  • Example With JdbcDaoSupport

    By extended the JdbcDaoSupport, set the datasource and JdbcTemplate in your class is no longer required, you just need to inject the correct datasource into JdbcCustomerDAO. And you can get the JdbcTemplate by using a getJdbcTemplate() method.

    public class JdbcCustomerDAO extends JdbcDaoSupport implements CustomerDAO
    {
       //no need to set datasource here
       public void insert(Customer customer){
    
        String sql = "INSERT INTO CUSTOMER " +
            "(CUST_ID, NAME, AGE) VALUES (?, ?, ?)";
    
        getJdbcTemplate().update(sql, new Object[] { customer.getCustId(),
                customer.getName(),customer.getAge()
        });
    
    }
