how to use hibernate annotations OnetoOne in springMvc? - database

Question

I'm working with spring MVC``Spring security hibernate
I've created 2 tables in the database , this the schema:
create table user(
id int(10),
name VARCHAR(30) NOT NULL,
address VARCHAR(30) NOT NULL,
PRIMARY KEY (id)
);
create table compte(
id int(10),
login VARCHAR(30) NOT NULL,
password VARCHAR(30) NOT NULL,
PRIMARY KEY (id),
FOREIGN KEY (id) REFERENCES user( id)
);
I'm developing a web application for users managements, the administrator add user's informations and submit (data from the first form is inserted into the userdatabase) and then in an other jsp he adds the authentication data for this user and submit ( here data is inserted into the second database compte )
the form in the jsp page that inserts into user's table is done correctly when it's not joined to any other table .
But when I tried to use hibernate annotations in my application and join the two tables user and compte I have errors :
Caused by: org.hibernate.AnnotationException: Unknown mappedBy in: com.package.domain.User.compte, referenced property unknown: com.package.domain.Compte.User
user.java :
#Entity
#Table(name = "user")
public class User {
#Id
#Column(name="id")
private int id;
#Column(name="name")
private String name;
#Column(name="address")
private String address;
#OneToOne(mappedBy="User", cascade=CascadeType.ALL)
private Compte compte;
//getters and setters
compte.java :
#Entity
#Table(name = "COMPTE")
public class Compte {
#Id
#GeneratedValue
#Column(name = "id")
private int id;
#Column(name = "login")
private String login;
#Column(name = "password")
private String password;
#OneToOne
#PrimaryKeyJoinColumn
private User user;
//getters and setters
I don't know how should I insert comptedata into the second table ? how it will recognize that the login and the password correspond to the user's id just inserted.
PS : i've created 2 tables in the database to use the second for authentication in spring security if my database design is incorrect please tell me :)

Firstly, you need to specify not a class name (User), but a property name (user) in the mappedBy
#OneToOne(mappedBy = "user", cascade = CascadeType.ALL)
private Compte compte;
In my opinion It will be better to associate Compte to the User by an additional foreign key and I would like to have login and password in the User table.
#Entity
#Table(name = "users")
public class User {
#Id
#GeneratedValue
#Column(name = "f_id")
private int id;
#Column(name = "f_login")
private String login;
#Column(name = "f_password")
private String password;
#OneToOne(mappedBy = "user", cascade = CascadeType.ALL)
private Compte compte;
}
#Entity
#Table(name = "comptes")
public class Compte {
#Id
#GeneratedValue
#Column(name = "f_id")
private int id;
#OneToOne
#JoinColumn(name = "fk_user")
private User user;
#Column(name = "f_name")
private String name;
}
