JAVA中解压压缩包到制定文件夹工具方法

最近项目中看到一个别人写的解压压缩文件的方法，感觉不错，特此记录下来，方便与以后遇到类似问题。

 // 第一个参数就是需要解压的文件，第二个就是解压的目录
    public static boolean upZipFile(String zipFile, String folderPath) {
        ZipFile zfile = null;
        try {
            zfile = new ZipFile(zipFile);
        } catch (IOException e) {
            e.printStackTrace();
            return false;
        }
        Enumeration zList = zfile.entries();
        ZipEntry ze = null;
        byte[] buf = new byte[1024];
        while (zList.hasMoreElements()) {
            ze = (ZipEntry) zList.nextElement();
            if (ze.isDirectory()) {
                String dirstr = folderPath + ze.getName();
                dirstr.trim();
                File f = new File(dirstr);
                f.mkdir();
                continue;
            }
            OutputStream os = null;
            FileOutputStream fos = null;
            File realFile = getRealFileName(folderPath, ze.getName());
            try {
                fos = new FileOutputStream(realFile);
            } catch (FileNotFoundException e) {
                return false;
            }
            os = new BufferedOutputStream(fos);
            InputStream is = null;
            try {
                is = new BufferedInputStream(zfile.getInputStream(ze));
            } catch (IOException e) {
                return false;
            }
            int readLen = 0;
            // 进行一些内容复制操作
            try {
                while ((readLen = is.read(buf, 0, 1024)) != -1) {
                    os.write(buf, 0, readLen);
                }
            } catch (IOException e) {
                return false;
            }
            try {
                is.close();
                os.close();
            } catch (IOException e) {
                return false;
            }
        }
        try {
            zfile.close();
        } catch (IOException e) {
            return false;
        }
        return true;
    }
