile,String descDir)throws IOException { File pathFile = new File(descDir); if(!pathFile.exists()) { pathFile.mkdirs(); } //解决zip文件中有中文目录或者中文文件 ZipFile zip = new ZipFile(zipFile, Charset.forName("GBK")); for(Enumeration entries = zip.entries(); entries.hasMoreElements();) { ZipEntry entry = (ZipEntry)entries.nextElement(); String zipEntryName = entry.getName(); InputStream in = zip.getInputStream(entry); String outPath = (descDir+zipEntryName).replaceAll("\\*", "/");; //判断路径是否存在,不存在则创建文件路径 File file = new File(outPath.substring(0, outPath.lastIndexOf('/'))); if(!file.exists()) { file.mkdirs(); } //判断文件全路径是否为文件夹,如果是上面已经上传,不需要解压 if(new File(outPath).isDirectory()) { continue; } //输出文件路径信息 System.out.println(outPath); OutputStream out = new FileOutputStream(outPath); 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("******************解压完毕********************"); } public static void main(String[] args) throws IOException { /** * 解压文件 */ File zipFile = new File("d:/资料.zip"); String path = "d:/zipfile/"; unZipFiles(zipFile, path); } }测试结果
