Some doubts about RowMapper use in JDBC in a Spring Framework application

Question

I am studying how to execute query on a database using JDBC in Spring Framework.

I am following this tutorial: http://www.tutorialspoint.com/spring/spring_jdbc_example.h

Answer 1

Using RowMapper in Spring

import java.sql.ResultSet;
import java.sql.SQLException;

import org.springframework.jdbc.core.RowMapper;

public class RowsMap implements RowMapper{

    @Override
    public EmpPojo mapRow(ResultSet rs, int counts) throws SQLException {
        EmpPojo em=new EmpPojo();
        em.setEid(rs.getInt(1));
        em.setEname(rs.getString(2));
        em.setEsal(rs.getDouble(3));

        return em;
    }

}

Finally in Main class

List lm=jt.query("select * from emps", new RowsMap());
for(EmpPojo e:lm)
{
    System.out.println(e.getEid()+" "+e.getEname()+" "+e.getEsal());
}
