How can i fix org.hibernate.PersistentObjectException error?

I am trying to connect MySQL Database and insert a new user to the the database.My DB name is bookstoredb and the table name is users.I tried to create model class using hibernate and jpa but i am getting PersistentObjectException error.What am i doing wrong?

entityManager.getTransaction().begin();
entityManager.persist(user1);

System.out.println("Successfully inserted");
}
}
My packages:

You have defined fullName to be your unique key of Users, but at the same time use a #GeneratedValue(strategy=GenerationType.IDENTITY). In your test you manually set this value and thus persist fails. The persist operation (as the name suggests) is intended for brand new objects with no id set, but since you set your fullName you are bascially trying to persist a detached entity.

I edited users table in bookstoredb like this:
And i fixed my POJO class like this:
package com.bookstore.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
#Entity
public class Users {
private Integer userId;
private String email;
private String fullName;
private String password;
#Column(name="user_id")
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
#Column(name="full_name")
public String getFullName() {
return fullName;
}
public void setFullName(String fullName) {
this.fullName = fullName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}

Hibernate is adding class name before column name automatically generating Foreign key exception

I am a beginner in Hibernate. I have two tables, "Cities" and "States". My City class is the following:
package model;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.UniqueConstraint;
import javax.persistence.Version;
#Entity
#Table(name="Cities",uniqueConstraints= {#UniqueConstraint(columnNames= {"city_id"})})
public class Cities {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private int city_id;
#Column(name="CITY_NAME",nullable=true,unique=false)
private String city_name;
#Column(name="POPULATION",nullable=true,unique=false)
private int population;
#Column(name="TS_CNT",nullable=false,unique=true)
#Version
private int ts_cnt;
public int getCity_id() {
return city_id;
}
public void setCity_id(int city_id) {
this.city_id = city_id;
}
public String getCity_name() {
return city_name;
}
public void setCity_name(String city_name) {
this.city_name = city_name;
}
public int getPopulation() {
return population;
}
public void setPopulation(int population) {
this.population = population;
}
public int getTs_cnt() {
return ts_cnt;
}
public void setTs_cnt(int ts_cnt) {
this.ts_cnt = ts_cnt;
}
}
And following is my "State" class.
package model;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToOne;
import javax.persistence.Table;
#Entity
#Table
public class State {
#Id
#Column(name = "state_id", nullable = false, unique = true)
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int state_id;
#Column(name = "state_name", nullable = false, unique = true)
private String state_name;
#Column(name = "state_capital", nullable = false, unique = true)
private String state_capital;
#OneToOne
private Cities cities;
public int getState_id() {
return state_id;
}
public void setState_id(int state_id) {
this.state_id = state_id;
}
public String getState_name() {
return state_name;
}
public void setState_name(String state_name) {
this.state_name = state_name;
}
public String getState_capital() {
return state_capital;
}
public void setState_capital(String state_capital) {
this.state_capital = state_capital;
}
public Cities getCities() {
return cities;
}
public void setCities(Cities cities) {
this.cities = cities;
}
}
Now when I run this code, like the following, I get exception:
package citiutilities;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import interfaces.Dbops;
import model.Cities;
import model.State;
public class InsertCities implements Dbops {
public static void main(String[] args) {
Cities citi1 = new Cities();
State state1 = new State();
InsertCities ic = new InsertCities();
ic.insertCities(citi1, state1);
}
public void insertCities(Cities citi1, State state1) {
citi1.setCity_id(100);
citi1.setCity_name("Patna");
citi1.setPopulation(180000);
state1.setState_id(100);
state1.setState_capital("Patna");
state1.setState_name("Bihar");
state1.setCities(citi1);
Session session = CityDbUtil.createSession();
session.beginTransaction();
try {
session.save(state1);
session.getTransaction().commit();
System.out.println("The city that was saved is :: " + citi1.getCity_id());
} catch (HibernateException he) {
session.getTransaction().rollback();
he.printStackTrace();
}
finally {
session.close();
}
}
}

What I observed in this particular case is that, somehow system is creating a column Cities_city_id in the state table whereas the intention was that system creates a column with the name city_id. According to me this is creating the problem because this column does not exist in the cities table. But I do not understand why system is manipulating the name. I tried to search in internet but in vain.

Observed 2 issues while running the code
state1.setState_id(100);
citi1.setCity_id(100);
These two fields has already #GeneratedValue Tag , meaning no need to explicitly set it.
Secondly, Once i resolved the above , the second error is
object references an unsaved transient instance - save the transient instance before flushing
For this, update the State.java. Adding CascadeType.ALL helps save the City Information while saving State Info.
#OneToOne(cascade =CascadeType.ALL)
private Cities cities;
Regarding the Cities_city_id , thats the foreign key
FOREIGN KEY (`cities_city_id`) REFERENCES `Cities` (`city_id`)

Sequence does not exist exception while using Generation annotation in Hibernate

Please see my Model class:
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="STUDENT")
public class Student {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="student_id")
private String studentId;
#Column(name="student_name")
private String studentName;
public String getStudentId() {
return studentId;
}
public void setStudentId(String studentId) {
this.studentId = studentId;
}
public String getStudentName() {
return studentName;
}
public void setStudentName(String studentName) {
this.studentName = studentName;
}
}
and save it to DB like below:
public static void test4()
{
Student st = new Student();
st.setStudentName("Bitt");
SessionFactory sessionF = new Configuration().configure().buildSessionFactory();
Session session = sessionF.openSession();
session.beginTransaction();
session.save(st);
st = new Student();
st.setStudentName("Rock");
session.save(st);
session.getTransaction().commit();
session.close();
}
the background DB is Oracle11g, Hibernate version is hibernate-core-5.2.10.Final.jar.
from my opinion, if studentId is String data type, hibernate should generate a random string, if studentId is int data type, hibernate should generate a unique number to make sure it is not duplicate in DB, but I got following error message:

so, how can I have hibernate to generate the primary key value automatically for me?

Please change your code to this and check once,
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="student_id")
private Integer studentId;
#GeneratedValue(strategy = GenerationType.AUTO)
This gives you a numeric long value which is auto updated for studentId, each and every record you add.

JavaFX desktop app - Using HSQLDB (embedded) and Hibernate

Is there good tutorial on using HSQLDB, Hibernate and JavaFX. I am using eclipse as my IDE. My Project model has variables defined like this:
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "PROJECTID")
private long projectId;
#Column(name = "PROJECTNAME")
private final StringProperty projectName;
#Column(name = "PROJECTJIBP")
private final StringProperty projectJIBP;
Is this valid way of using Hibernate with JavaFX ?

Is this valid way of using Hibernate with JavaFX ?
No: use property access instead of field access:
private final StringProperty projectName;
#Column(name = "PROJECTNAME")
public final String getProjectName() {
return projectName.get();
}
public final void setProjectName(String projectName) {
this.projectName.set(projectName);
}
public StringProperty projectNameProperty() {
return projectName;
}
etc...
This enables Hibernate to determine the types from the return types of the get methods, rather than from the types of the actual fields; so it can persist Strings instead of StringPropertys, and so on.

Hibernate mapping exception: unknown entity

I am new to Java and just started learning Hibernate from an online tutorial. I have created java code with Hibernate but after that i have been failing to test run.
I have database table "users" in MySQL Database "test". when i try to insert a record it gives me this error. Cant find the exact reason..
