Spring + JdbcTemplate + JdbcDaoSupport examples

In Spring JDBC development, you can use JdbcTemplate and JdbcDaoSupport classes to simplify the overall database operation processes.

In this tutorial, we will reuse the last Spring + JDBC example, to see the different between a before (No JdbcTemplate support) and after (With JdbcTemplate support) example.

1. Example Without JdbcTemplate

Witout JdbcTemplate, you have to create many redundant codes (create connection , close connection , handle exception) in all the DAO database operation methods – insert, update and delete. It just not efficient, ugly, error prone and tedious.

	private DataSource dataSource;
	public void setDataSource(DataSource dataSource) {
		this.dataSource = dataSource;
	public void insert(Customer customer){
		String sql = "INSERT INTO CUSTOMER " +
				"(CUST_ID, NAME, AGE) VALUES (?, ?, ?)";
		Connection conn = null;
		try {
			conn = dataSource.getConnection();
			PreparedStatement ps = conn.prepareStatement(sql);
			ps.setInt(1, customer.getCustId());
			ps.setString(2, customer.getName());
			ps.setInt(3, customer.getAge());
		} catch (SQLException e) {
			throw new RuntimeException(e);
		} finally {
			if (conn != null) {
				try {
				} catch (SQLException e) {}

2. Example With JdbcTemplate

With JdbcTemplate, you save a lot of typing on the redundant codes, becuase JdbcTemplate will handle it automatically.

	private DataSource dataSource;
	private JdbcTemplate jdbcTemplate;
	public void setDataSource(DataSource dataSource) {
		this.dataSource = dataSource;
	public void insert(Customer customer){
		String sql = "INSERT INTO CUSTOMER " +
			"(CUST_ID, NAME, AGE) VALUES (?, ?, ?)";
		jdbcTemplate = new JdbcTemplate(dataSource);
		jdbcTemplate.update(sql, new Object[] { customer.getCustId(),

See the different?

3. 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(),
<beans xmlns="http://www.springframework.org/schema/beans"
	<bean id="dataSource" 
		<property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<property name="url" value="jdbc:mysql://localhost:3306/mkyongjava" />
		<property name="username" value="root" />
		<property name="password" value="password" />
<beans xmlns="http://www.springframework.org/schema/beans"
	<bean id="customerDAO" class="com.mkyong.customer.dao.impl.JdbcCustomerDAO">
		<property name="dataSource" ref="dataSource" />
In Spring JDBC development, it’s always recommended to use JdbcTemplate and JdbcDaoSupport, instead of coding JDBC code yourself.

    Can we create a GenericDao that extends the jdbcDaoSupport and then inyect it to other Daos ?

    Hi, nice post. Can u tell me how to create a GenericDao that extends the jdbc template and then inyect it to other Daos. Ty

    I have followed this guide, but apparently I am using an Oracle database so instead of this:

    I used this:

    Everything is good, aside from the fact that when I call:

    the getJdbcTemplate() returns null.
    How do I debug where is the error? I am pretty sure that the values I insert in the xml file are correct because I used those values in a normal jdbc.

    Thanks in advance.

    Before using JdbcDaoSupport, my beans were autowired in the test class and all tests were passing. But after implementing JdbcDaoSupport, the beans are not getting injected to the test classed and my tests are not passing. If I use applicationContext and get the bean, I am getting the bean but as proxy.

    Can you please let me know what could be wrong?

    such as

    &lt;bean id=&quot;dataSource2&quot; 
    		&lt;property name=&quot;driverClassName&quot; value=&quot;com.mysql.jdbc.Driver&quot; /&gt;
    		&lt;property name=&quot;url&quot; value=&quot;jdbc:mysql://localhost:8808/takaDB&quot; /&gt;
    		&lt;property name=&quot;username&quot; value=&quot;root&quot; /&gt;
    		&lt;property name=&quot;password&quot; value=&quot;123456&quot; /&gt;

    hmmmmmmmmmmm nice usage of jdbcTemplate
    well wat is your CustomerDAO code can you show it…

    mostly i use samething like that in spring





    and in code of DAO class simply use hibernate session

    SessionFactory sessionFactory = null;
    Session session = null;
    BasicQuestionair basicQuestionair;

    * @param sessionFactory
    public campusDAO(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;

    * @param entity
    * BasicQuestionair entity to persist
    * @throws RuntimeException
    * when the operation fails
    public void createcampus(campus entity) {
    LoogingHelper.log(“Try to saving BasicQuestionair instance”,
    Level.INFO, null);
    try {
    session = getSession();
    Transaction tx = session.beginTransaction();
    LoogingHelper.log(“save successful”, Level.INFO, null);
    } catch (HibernateException re) {
    LoogingHelper.log(“save failed”, Level.SEVERE, re);
    throw re;

    simply use of hibernate in spring
