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

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; .. }
