Unable to create a table in hibernate using OneToMany and ManyToOne relationship(also unable to create Foreign Key)

Question

This code here is simply used to determine the relation of OnetoMany and ManyToOne, I use Spring Tool suite 3.9.11 with XAMPP and Server as apache 7.5

This is first file/table customer.java

package com.bean;

import java.util.List;

import javax.persistence.CascadeType;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;
import javax.persistence.Table;


@Entity
@Table(name = "Customer")
public class Customer {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int cid;

    private String cname;
    private int ccontact;
    private String cemail;
    private String cpassword;

    @OneToMany(mappedBy = "customer")
    private List<OrderF> order;

    public List<OrderF> getOrder() {
        return order;
    }

    public void setOrder(List<OrderF> order) {
        this.order = order;
    }

    public Customer() {
        super();
    }

    public int getCid() {
        return cid;
    }

    public void setCid(int cid) {
        this.cid = cid;
    }

    public String getCname() {
        return cname;
    }

    public void setCname(String cname) {
        this.cname = cname;
    }

    public int getCcontact() {
        return ccontact;
    }

    public void setCcontact(int ccontact) {
        this.ccontact = ccontact;
    }

    public String getCemail() {
        return cemail;
    }

    public void setCemail(String cemail) {
        this.cemail = cemail;
    }

    public String getCpassword() {
        return cpassword;
    }

    public void setCpassword(String cpassword) {
        this.cpassword = cpassword;
    }

}

This is my second file/table OrderF.java

package com.bean;

import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Entity
@Table(name="Order")
public class OrderF {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int food_id;
    private String foodName;
    @ManyToOne(cascade = CascadeType.PERSIST)
    @JoinColumn(name = "cid")
    private Customer customer;

    public int getFood_id() {
        return food_id;
    }

    public void setFood_id(int food_id) {
        this.food_id = food_id;
    }

    public String getFoodName() {
        return foodName;
    }

    public void setFoodName(String foodName) {
        this.foodName = foodName;
    }

public Customer getCustomer() {
    return customer;
    }

    public void setCustomer(Customer customer) {
        this.customer = customer;
    }

}

This is my main.java

package com.bean;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class MainClass {

    public static void main(String[] args) {
        Customer c=new Customer();
        c.setCid(1);
        OrderF  o=new OrderF();
        o.setCustomer(c);
        o.setFood_id(1);
        o.setFoodName("Java");
        
        SessionFactory sessionFactory=new Configuration().configure().buildSessionFactory();
        Session session=sessionFactory.openSession();
        session.beginTransaction();
        session.save(o);
        session.getTransaction().commit();
        session.close();
    }

}

This is hibernate Configuration file hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.org/dtd/hibernate-configuration-3.0.dtd">

    <mapping class="com.bean.Customer"></mapping>
    <mapping class="com.bean.OrderF"></mapping>
    </session-factory>
    

</hibernate-configuration>

Answer 1

Your Order entity's table name is a reserved word in the SQL engine, try renaming the table's name

@Entity
@Table(name="OrderF ")
public class OrderF {...}

Answer 2

As an alternative to renaming you can use SQL quoted identifiers :

@Entity
@Table(name="`Order`")
public class OrderF {
  // ...
}
