Question

This is my OffersDao class

package com.spring.dao;

import java.sql.*;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;
import org.springframework.stereotype.Component;

@Component
public class OffersDao {


private NamedParameterJdbcTemplate jdbc;

    @Autowired
    public void setDataSource(DataSource jdbc) {
        this.jdbc=new NamedParameterJdbcTemplate(jdbc);
    }
}
