Hi All,
I am trying to integrate vaadin with hibernate and spring. I am trying to persiste the data and at a same time trying to display it in table. But at run time, table doesn’t show any record.When I check the Db table, there also I am not able to find any record. But I am not getting any error also in console. Please help me to solve the issue.
Following are the related code Snippets.
Domain class user
@Entity
@Table(name = "user")
public class User implements Serializable {
/**
*
*/
private static final long serialVersionUID = 8496087166198616020L;
private String userId;
private String userName;
private Integer age;
private Boolean registered;
@Id
@GeneratedValue(generator = "system-uuid")
@GenericGenerator(name = "system-uuid", strategy = "uuid")
@Column(name = "userId")
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
@Column(name = "userName", nullable=false)
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
@Column(name = "age")
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
@Column(name = "registered", nullable=false)
public Boolean getRegistered() {
return registered;
}
public void setRegistered(Boolean registered) {
this.registered = registered;
}
}
DaoImpl class
@Repository("userDao")
@Transactional
public class UserDaoImpl implements UserDao {
private HibernateTemplate hibernateTemplate;
@Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
hibernateTemplate = new HibernateTemplate(sessionFactory);
}
@Transactional
public void saveUser(User user) {
hibernateTemplate.saveOrUpdate(user);
}
//@Transactional
public void deleteUser(User user) {
System.out.println("delete is called********************");
hibernateTemplate.delete(user);
}
@SuppressWarnings("unchecked")
public List<User> getAllUser(User user) {
return (List<User>) hibernateTemplate.find("from "
+ User.class.getName());
}
public User selectUserById(String userId) {
return hibernateTemplate.get(User.class, userId);
}
}

Vaadin main class
@Override
public void init() {
Window mainWindow = new Window("Vaadinspring Application");
Label label = new Label("Hello Vaadin user");
mainWindow.addComponent(label);
SpringContextHelper helper = new SpringContextHelper();
UserDao bean = (UserDao) helper.getBean("myUserDao");
User user = new User();
user.setAge(28);
user.setUserName("Vikram");
user.setRegistered(true);
bean.saveUser(user);
UserTable uTable=new UserTable(this);
mainWindow.addComponent(uTable);
setMainWindow(mainWindow);
}
User Table class
@SuppressWarnings("serial")
public class UserTable extends Table {
public UserTable(){
}
List<User> myUserList;
private UserDao myUserListBean;
public UserDao getMyUserListBean() {
return myUserListBean;
}
public void setMyUserListBean(UserDao myUserListBean) {
System.out.println("I am here, bean=" + myUserListBean);
this.myUserListBean = myUserListBean;
}
public List<User> getMyUserList() {
return myUserList;
}
public void setMyUserList(List<User> myUserList) {
this.myUserList = myUserList;
}
public UserTable(VaadinspringApplication app){
setSizeFull();
SpringContextHelper helper = new SpringContextHelper();
myUserListBean = (UserDao) helper.getBean("myUserDao");
myUserList = myUserListBean.getAllUser(new User());
BeanItemContainer<User> container = new BeanItemContainer<User>(User.class);
for (User o : myUserList) {
container.addBean(o);
}
this.setContainerDataSource(container);
}
}Please provide some input to solve this issue.I am using hibernate version 3.6.0 and Spring version 3.0.4 and MySQL as Database.
