I m new to hibernate and having error Unknown column in OneToMany mapping. I m trying to implement the one to many relationships using hibernate but having an error.
Here is my Code:
Department Class:
#Entity
#Table(name="department")
public class Department {
#Id
#Column(name="dept_id")
private int id;
#Column(name="dept_name")
private String name;
#OneToMany(mappedBy="department", cascade=CascadeType.ALL, fetch=FetchType.EAGER)
private Collection<Employee> employees = new ArrayList<Employee>();
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Collection<Employee> getEmployees() {
return employees;
}
public void setEmployees(Collection<Employee> employees) {
this.employees = employees;
}
}
Employee Class:
#Entity
#Table(name = "employee")
public class Employee {
#Column(name="emp_id")
#Id
private int id;
#Column(name="emp_name")
private String name;
#ManyToOne
private Department department;
public Department getDepartment() {
return department;
}
public void setDepartment(Department department) {
this.department = department;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Employee Dao Class:
public class EmployeeDao {
public void addEmployee(Employee emp, int id){
Department department = new Department();
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
department = (Department) session.get(Department.class, id);
emp.setDepartment(department);
department.getEmployees().add(emp);
session.save(emp);
session.getTransaction().commit();
session.close();
sessionFactory.close();
}
}
Here is my Database :
CREATE TABLE `department` (
`dept_id` int(11) NOT NULL,
`dept_name` varchar(255) DEFAULT NULL
)
CREATE TABLE `employee` (
`emp_id` int(11) NOT NULL,
`emp_name` varchar(255) DEFAULT NULL,
`dept_id` int(11) DEFAULT NULL
)

Can you please tell me what I'm doing wrong here? :)
Try make so
#ManyToOne
#JoinColumn(name = "dept_id")
private Department department;
The default column name for mapping is of type,
table_name + '_' + target_table_primary_key. This is why it is looking for department_dept_id
You can specify mapping column using annotations. #JoinColumn(name="dept_id").
Property-based access is the right way for using #OneToMany and #ManyToOne annotation
Use #OneToMany like below:
private Collection<Employee> employees;
#OneToMany(mappedBy="department", cascade=CascadeType.ALL, fetch=FetchType.EAGER)
public Collection<Employee> getEmployees() {
return employees;
}
public void setEmployees(Collection<Employee> employees) {
this.employees = employees;
}
And use #ManyToOne like below:
private Department department;
#ManyToOne
#JoinColumn(name = "dept_id")
public Department getDepartment() {
return department;
}
public void setDepartment(Department department) {
this.department = department;
}
Also you need to use an empty constructor in your model classes, as hibernate wants it.
If you use #OnetoMany and #ManyToOne with File-based access then you will get the following error
Initial SessionFactory creation failed.org.hibernate.MappingException: Could not determine type for: java.util.List, for columns: [org.hibernate.mapping.Column(relatedResources)]

My web application was working until I decided to put in comments. I messed it up a lot so I changed spring.jpa.hibernate.ddl-auto from upate to create-drop
But now, when I spring.jpa.hibernate.ddl-auto = create-drop the application starts and when I change it to spring.jpa.hibernate.ddl-auto = update I get this error:

And then I have a repository for the appropriate Entities. I have heavily edited the code so I won't be a "heresallmycode" guy. But, I'm pretty sure that my annotation relations are the problem. I wanted there to be comments that have a MANY TO ONE relationship with an article, a user that would appear above the comments when they are posted and a reverse ONE TO MANY relationship of the article with the comments. When the tables are created using the create paramater, my articles table was not emptied(I had it on update before), I had to manually drop it. Now, when the table is created it's empty. I thought that was worth mentioning. I can post the create logs If that would be neccessary.
EDIT
I forgot my ArticleController
#Controller

You have defined the relation to User in Comment as:
#ManyToOne()
#JoinColumn(nullable = false, name = "commenterId")
public User getCommenter()
{
return commenter;
}
but you are referring to comments string column on the Comment side of the relationship. You should change the mappedBy to:
#OneToMany(mappedBy = "commenter")
public Set<Comment> getComments()
{
return comments;
}
What is wrong: I'm trying to implement login using Spring Security. I'm using Spring Security's default endpoint login. I keep receiving 500s and I believe it's due to incorrect joint because when I'm printing
public Set<Role> getRoles() {
System.out.println("roles");
System.out.println(roles);
return roles;
}
roles is null. 'll show my stack trace at the end of the question.
What I want to have: correct working join.
My code
Join:
#OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
#JoinTable(
name = "userrole",
joinColumns = #JoinColumn(name = "iduser"),
inverseJoinColumns = #JoinColumn(name = "roleid"))
private Set<Role> roles;

