java.util.Mapfor each row, representing all columns as key-value pairs: one entry for each column, with the column name as key. The Map implementation to use and the key to use for each column in the column Map can be customized through overriding {@link #createColumnMap} and {@link #getColumnKey}, respectively.
Note: By default, ColumnMapRowMapper will try to build a linked Map with case-insensitive keys, to preserve column order as well as allow any casing to be used for column names. This requires Commons Collections on the classpath (which will be autodetected). Else, the fallback is a standard linked HashMap, which will still preserve column order but requires the application to specify the column names in the same casing as exposed by the driver. @author Juergen Hoeller @since 1.2 @see JdbcTemplate#queryForList(String) @see JdbcTemplate#queryForMap(String)
