I'm really new in Java world and scpecificly in Spring. I try to read a lot of tutoriel but I'm really confused. I create some entity mapped by annotation, I succed to persist it when I load my Application Context in a main class but I can't do it in my controller.
@Entity
@Table(name = "User")
public class User implements Serializable{
@Id
@GeneratedValue
@Column(name = "id_user")
private Long idUser;
@Column(name = "first_name", nullable=false)
private String firstName;
@Column(name = "last_name", nullable=false)
private String lastName;
@Column(name = "email", nullable=false)
private String email;
@Column(name = "password", nullable=false)
private String password;
@Column(name = "birth")
private Date birth;
@Column(name = "avatar")
private String avatar;
...
}
I have make sur to use javax.persistence.
In my dispachtcher servlet I load my spring-context.xml

I create a Service for User
@Service("userSvc")
public class UserService {
@Autowired
private UserDAO userDAO;
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
public void create(User user){
userDAO.create(user);
}
}
And my UserDAO
@Component("userDAO")//This the id by which it will be auto wired
public class UserDAO extends BaseDAO{
public void create(User user){
try{
getSession().save(user);
}
catch(HibernateException e){
System.out.println("Error occured while saving data"+e.getMessage());
}
}
}
BaseDAO :
public class BaseDAO {
@Resource(name="sessionFactory")
protected SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
protected Session getSession(){
return sessionFactory.openSession();
}
}
And this config is working when I create a user in a main class
ApplicationContext ctx = new ClassPathXmlApplicationContext(new String[]{"spring-config.xml"});
UserService userSvc = (UserService) ctx.getBean("userSvc");
userSvc.create(user);
But when I try to create a user in my controller, I get an exception
Error occured while saving dataUnknown entity: com.manager.spring.entity.User
I really hope someone can help me, I'm not sur to have understand everything and I'm very sorry for my poor english ! Thx
