zip压缩包在解压过程中，遇到了错误，提示如下

java.lang.IllegalArgumentException: MALFORMED  
    at java.util.zip.ZipCoder.toString(Unknown Source)  
    at java.util.zip.ZipInputStream.readLOC(Unknown Source)  
    at java.util.zip.ZipInputStream.getNextEntry(Unknown Source)  
    at com.yc.utils.TestZip.extZipFileList(TestZip.java:40)  
    at com.yc.utils.TestZip.main(TestZip.java:21)  

查阅网上的资料，有一个说是编码的问题， 看看老外怎么说，参考了一下，确实是编码的问题。附上我的部分解压缩代码
public static void unzip(String zipFilePath, String targetPath)
            throws IOException {
        OutputStream os = null;
        InputStream is = null;
        ZipFile zipFile = null;
        try {
            zipFile = new ZipFile(zipFilePath,Charset.forName("GBK"));
            String directoryPath = "";
            if (null == targetPath || "".equals(targetPath)) {
                directoryPath = zipFilePath.substring(0, zipFilePath
                        .lastIndexOf("."));
            } else {
                directoryPath = targetPath;
            }
            Enumeration<?> entryEnum = zipFile.entries();
            if (null != entryEnum) {
                ZipEntry zipEntry = null;
                while (entryEnum.hasMoreElements()) {
                    zipEntry = (ZipEntry) entryEnum.nextElement();
                    if (zipEntry.getSize() > 0) {
                        // 文件
                        File targetFile = FileUtil.buildFile(directoryPath
                                + File.separator + zipEntry.getName(), false);
                        os = new BufferedOutputStream(new FileOutputStream(targetFile));
                        is = zipFile.getInputStream(zipEntry);
                        byte[] buffer = new byte[4096];
                        int readLen = 0;
                        while ((readLen = is.read(buffer, 0, 4096)) >= 0) {
                            os.write(buffer, 0, readLen);
                            os.flush();
                        }
                        is.close();
                        os.close();
                    } 
                    if (zipEntry.isDirectory()) {
                    	String pathTemp =  directoryPath + File.separator
                                + zipEntry.getName();
                    	File file = new File(pathTemp);
                    	file.mkdirs();
                        System.out.println(pathTemp);
//                        continue;
                    }
                }
            }
       } catch (IOException ex) {
            throw ex;
        } finally {
            if(null != zipFile){
            	zipFile.close();
                zipFile = null;
            }
            if (null != is) {
                is.close();
            }
            if (null != os) {
                os.close();
            }
        }
    }


声明：
zipFile = new ZipFile(zipFilePath,Charset.forName("GBK"));
不是所有压缩包的编码都是GBK，针对不同情况需要特殊处理。
