java 关于zip文件解压工具类，后续一直更新

前几天在网上看到过这种，但是觉得还是不怎么通用，
就自己了解原理尝试的写了个工具类，希望大家多多指点，不说多了上代码了：
package com.bdt.framework.zip;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.io.*;
import java.util.Enumeration;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;

/**
 * zip 工具类
 * @author zhanghongbo
 */
public class ZipUilt {

    private static final Logger log = LoggerFactory.getLogger(ZipUilt.class);

    /**
     * 解压缩zip包
     *
     * @param zipFilePath   zip文件的全路径
     * @param unzipFilePath 解压后的文件保存的路径
     */
    @SuppressWarnings("unchecked")
    public static void unzip(String zipFilePath, String unzipFilePath) throws Exception {
        log.info("Unzipped files：{}", zipFilePath);
        //解压后的文件路径是否存在，不存在则新建
        File unzip=new File(unzipFilePath);
        if(!unzip.isDirectory()){
            log.info("create unzip files path:{}",unzipFilePath);
            unzip.mkdirs();
        }
        //开始解压
        String entryDirPath;
        ZipFile zip = null;
        InputStream is = null;
        OutputStream os = null;
        try {
            File zipFile = new File(zipFilePath);
            zip = new ZipFile(zipFile);
            Enumeration entries = zip.entries();
            //循环对压缩包里的每一个文件进行解压
            while (entries.hasMoreElements()) {
                ZipEntry entry = (ZipEntry) entries.nextElement();
                //构建压缩包中一个文件解压后保存的文件全路径
                String entryFilePath = unzipFilePath + "/" + entry.getName();
                //构建解压后保存的文件夹路径
                int index = entryFilePath.lastIndexOf("/");
                if (index != -1) {
                    entryDirPath = entryFilePath.substring(0, index);
                } else {
                    entryDirPath = "";
                }
                File entryDir = new File(entryDirPath);
                //如果文件夹路径不存在，则创建文件夹
                if (!entryDir.exists() || !entryDir.isDirectory()) {
                    log.info("Create folder path：{}", entryDirPath);
                    entryDir.mkdirs();
                    continue;
                }
                //写入文件
                byte[] buffer = new byte[4*1024];
                int len;
                os = new BufferedOutputStream(new FileOutputStream(new File(entryFilePath)));
                is = new BufferedInputStream(zip.getInputStream(entry));
                while ((len = is.read(buffer, 0, 4*1024)) != -1) {
                    os.write(buffer, 0, len);
                }
                is.close();
                log.info("===========Unzipped file ove===========:{}",entryFilePath);
            }
        } catch (Exception e) {
            log.error("Unzipped file failed, error message：{}", e);
        } finally {
            try {
                if (zip != null) {
                    zip.close();
                } else if (os != null) {
                    os.close();
                } else if (is != null) {
                    is.close();
                }
            } catch (Exception e) {
                log.error("close error：{}", e);
                e.printStackTrace();
            }
        }
    }

    public static void main(String[] args) throws Exception {
        String zipFilePath = "D:/0382cd69cd9dd647ace82c6a/0382cd69cd9dd647ace82c6a.zip";
        String unzipFilePath = "D:/test";
        try {
            unzip(zipFilePath, unzipFilePath);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}
到这里就结束了，有问题还请大家给小编提出来，谢谢！
