Field 'id' doesn't have a default value. AbstractPersistable problem - sql

Question

I'm crating webservice with connection to db. I have met one problem. In my User class i used AbstractPersistable to generate primary keys but it seems to have some problem with that task.
import javax.persistence.Entity;
import org.springframework.data.jpa.domain.AbstractPersistable;
#Entity
public class User extends AbstractPersistable<Long>{
private String userId;
private String userName;
private String password;
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
It throws me something like that:

It must generate primary keys but they dont have default value.
Here is my data.sql file:
use springboot;
insert into `User`(`user_id`,`user_name`,`password`) values
('user id 1', 'name 1' , 'pass1'),
('user id 2', 'name 2' , 'pass2');
And aplication properties
server.servlet.contextPath=/springboot
server.port=9090
menagement.security.enabled=false
#Hibernate
spring.datasource.data=classpath*:data.sql
spring.datasource.url=jdbc:mysql://localhost:3306/springboot
spring.datasource.username=admin
spring.datasource.password=admin
spring.datasource.initialize=true
spring.datasource.initialization-mode=always
#Jpa
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

Answer 1

The following changes worked for me:
Application.properties file:
spring.jpa.hibernate.ddl-auto=create
Entity class:
#Entity
public class User { // extends AbstractPersistable<Long>
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
..
}
