InputStream转ByteArrayOutputStream主要用来解决从网络上获取InputStream中断的问题。

public static void main(String[] args) throws IOException {
        InputStream inputStream = new FileInputStream(new File("c:\\logo.jpg"));//原始输入流
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        byte[] buffer = new byte[1024];
        int len;
        byte[] dataBytes;
        while ((len = inputStream.read(buffer)) != -1 ) {  
            baos.write(buffer, 0, len);  
        }
        baos.flush();
        dataBytes = baos.toByteArray();
        InputStream is = new ByteArrayInputStream(dataBytes);//转换后的输入流
}
