Hi write Spring application, using Spring Security. It's my database for user and account role:
create table users (
id int not null primary key,
username varchar2(20) not null unique,
password varchar2(20) not null,
firstName varchar2(20),
lastName varchar2(20),
personalId varchar2(11) unique,
city varchar2(40),
address varchar2(40),
email varchar2(30) unique,
phone varchar2(9) unique,
enabled number(1) not null
);
create table user_roles (
id int primary key,
name varchar2(20) not null,
username varchar(20) constraint username_fk references users(username) not null
);
My Entity classes:
#Entity
#Table(name = "users")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue
#Column(name = "id")
private Integer id;
#NotNull
#Column(name = "username")
private String username;
#NotNull
#Column(name = "password")
private String password;
#Column(name = "firstName")
private String firstName;
#Column(name = "lastName")
private String lastName;
#Column(name = "personalId")
private String personalId;
#Column(name = "city")
private String city;
#Column(name = "address")
private String address;
#Column(name = "email")
private String email;
#Column(name = "phone")
private String phone;
#NotNull
#Column(name = "enabled")
private int enabled;
#OneToMany(mappedBy = "username")
private Set<UserRole> userRoleSet = new HashSet<UserRole>(0);
#Entity
#Table(name = "user_roles")

When I try login in my system i have error:

I think so, my mapped foregin key for tables is bad. Example query from Userreturn users from table, but when i try get user_roles i have above error. Please check correctness my mapped. I using Oracle database and Hiberante.
The problem is, that when you're mapping entities Hibernate expects the foreign key to be the id of the referenced entity, i.e. you should map on user-id instead of username.
Also your entity mapping seems to be wrong: you use a ManyToOne with the target entity being User but the type of the property is String. AFAIK Hibernate would try to assign the user to username, which should fail miserably.
So the table should look like this:
create table user_roles (
id int primary key,
name varchar2(20) not null,
userid int constraint userid_fk references users(id) not null
);
And the mapping in UserRole should then be:
#JoinColumn(name = "userid")
#ManyToOne
private User user;
Plus the reverse mapping in User:
#OneToMany(mappedBy = "user")
private Set<UserRole> userRoleSet;
As a side note, please keep in mind that id is a special keyword in HQL, i.e. it will always reference an entity's id. If id always is the only property annotated with #Id then it's no problem, but if you change that you can run into problems with queries selecting the wrong data or even failing.

I have two tables:
CREATE TABLE users
(
id INTEGER PRIMARY KEY AUTO_INCREMENT,
username VARCHAR(50) NOT NULL UNIQUE,
password VARCHAR(68) NOT NULL,
oldPassword VARCHAR(68),
enabled BOOLEAN NOT NULL
);
and
CREATE TABLE authorities (
id INTEGER PRIMARY KEY AUTO_INCREMENT,
username VARCHAR(50) NOT NULL,
authority VARCHAR(50) NOT NULL,
FOREIGN KEY (username) REFERENCES users(username)
);
CREATE UNIQUE INDEX ix_auth_username on authorities (username,authority);
Unfortunatelly instead of joining with authority_id which should be in users table I just have username which is the same in both tables.
In models I tried (ommited getters and setters):
#Entity(name = "users")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String username;
private String password;
private String oldPassword;
private boolean enabled;
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "username", referencedColumnName = "username")
private Authorities authority;
}
and
#Entity
public class Authorities {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String username;
private String authority;
#OneToOne(mappedBy = "authority")
private User user;
}
but then I have an error: Repeated column in mapping for entity column: username (should be mapped with insert="false" update="false")
The reason you are getting usernames in both tables is that you have declared username column in both the tables.
Also, you have to map the relation based on the authority_id so the code of the models would look like this:
#Entity(name = "users")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String username;
private String password;
private String oldPassword;
private boolean enabled;
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "authority_id", referencedColumnName = "id")
private Authorities authority;
}
#Entity
public class Authorities {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String authority;
#OneToOne(mappedBy = "authority")
private User user;
}
And the tables will be created like this:
Hope this solves your problem.
The message is clear: you have a repeated column in the mapping, and a column "username" in both tables has repeated. Instead of this, you should use this :
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "authority_username", referencedColumnName = "username")
private Authorities authority;
I have two Entity classes User and UserProfile. The User table has a primary key for the User ID which is a long data type. This User ID is supposed to be the primary key in user_profile as well. User also has email as a column, which I want to be linked to the user_profile also. The issue I am having is that for some reason, a column named id is being inserted into my table when I already have the primary key user_id set in the user_profile table. Does anyone know what I am doing wrong?

