Spring MVC + ComboPooledDataSource (hibernate) - mysql

Question

It's my first time I'm using ComboPooledDataSource in hibernate, but there's something wrong with my configurations I think, so that when I call DAO to retrieve all data from database this returns me nothing.
GenView
#RequestMapping(value="/getHospitals.ajax")
public #ResponseBody Map<String,? extends Object> loadHospitals(){
HashMap<String, List<Hastaneler>> modelMap = new HashMap<String,List<Hastaneler>>();
modelMap.put("hastaneler", genBUS.getHospitals());
return modelMap;
}
GenBUS
#Service
#Transactional(isolation = Isolation.DEFAULT, readOnly = false, propagation = Propagation.REQUIRED)
public class GenBUS implements IGenBUS {
private Log log = LogFactory.getLog(GenBUS.class);
#Autowired
private SessionClientData scd;
#Autowired
private GenDAO genDAO;
private JdbcTemplate jdbcTemplate;
#Autowired
private ComboPooledDataSource comboPooledDataSource;
#PostConstruct
public void dataSource2JdbcTemplate() {
this.jdbcTemplate = new JdbcTemplate(comboPooledDataSource);
}
public GenDAO getGenDAO() {
return genDAO;
}
#Override
public List<User> getHospitals() {
return genDAO.loadAllObject(User.class);
}
GenDAO
#Repository
public class GenDAO extends BaseDAO{
private Log log = LogFactory.getLog(GenDAO.class);
#Autowired
private SessionClientData scd;
#Autowired
private ComboPooledDataSource comboPooledDataSource;
private JdbcTemplate jdbcTemplate;
#PostConstruct
public void dataSource2JdbcTemplate() {
this.jdbcTemplate = new JdbcTemplate(comboPooledDataSource);
}
#Autowired
public GenDAO(SessionFactory sessionFactory) {
logger.debug("GenDAO constructor is called !!!!!!!!");
System.out.println("genDaoooooooooooooooo.....");
setSessionFactory(sessionFactory);
}
BaseDAO
public class BaseDAO extends HibernateDaoSupport {
protected org.hibernate.impl.SessionFactoryImpl baseSessionFactory;
public<T> List<T> loadAllObject(Class<T> clazz) {
return (List<T>) getHibernateTemplate().loadAll(clazz);
}

I'm using Mysql InnoDB as database engine... Any suggestions?

Answer 1

I've solved this by changing jdbcTemplate...I reconfigured it to use my sessionFactory, and that worked :)
