Develop Reference

not-null property references a null or transient value?

i'm new in spring.I have a project that name is SampleStore. some entities created in my projects, such as User, UserRole, Product, Orders, CartItem and .... but i have a problem. when i try add new user app does it without error and new record inserted in databse. but when i try to insert new order i'll get error.

here one part of my controller code that user to save new user and save new order.
#RequestMapping(value = "/saveuser", method = RequestMethod.POST)
public ModelAndView saveNewUser(#ModelAttribute User user) {
ModelAndView model = new ModelAndView();
user.setEnabled(true);
user.setAccountNonExpired(true);
user.setAccountNonLocked(true);
user.setCredentialsNonExpired(true);
UserRole role = new UserRole(user, "ROLE_USER");
Set<UserRole> roles = new HashSet<UserRole>();
roles.add(role);
user.setUserRoles(roles);
String result = userService.addUser(user);
if (!result.toLowerCase().startsWith("error")) {
model.setViewName("loginForm");
} else {
model.setViewName("newuser");
model.addObject("error", result);
}
return model;
}
#SuppressWarnings("unchecked")
#RequestMapping(value = "/store/addorder", method = RequestMethod.GET)
public ModelAndView addOrder(HttpSession session) {
ModelAndView model = new ModelAndView();
// create list of products that we have to add in orders
System.err.println("item get to retrieving---------------");
List<CartItem> items = (List<CartItem>) session.getAttribute("cart");
for (CartItem cartItem : items) {
System.err.println(cartItem.getProduct());
}
// find user by username to set orders userinfo
System.err.println("user information get to retriving---------------");
String username = SecurityContextHolder.getContext().getAuthentication().getName();
User user = userService.findByUsername(username);
System.err.println(user);
// new order generated and setter methods invoke
System.err.println("new order generated-------------------");
Orders order = new Orders(items, user);
Date d = new Date();
Date delivery = StoreUtils.deliveryDate(d, 3);
order.setOrderDate(d);
order.setDeliveryDate(delivery);
order.setUser(user);
order.setItems(items);
String addOrders = orderService.addOrders(order);
System.err.println("new order add status " + addOrders + "-------------");
System.err.println(order);
// change product quantity after adding new order
for (int i = 0; i < items.size(); i++) {
Integer qSale = items.get(i).getQuantity() * (-1);
productService.rechargeProduct(items.get(i).getProduct(), qSale);
}
if (!addOrders.toLowerCase().contains("error")) {
model.setViewName("successorder");
model.addObject("order", order);
model.addObject("message", addOrders);
session.setAttribute("cart", null);
} else {
session.setAttribute("error", addOrders);
model.setViewName("redirect:/addtocartlist");
}
return model;
}
finally, here my code in dao class that save user and order.
UserDaoImpl.java
public String addUser(User user) {
String result = "";
String pass = encoder.encode(user.getPassword());
user.setPassword(pass);
try {
session().save(user);
session().flush();
result = "success";
} catch (Exception e) {
if (e.getCause().getMessage().toLowerCase().contains("duplicate"))
result = "error :user is already joined to store!";
else
result = "error :" + e.getCause().getMessage();
}
return result;
}
OrderDaoImpl.java
public String addOrders(Orders orders) {
String result = "";
try {
session().save(orders);
result = "success";
} catch (Exception e) {
if (e.getCause() != null)
if (e.getCause().getMessage().toLowerCase().contains("duplicate"))
result = "error this order already was exist";
else
result = "error " + e.getCause().getMessage();
else {
result = "error " + e.getMessage();
}
System.err.println(result);
} finally {
session().clear();
}
return result;
}
All codes are similar, but results are diffrent. when try to add new order I get this exception:
not-null property references a null or transient value:com.softup.store.entity.CartItem.order

Set both sides of relation. On every item call setOrder(). On user setOrder() also.

HibernateQuery returns List of Objects instead of Entities

I'm running a query via Hibernate and it´s returning a list. But the list contains objects instead of my Entities... I'm not a pro in Hibernate, but my other queries work well. I have got no idea what is my mistake right now.
List getAllUsersBasedOnMandant(Long id) {
List users = null;
try {
startOperation(false);
Query query = getSession().createQuery(" from UserEntity where mandant = '" + id + "'");
users = query.list();
} catch (HibernateException e) {
handleException(e);
} finally {
getSession().close();
}
return users;
}
My output looks like this:
[int_plan.entity.UserEntity#4b82b237, int_plan.entity.UserEntity#7141a0bb, int_plan.entity.UserEntity#65b0a12c]
My entity looks like that:

Any ideas what im doing wrong?

