如何将ZipInputStream转换为InputStream? [英] How can I convert ZipInputStream to InputStream?

问题描述

我有将ZipInputSream转换为byte []的代码，但我不知道如何将其转换为inputstream.

I have code, where ZipInputSream is converted to byte[], but I don't know how I can convert that to inputstream.

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, 0, BUFFER)) != -1) 
    {
       // How can I convert data to InputStream  here ?                    
    }
}

推荐答案

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获取到内存中.

Here is how I solved this problem. Now I can get single files from ZipInputStream to memory as InputStream.

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;
}
