#rowmapper

A coworker and I were chatting regarding spring rowMappers and I did a little more research and found the following: Spring's simpleJdbcTemplate deprecated methods with parameterizedRowMapper in spring 3. The class ParameterizedRowMapper is not deprecated. Spring's jdbcTemplate however only has methods that take RowMapper<T> so it will continue to work with parameterizedRowMapper. But it seems to me the direction of Spring is to go back to use genericized rowMapper e.g. RowMapper<T>. So for all of my new mappers, I will probably implement RowMapper<T> instead of ParameterizedRowMapper<T>.

public static boolean doesColumnExist(String columnName, ResultSet rs) throws SQLException{ ResultSetMetaData meta = rs.getMetaData(); int numCol = meta.getColumnCount(); for (int i = 1; i <= numCol; i++) { if(meta.getColumnName(i).equalsIgnoreCase(columnName)) { return true; } } return false; }
