How to use hibernate to map three table together

below is my three table.
I having problem mapping these three table together using #OneToMany.Not sure the right way to set up these three Entity. Thanks
Topic with many questions
Question with many answer options
CREATE TABLE `topic` (
`topic_id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(100) default null,
PRIMARY KEY (`topic_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
CREATE TABLE `question` (
`question_id` int unsigned NOT NULL AUTO_INCREMENT,
`topic_id` int unsigned NOT NULL,
`question` varchar(100) NOT NULL,
`answer` varchar(100) NOT NULL,
PRIMARY KEY (`question_id`),
KEY `topic_id` (`topic_id`),
CONSTRAINT `items_ibfk_1` FOREIGN KEY (`topic_id`) REFERENCES `topic` (`topic_id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
CREATE TABLE `option` (
`option_id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`question_id` int(11) unsigned NOT NULL,
`option` varchar(100) not null,
PRIMARY KEY (`option_id`),
KEY `question_id` (`question_id`),
CONSTRAINT `items_ibfk_2` FOREIGN KEY (`question_id`) REFERENCES `question` (`question_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

Below is the code snippet:
#Entity
class Topic
{
//other fields
#OneToMany(mappedBy="topic")
private List<Question> question;
}
#Entity
class Question
{
//other fields
#ManyToOne
#JoinColumn(name="topic_id")
private Topic topic;
#OneToMany(mappedBy="question")
private Option option;
}
#Entity
class Option
{
//other fields
#ManyToOne
#JoinColumn(name="question_id")
private Question question;
}

Below is how I set up the three entity.
But application run fail:
org.springframework.beans.factory.BeanCreationException: 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 org.hibernate.AnnotationException: Illegal attempt to map a non collection as a #OneToMany, #ManyToMany or #CollectionOfElements: com.generator.ExamMaker.entity.Question.options

How to fetch data from database using serialize object in where clause

I am storing one class as serialize object in Database in JPA.
Now I am going to fetch that data using serialize object in where clause.
Below is my serialize object class
`
public class Candidates implements Serializable{
private static final long serialVersionUID = -6852589184246588241L;
Long id;
String firstname;
String lastname;
String email;
String address;
String phone;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
}
`
And below is entity class where I'm storing serialize obejct
`
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.Lob;
import javax.persistence.ManyToOne;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;
import com.rms.vo.Candidates;
import lombok.Data;
#Entity
#Table(name = "candidate")
#Data
public class Candidate extends Auditable implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "candidate_sequence")
#SequenceGenerator(name = "candidate_sequence", sequenceName = "candidate_sequence", allocationSize = 50)
#Column(name = "candidate_id", updatable = false, nullable = false)
private Long id;
#ManyToOne
#JoinColumn(name="userId")
private User user;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
#Lob
#Column(name = "resume")
private Serializable resume;
public Candidates getResume() {
return (Candidates) resume;
}
public void setResume(Candidates resume) {
this.resume = resume;
}
}
`
and I m using below method to fetch data but its giving kindly help me to solve this issue
`
#Query("from Candidate where resume.firstname='Mujahid' or resume.firstname='MUJAHID' ")
public List<Candidate> getCandidateListByName();
'
I m getting below error

Unknown column error using hibernate OneToMany mapping

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:

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 Collection<Employee> getEmployees() {
return employees;
}
public void setEmployees(Collection<Employee> employees) {

}
}
Employee Class:
#Entity
#Table(name = "employee")
public class Employee {

Employee Dao Class:
public class EmployeeDao {

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 :

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)]

PropertyAccessException while persisting Many to Many relationship

I'm running into below exception while trying to persist Many-to-Many relationship. Any clues would be really appreciated. I'm using hibernate's #ManyToMany annotation as shown below.
If I remove houses from the construction entity and then persist it works ok. The problem occurs only when I say construction.setHouses(houses) before calling persist. And I have 3 tables: Construction, House, and Construction_houses. Where Construction_houses stores mapping between construction and house using their primary keys.
#ManyToMany(cascade = CascadeType.ALL)
#JoinTable(name="construction_houses",
joinColumns={#JoinColumn(name="construction_id", referencedColumnName = "id")},
inverseJoinColumns={#JoinColumn(name="house_id", referencedColumnName = "id")})
private List<House> houses = new ArrayList<>();
Exception:
org.hibernate.PropertyAccessException: could not get a field value by reflection getter of com.construction.domain.House.id

The stacktrace states:
Can not set java.lang.Long field com.construction.domain.House.id to [Ljava.lang.Object;
Unfortunately that message is not only given for setters, but for getters as well.
So the message tells you that it tries to read the field House.id not for an object of type House, but for an object of type Object[].
It seems that your houses is not a list of House objects, but of arrays - or it contains at least one such array.
If you call System.out.println(construction.getHouses()); right before you persist your construction you will find something like: ...[Ljava.lang.Object;#...