I hope I understood the question correctly and that my answer will help you.
Please use query.setParameter([name of parameter], [value]) it will help you with the concationation. more details on that link: https://www.mkyong.com/hibernate/hibernate-parameter-binding-examples/
Your Entitys are now Objects in the users List. you can define your List already to the Objecttype of your desire, for example List<UserEntity> users = q.getResultList()
2.a now you can adress the single elements in your list like
if(!users.isEmpty()) {
for(UserEntity uEntity : users){
uEntity.doSomething()
}
return users.get(0)}
I hope this was helpful for you

hibernate: Use of #OneToMany or #ManyToMany targeting an unmapped class

I'm using hibernate-core in a maven project and I want to create the entities for the following database: db_schema
I'm just starting to learn hibernate, so please bear with me on this one. I know that it might be a stupid mistake but I just can't figure it out.

I've been looking on Stack for a solution on similar issues but the suggestions did not help in my case. I'm kinda stuck right now.
Any help will be highly appreciated. Thank your for your time.

}
Ordersitems connects between Orders and Products - it contains the products of each order, so productId and orderId both foreign keys in Orderitems.
I think I understand the error, if I'm not wrong, the reapeted column error refers to:
#Id
#Column(name = "orderId", nullable = false, insertable = false, updatable = false)
public String getOrderId() {
return orderId;
}
and:
#ManyToOne
#JoinColumn(name = "orderId", referencedColumnName = "orderId", nullable = false)
public OrdersEntity getOrdersByOrderId() {
return ordersByOrderId;
}
public void setOrdersByOrderId(OrdersEntity ordersByOrderId) {
this.ordersByOrderId = ordersByOrderId;
}
But whatever I tried to do didn't solve the problem or even added other errors.
Can you please help me to solve this problem?
Thanks!

Saving cascade with Hibernate

I have the following entities and I'm trying to save them using hibernate cascade:
Entity Usuario:
#Entity
#Table(schema="system", name="usuarios")
public class Usuario {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private int id;
#Column(nullable = false)
private String nome;
#Column(name = "data_nascimento")
private Date dataNascimento;
private String sexo;
#OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy = "usuario")
private DadosFuncionario dadosFuncionario;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public Date getDataNascimento() {
return dataNascimento;
}
public void setDataNascimento(Date dataNascimento) {
this.dataNascimento = dataNascimento;
}
public String getSexo() {
return sexo;
}
public void setSexo(String sexo) {
this.sexo = sexo;
}
public DadosFuncionario getDadosFuncionario() {
return dadosFuncionario;
}
public void setDadosFuncionario(DadosFuncionario dadosFuncionario) {
this.dadosFuncionario = dadosFuncionario;
}
}
Table structure for usuarios:
CREATE TABLE "system"."usuarios" (
"id" int4 NOT NULL,
"data_nascimento" date,
"nome" varchar(255) COLLATE "default" NOT NULL,
"sexo" varchar(255) COLLATE "default"
)
Entity DadosFuncionario:
#Entity
#Table(schema = "system", name = "dados_funcionario")
public class DadosFuncionario {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private int id;
#Column(unique = true)
private String matricula;
#Column(name = "pref_reg", nullable = true)
private int prefReg;
#Column(name = "pref_dep", nullable = false)
private int prefDep;
#Column(nullable = true)
private String telefone;
#OneToOne
#JoinColumn(name = "id_usuario")
private Usuario usuario;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getMatricula() {
return matricula;
}
public void setMatricula(String matricula) {
this.matricula = matricula;
}
public int getPrefReg() {
return prefReg;
}
public void setPrefReg(int prefReg) {
this.prefReg = prefReg;
}
public int getPrefDep() {
return prefDep;
}
public void setPrefDep(int prefDep) {
this.prefDep = prefDep;
}
public String getTelefone() {
return telefone;
}
public void setTelefone(String telefone) {
this.telefone = telefone;
}
public Usuario getUsuario() {
return usuario;
}
public void setUsuario(Usuario usuario) {
this.usuario = usuario;
}
}
Table structure for dados_funcionario:
CREATE TABLE "system"."dados_funcionario" (
"id" int4 NOT NULL,
"matricula" varchar(255) COLLATE "default",
"pref_dep" int4 NOT NULL,
"pref_reg" int4,
"telefone" varchar(255) COLLATE "default",
"id_usuario" int4
)
And then to test if it was saving everything the way it was supposed to, I'm doing this:
Usuario novoUsuario = new Usuario();
DadosFuncionario novoDadosFuncionario = new DadosFuncionario();
novoDadosFuncionario.setMatricula("XXXXXXXXX");
novoDadosFuncionario.setPrefDep(9999);
novoUsuario.setNome("XXXXX XXXXX");
novoUsuario.setDadosFuncionario(novoDadosFuncionario);
Transaction tx = session.beginTransaction();
session.save(novoUsuario);
tx.commit();
It insert the correct data into the correct tables, but it does not save the foreign key of usuarios in dados_funcionario (its filling the column id_usuario with null). So, it understands the relationship (it saved in cascade, because I only used the session.save() with novoUsuario and it saved the data from novoDadosFuncionario) but it doesn't insert the foreign key and I can't figure out why.

You are not setting the other side of the relation anywhere, which you should in bidirectional relationships. Add this
novoDadosFuncionario.setUsuario(novoUsuario);
