An interface used by
for mapping rows of a
on a per-row basis. Implementations of this
interface perform the actual work of mapping each row to a result object,
but don't need to worry about exception handling.
will be caught and handled
by the calling JdbcTemplate.
Typically used either for
JdbcTemplate's query methods
or for out parameters of stored procedures. RowMapper objects are
typically stateless and thus reusable; they are an ideal choice for
implementing row-mapping logic in a single place.
Alternatively, consider subclassing
MappingSqlQuery from the
jdbc.object package: Instead of working with separate
JdbcTemplate and RowMapper objects, you can build executable query
objects (containing row-mapping logic) in that style.
