import java.util.List;
import java.util.Map;

import javax.sql.DataSource;

import org.springframework.context.ApplicationContext;
import org.springframework.jdbc.core.namedparam.MapSqlParameterSource;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;

public class NamedParameterMapSourceTest {

   @param args
  public static void main(String[] args) {
     * Initialize context and get the NamedParameterJdbcTemplate
    ApplicationContext appContext = new ClassPathXmlApplicationContext("applicationContext.xml");
    DataSource dataSource = (DataSourceappContext.getBean("dataSource");
    NamedParameterJdbcTemplate template = new NamedParameterJdbcTemplate(dataSource);

    MapSqlParameterSource namedParameters = new MapSqlParameterSource("start_id"1);
    List<Map<String, Object>> rows = template.queryForList(
        "select ID, NAME, AGE from USER where ID >= :start_id and ID < :end_id"


It gives the following output,
[{ID=1, NAME=Sriram, AGE=2}, {ID=2, NAME=Anu, AGE=28}]