You can avoid the usage of SecondaryTable and use just OneToOne and mappedBy and #PrimaryKeyJoinColumn :

public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "user_id")

public class UserProfile {

#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "user_id")

#OneToOne
#PrimaryKeyJoinColumn(name = "user_id")
User user;
// other fields
// getters and setters

I was not aware of #MapsId, learned something new.
A simple search and found following
can someone please explain me #MapsId in hibernate?
I tried with dummy code. It looks like we are mixing #SecondaryTable and #MapsId together.
The duplicate column is from SecondaryTable annotation.
i don't have full context of requirement here, mostly https://www.baeldung.com/jpa-mapping-single-entity-to-multiple-tables should solve the need. #Oussama ZAGHDOUD also mentioned this in his response.
In summary, use #MapsId when you want to keep two separate entity class for 2 tables and #SecondaryTable combines 2 tables into one entity class. Both acts same way, primary key of one table works as primary key and foreign key of 2nd table.
With #MapsId only I was getting following sql
Hibernate: create table user_profile (profile_banner varchar(255), profile_img varchar(255), user_user_id bigint not null, primary key (user_user_id))
Hibernate: create table users (user_id bigint generated by default as identity, email varchar(50), password varchar(120), username varchar(20), primary key (user_id))
Hibernate: alter table users add constraint UKr43af9ap4edm43mmtq01oddj6 unique (username)
Hibernate: alter table user_profile add constraint FKqkgvrni6161p23yj2lbp9xxlk foreign key (user_user_id) references users
With #SecondaryTable
Hibernate: create table user_profile (email varchar(50), profile_banner varchar(255), profile_img varchar(255), user_id bigint not null, primary key (user_id))
Hibernate: create table users (user_id bigint generated by default as identity, password varchar(120), username varchar(20), primary key (user_id))
Hibernate: alter table users add constraint UKr43af9ap4edm43mmtq01oddj6 unique (username)
Hibernate: alter table user_profile add constraint FKuganfwvnbll4kn2a3jeyxtyi foreign key (user_id) references users

I'm trying to relate two tables
User and Address
A user has a single address, an address belongs to only one user. Keys are listed by the ID of an Address
so I create my address first and then I create a user and link it with an address id
But I can't do it at all, I have the following error in return:
Error creating bean with name 'entityManagerFactory' defined in class path resource [org / springframework / boot / autoconfigure / orm / jpa / HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NullPointerException: Cannot invoke "org.hibernate.mapping.PersistentClass.getTable ()" because "classMapping" is null
i'm totally new to hibernate but i need this project for college so forgive me for the ignorance on the subject

And thats my Logic Model
EDIT
I tried to delete the "mapped by" part and remove the #OneToOne from Address but now it returns the following error when I try to send an POST of Adress:
org.h2.jdbc.JdbcSQLIntegrityConstraintViolationException: Referential integrity constraint violation: "FKMXNOON0IKGA83W1A203Y6OFPN: PUBLIC.ENDERECO FOREIGN KEY(ID) REFERENCES PUBLIC.USUARIO(ID) (1)"; SQL statement:
insert into endereco (bairro, cep, cidade, complemento, logradouro, numero_logradouro, uf, id) values (?, ?, ?, ?, ?, ?, ?, ?) [23506-200]
as if he didn’t enter any Address fields
Im sending my POST by Postman like this:
{
"bairro": "Vila Prmavera",
"cep": "03388110",
"cidade": "São Paulo",
"complemento": "b1",
"logradouro": "Rua das dores",
"numeroLogradouro": 7,
"uf": "SP"
}
Don't map on the Id. Map means entity mapping not id mapping.
public class Endereco {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
#OneToOne
private Usuario usuario
....
}
Or if you don't want Endereco to hold a reference to a Usuario just remove it. But you can't place #OneToOne on the id field. If you have only on one side the #OneToOne then you need also the annotation #MapsId.
public class Usario {
#NotNull
#MapsId
#OneToOne(cascade = CascadeType.ALL)
private Endereco endereco;
public class Endereco {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer id
}
Because #OneToOne tries to Map with an entity which means to a table in Database. For id there isn't any entity or Table in the database. That is why it complains
I have a users table which contains the user details. i also have a authorities table which has the role of a user. The user and authorities table has one to many mapping. When i try to save the details using Jpa the foreign key column is blank no data is inserted in that field. i have a form in which i am specifying the role of the user along with other details.

When i try to save the user details it doesn't insert any value in the foreign key column. Can someone tell me what i am doing wrong.
You need to setusers field in Authorities manually. Hibernate won't fill it for you.
I am new to Hibernate, so please forgive me if the question is duplicated or stupid. I am using Hibernate 3.3.0, PostgreSQL DB. Right now I have 2 entities. I need to associate them with #OneToMany annotation in such way, that User.roleID was PK and Role.id was FK (user can have only one role, and the same role can be assigned to many users). Also as I was searching Google, I found out that for some reason every example with annotation associations has the annotated field declared as Set. Please, explain this to me. Thank you in advice.
