Result Set Extractor Vs Rowmapper. ResultSetExtractor is suppose to extract the whole ResultSet possibly multiple rows while RowMapper is feeded with row at a time. It requires to extract values of the current row and process the data on per-row basis.
RowMapper and BeanPropertyRowMapper helps us to map the underline resultset object to retrieve the desired values. To wrap it up the difference between RowMapper and ResultSetExtrator is that with the mapper we have access to a returned row while with the extractor we can use the whole result set. SQLExceptions if any thrown will be caught and handled by the calling JdbcTemplate.
