Create the entry in the database:
For this we will take flight database and flight entity as our pojo class.
See - Create flights in database and corresponding pojo class
Now using the ResultSetExtractor
First we will implement result set extractor
public class FlightResultSetExtractor implements ResultSetExtractor<List<Flight>> {
@Override
public Object extractData(ResultSet rs) throws SQLException {
List<Flight> flightList = new ArrayList<Flight>();
while(rs.next){
Flight flight = new Flight();
flight.setFlightNo(rs.getString(1));
flight.setCarrierName(rs.getString(2));
flightList.add(flight);
}
return list;
}
}
Now using the ResultSetExtractor
Initialize JdbcTemplate as jdbcTemplate first
public List<Flight> getAllTodaysFlight(){
String sql = "Get all flights where date=?";
Date today = getTodaysDate();
Object[] args = {date};
FlightResultSetExtractor extractor = new FlightResultSetExtractor();
return jdbcTemplate.query(src, args, extractor);
}
