问题描述

这是我解决此问题的方法。现在，我可以将单个文件从ZipInputStream作为InputStream传输到内存。

private InputStream convertZipInputStreamToInputStream(ZipInputStream in, ZipEntry entry, String encoding) throws IOException
{
    final int BUFFER = 2048;
    int count = 0;
    byte data[] = new byte[BUFFER];
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    while ((count = in.read(data, 0, BUFFER)) != -1) {
        out.write(data);
    }       
    InputStream is = new ByteArrayInputStream(out.toByteArray());
    return is;
}

解决方法

private void convertStream(String encoding,ZipInputStream in) throws IOException,UnsupportedEncodingException
{
    final int BUFFER = 1;
    @SuppressWarnings("unused")
    int count = 0;
    byte data[] = new byte[BUFFER];
    while ((count = in.read(data,BUFFER)) != -1) 
    {
       // How can I convert data to InputStream  here ?                    
    }
}
