Fiz conforme o que está no vídeo mas não funciona: o erro é o seguinte:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'contaController' defined in file [C:\sts-bundle\pivotal-tc-server-developer-3.0.0.RELEASE\base-instance\wtpwebapps\contas\WEB-INF\classes\br\com\caelum\contas\controller\ContaController.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [br.com.caelum.contas.dao.ContaDAO]: : Error creating bean with name 'contaDAO' defined in file [C:\sts-bundle\pivotal-tc-server-developer-3.0.0.RELEASE\base-instance\wtpwebapps\contas\WEB-INF\classes\br\com\caelum\contas\dao\ContaDAO.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [com.springsource.tcserver.serviceability.request.DataSource]: : No qualifying bean of type [com.springsource.tcserver.serviceability.request.DataSource] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Código:

<bean id="mysqlDataSource" class="org.apache.commons.dbcp.BasicDataSource" >
        <property name="driverClassName" value="org.hsqldb.jdbcDriver"/>
        <property name="url" value="jdbc:hsqldb:file:contas.db"/>
        <property name="username" value="sa"/>
        <property name="password" value=""/>
    </bean>

ContaController

@Controller
public class ContaController {

    private final ContaDAO dao;

    @Autowired
    public ContaController(ContaDAO dao) {
        this.dao = dao;
    }
//outros metodos

ContaDAO:

@Repository
public class ContaDAO {
    private Connection connection;

    @Autowired
    public ContaDAO(DataSource ds) {
        try {
            this.connection = ds.getConnection();
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
    }
//outros métodos

Alguém sabe o que pode ser?

Resolvido: estava importando outro Datasource que não esse: import javax.sql.DataSource;
