Foregine key is not updating in spring boot Jpa - spring

Question

Basically, I am trying to establish a relationship between my two tables using spring boots.
And the relationship which I had used was the #onetoone and #onetomany relationship.
But after building the relationship and creating the table in MySQL whenever I run the program my foreign key is not updating.
The relationship is one user can have many contacts. I have tried unidirectional as well as bidirectional mapping but it is not working.
I want in contact table there will be a separate column for the foreign key. Based on that key I will show all contacts for that particular user.
This is my contact entity...
package com.example.jpa.contactEntities;
#Entity
#Table(name = "Contact")
public class ContactEntities {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long c_id;
private String c_name;
private String second_c_name;
private String c_work;
private String c_emali;
private String c_phone;
private String c_image;
#Column(length = 5000)
private String c_description;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "contact_id")
private UserEntities userEntities;
public ContactEntities() {
super();
}
public ContactEntities(long c_id, String c_name, String second_c_name, String c_work, String c_emali,
String c_phone, String c_image, String c_description, UserEntities userEntities) {
super();
this.c_id = c_id;
this.c_name = c_name;
this.second_c_name = second_c_name;
this.c_work = c_work;
this.c_emali = c_emali;
this.c_phone = c_phone;
this.c_image = c_image;
this.c_description = c_description;
this.userEntities = userEntities;
}
public long getC_id() {
return c_id;
}
public void setC_id(int c_id) {
this.c_id = c_id;
}
public String getC_name() {
return c_name;
}
public void setC_name(String c_name) {
this.c_name = c_name;
}
public String getSecond_c_name() {
return second_c_name;
}
public void setSecond_c_name(String second_c_name) {
this.second_c_name = second_c_name;
}
public String getC_work() {
return c_work;
}
public void setC_work(String c_work) {
this.c_work = c_work;
}
public String getC_emali() {
return c_emali;
}
public void setC_emali(String c_emali) {
this.c_emali = c_emali;
}
public String getC_phone() {
return c_phone;
}
public void setC_phone(String c_phone) {
this.c_phone = c_phone;
}
public String getC_image() {
return c_image;
}
public void setC_image(String c_image) {
this.c_image = c_image;
}
public String getC_description() {
return c_description;
}
public void setC_description(String c_description) {
this.c_description = c_description;
}
public UserEntities getUserEntities() {
return userEntities;
}
public void setUserEntities(UserEntities userEntities) {
this.userEntities = userEntities;
}
#Override
public String toString() {
return "ContactEntities [c_id=" + c_id + ", c_name=" + c_name + ", second_c_name=" + second_c_name + ", c_work="

}
}
this is my user entity...
