mapRow

T mapRow(ResultSet rs,
         int rowNum)

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.

参数:

rs - the ResultSet to map (pre-initialized for the current row)

rowNum - the number of the current row

返回:

the result object for the current row (may be null)

抛出:

SQLException - if an SQLException is encountered getting column values (that is, there's no need to catch SQLException)
