Class ColumnMapRowMapper

  • All Implemented Interfaces:

    public class ColumnMapRowMapper
    extends Object
    implements RowMapper
    RowMapper implementation that creates a java.util.Map for 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 createColumnMap(int) and getColumnKey(java.lang.String), respectively.

    • Method Detail

      • mapRow

        public Object mapRow​(ResultSet rs,
                             int rowNum)
                      throws SQLException
        Description copied from interface: RowMapper
        Implementations must implement this method to map each row of data in the ResultSet. This method should not call next() on the ResultSet; it is only supposed to map values of the current row.
        Specified by:
        mapRow in interface RowMapper
        rs - the ResultSet to map (pre-initialized for the current row)
        rowNum - the number of the current row
        the result object for the current row
        SQLException - if a SQLException is encountered getting column values (that is, there's no need to catch SQLException)
      • createColumnMap

        protected Map createColumnMap​(int columnCount)
        Create a Map instance to be used as column map.
        columnCount - the column count, to be used as initial capacity for the Map
        the new Map instance
      • getColumnKey

        protected String getColumnKey​(String columnName)
        Determine the key to use for the given column in the column Map.
        columnName - the column name (uppercase) as returned by the ResultSet
        the column key to use

      • getColumnValue

        protected Object getColumnValue​(ResultSet rs,
                                        int index)
                                 throws SQLException
        Retrieve a JDBC object value for the specified column.

        The default implementation uses the getObject method. Additionally, this implementation includes a "hack" to get around Oracle returning a non standard object for their TIMESTAMP datatype.

        rs - is the ResultSet holding the data
        index - is the column index
        the Object returned
