今天在解析支付宝的对账单zip包时（我的系统是GBK），发现抛出以下异常：

我的方法如下，所用的jar包是rt.jar。

public static void zipDecompressing(String directory,String localPath){
            try {
                ZipInputStream Zin=new ZipInputStream(new FileInputStream(
                        directory), Charset.forName("gbk"));//输入源zip路径
                BufferedInputStream Bin=new BufferedInputStream(Zin);
                String Parent=localPath; //输出路径（文件夹目录）
                File Fout=null;
                ZipEntry entry;
                try {
                    while((entry = Zin.getNextEntry())!=null && !entry.isDirectory()){
                        Fout=new File(Parent,entry.getName());
                        if(!Fout.exists()){
                            (new File(Fout.getParent())).mkdirs();
                        }
                        FileOutputStream out=new FileOutputStream(Fout);
                        BufferedOutputStream Bout=new BufferedOutputStream(out);
                        int b;
                        while((b=Bin.read())!=-1){
                            Bout.write(b);
                        }
                        Bout.close();
                        out.close();
                        System.out.println(Fout+"解压成功");
                    }
                    Bin.close();
                    Zin.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

ZipInputStream Zin=new ZipInputStream(new FileInputStream(  
directory), Charset.forName(“gbk”));//输入源zip路径  
这一行就可以解决zip包中包含中文文件名的需要。
