Solution
By default, Hibernate generates key from hibernate_sequence table, we can disable it by setting this hibernate.use-new-id-generator-mappings to false.
application.properties
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=mkyong
spring.datasource.password=password
spring.jpa.hibernate.use-new-id-generator-mappings=false
This Solution is working
Instead of setting this property to false
spring.jpa.hibernate.use-new-id-generator-mappings=false
We can add below property then also it will work
spring.jpa.hibernate.ddl-auto=update
Yes
Thanks alot, the mentioned solution did not work for me, but your solution has worked.
Why do we get this error?
And this solution doesn’t work for me
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
CREATE TABLE model
(
id SERIAL NOT NULL,
name VARCHAR(64) NOT NULL UNIQUE,
PRIMARY KEY (id)
);
this solution works
