Spring JdbcTemplate - Insert blob and return generated key

Question

From the Spring JDBC documentation, I know how to insert a blob using JdbcTemplate

final File blobIn = new File(\"spring2004.jpg\");
final InputStream blobIs

In 2012, SimpleJdbcTemplate is deprecated. This is what I did:

KeyHolder keyHolder = new GeneratedKeyHolder();

List declaredParams = new ArrayList<>();

declaredParams.add(new SqlParameter(Types.VARCHAR));
declaredParams.add(new SqlParameter(Types.BLOB));
declaredParams.add(new SqlParameter(Types.VARCHAR));
declaredParams.add(new SqlParameter(Types.INTEGER));
declaredParams.add(new SqlParameter(Types.INTEGER));

PreparedStatementCreatorFactory pscFactory = 
    new PreparedStatementCreatorFactory(SQL_CREATE_IMAGE, declaredParams);

pscFactory.setReturnGeneratedKeys(true);

getJdbcTemplate().update(
    pscFactory.newPreparedStatementCreator(
        new Object[] {
            image.getName(), 
            image.getBytes(), 
            image.getMimeType(), 
            image.getHeight(),
            image.getWidth() 
        }), keyHolder);

image.setId(keyHolder.getKey().intValue());

The SQL looks like this:

INSERT INTO image (name, image_bytes, mime_type, height, width) VALUES (?, ?, ?, ?, ?)
