problème en utilisant referencedColumnName

Bonjour,

j'essaie de suivre un exemple d'un bouquin, pour faire un @ManyToOne en utilisant une table de jointure:

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
29
30
31
32
33
34
35
36
37
38
39
40
41
42
43
44
45
46
47
48
49
50
 
@Entity
@IdClass(Account.AccountPk.class)
public class Account {
private String description;
private String code;
private Integer number;
private Customer customer;
public Account(String description) {
this.description = description;
}
protected Account() {
}
@Id
public String getCode() {
return this.code;
}
@Id
public Integer getNumber() {
return this.number;
}
public String getDescription() {
return this.description;
}
 
@ManyToOne 
@JoinTable(name="acount_customer",
        joinColumns={
            @JoinColumn(name="code_costomer", referencedColumnName="code"),
            @JoinColumn(name="number")
},
        inverseJoinColumns=@JoinColumn(name="id"))
public Customer getCustomer() {
     return customer;
}
 
public void setDescription(String description) {
this.description = description;
}
public void setNumber(Integer number) {
this.number = number;
}
public void setCode(String code) {
this.code = code;
}
 
public static class AccountPk {
// ...
}
}

j'utilise hibernate comme provider avec:

Code:

1
2
 
<property name="hibernate.hbm2ddl.auto">update</ property>

le problème est que en lançant le test unitaire j'ai l'exception:

Code:

1
