对zip压缩包进行解压

public static Map unZipFile(String path, String zipFileName) throws IOException{

        while((entry = zis.getNextEntry())!=null && !entry.isDirectory()){
            File file = new File(path, entry.getName());
            FileOutputStream out=new FileOutputStream(file);  
            BufferedOutputStream bout=new BufferedOutputStream(out);  
            int b;  
            while((b=bin.read())!=-1){  
                bout.write(b);  
            }  
            bout.close();  
            out.close();