How I create database:
CREATE TABLE Role (
roleId INTEGER NOT NULL,
role VARCHAR NOT NULL,
CONSTRAINT pkrole PRIMARY KEY (roleId)
);
CREATE SEQUENCE user_1_iduser_seq;
CREATE TABLE User_1 (
idUser INTEGER NOT NULL DEFAULT nextval('user_1_iduser_seq'),
id_points INTEGER NOT NULL,
userName VARCHAR NOT NULL,
isBlocked BOOLEAN DEFAULT False NOT NULL,
email VARCHAR NOT NULL,
lastName VARCHAR NOT NULL,
firstName VARCHAR NOT NULL,
password VARCHAR NOT NULL,
token VARCHAR,
CONSTRAINT pkuser PRIMARY KEY (idUser)
);
ALTER SEQUENCE user_1_iduser_seq OWNED BY User_1.idUser;
CREATE TABLE userRole (
idUser INTEGER NOT NULL,
roleId INTEGER NOT NULL
);
ALTER TABLE userRole ADD CONSTRAINT role_userrole_fk
FOREIGN KEY (roleId)
REFERENCES Role (roleId)
ON DELETE NO ACTION
ON UPDATE NO ACTION
NOT DEFERRABLE;
ALTER TABLE User_1 ADD CONSTRAINT points_us_fk
FOREIGN KEY (id_points)
REFERENCES Points (idPoints)
ON DELETE CASCADE
ON UPDATE CASCADE
NOT DEFERRABLE;
ALTER TABLE userRole ADD CONSTRAINT user_1_userrole_fk
FOREIGN KEY (idUser)
REFERENCES User_1 (idUser)
ON DELETE NO ACTION
ON UPDATE NO ACTION
NOT DEFERRABLE;
How I populate databse with data:
INSERT INTO Role VALUES(1, 'ADMIN');
INSERT INTO Role VALUES(2, 'USER');
INSERT INTO Publisher VALUES(1, 'Zielona Sowa');
INSERT INTO Category VALUES(1,'kryminal');
INSERT INTO Points VALUES(1,20);
INSERT INTO Author VALUES(1, 'Tolkien', 'John Ronald Reuel');
INSERT INTO User_1 VALUES(1,1,'oliwka',false,'oliwka#wp.pl','m','o','jakies');
INSERT INTO userRole VALUES(1,1);
INSERT INTO Book VALUES(1,1,1,'Hobbit',null,3,false,1937);
INSERT INTO BooksByAuthors VALUES(1,1,1);
INSERT INTO BooksByCategory VALUES(1,1,1);

The association between User and Role is Many-to-Many and not One-to-many.
Change your mappings like so in the User entity
#ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
#JoinTable(
joinColumns = #JoinColumn(name = "iduser"),
inverseJoinColumns = #JoinColumn(name = "roleid")
)
private Set<Role> roles;

ps is an alias. You should specify a property name of PlayerSuspension. For an example ps.name.
You can use something like this (you can convert it to criteria). Maybe, it can be more simply
from TeamPlayer teamPlayer
left join teamPlayer.player player
left join player.playerSuspensions suspension
where suspension.team.id = :teamId
or not exists (select innerTeamPlayer.id from TeamPlayer innerTeamPlayer
inner join innerTeamPlayer.player innerPlayer
inner join innerPlayer.playerSuspensions
where innerTeamPlayer.id = teamPlayer.id)
Update
You can't use TeamPlayer.getPlayerSuspension() with result of this HQL. Because of collections are lazy by default. You can try to fetch playerSuspensions by HQL with left join fetch
from TeamPlayer teamPlayer
left join teamPlayer.player player
left join fetch player.playerSuspensions suspension
where suspension.team.id = :teamId
or not exists (select innerTeamPlayer.id from TeamPlayer innerTeamPlayer
inner join innerTeamPlayer.player innerPlayer
inner join innerPlayer.playerSuspensions
where innerTeamPlayer.id = teamPlayer.id)
or you can change a mapping
#OneToMany(fetch = FetchType.EAGER, mappedBy = "player")
private List<PlayerSuspension> playerSuspensions;
Am new to JPA. Building the select query with the where clause. I need to select from table Contacts all ContactName's that equals the value of the String name.
Used the code below to create DB table:
CREATE TABLE Contacts (
ContactId BIGINT UNSIGNED NOT NULL PRIMARY KEY AUTO_INCREMENT,
ContactName VARCHAR(100) NOT NULL,
ContactEmailID VARCHAR(100) NOT NULL,
UserName VARCHAR(100) NOT NULL,
INDEX Contact_Names (ContactName)
) ENGINE = InnoDB;
Following is my Entity class;
#Entity
private String UserName;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "ContactId")
public long getContactId() {
return ContactId;
}
public void setContactId(long contactId) {
ContactId = contactId;
}
#Basic
#Column(name = "UserName")
public String getUserName() {
return UserName;
}
public void setUserName(String UserName) {
this.UserName = UserName;
}
Following is my ContactServlet class code where i am trying to write my CriteriaBuilder code.
EntityManager manager = null;
EntityTransaction transaction = null;
try{
manager = this.factory.createEntityManager();
transaction = manager.getTransaction();
transaction.begin();
CriteriaBuilder cb = manager.getCriteriaBuilder();
CriteriaQuery<Contact> q1 = cb.createQuery(Contact.class);
Root<Contact> postRoot = q1.from(Contact.class);
q1.select(postRoot).where(cb.equal(postRoot.get("UserName"), name));
TypedQuery<Contact> qry = manager.createQuery(q1);
List<Contact> result = qry.getResultList();
for (Contact contactInstance : result)
{
DBContactName = contactInstance.getContactName().trim();
DBContactEmail = contactInstance.getContactEmailID().trim();
.....
Don't know where am i going wrong??

Try with:
q1.select(postRoot).where(cb.equal(postRoot.get("userName"), name));
The u of UserName attribute in lower case.

How I can persist with JPAContainer these 2 entities ?
This is Hibernate 101.
For proof-of-concept this is easy. You're best bet is to use Spring transaction + hibernate + dao model
