Flushes this output stream and forces any buffered output bytes to be written out.

Usage

From source file:mvc.controller.UsuarioController.java

private void setImagePath(List<Usuario> listaUsuarios) throws IOException {

    for (Usuario usuario : listaUsuarios) {

        BufferedImage bImage = ImageIO.read(new File(usuario.getPhoto()));
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        ImageIO.write(bImage, "jpg", baos);
        baos.flush();
        byte[] imageInByteArray = baos.toByteArray();
        baos.close();//from   w  w w.ja v  a 2s.  com
        String b64 = DatatypeConverter.printBase64Binary(imageInByteArray);
        usuario.setPhoto(b64);
