Sequence “HIBERNATE_SEQUENCE” not found; SQL statement

Update your code as below:

 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 private Long id;

As you have not specified a sequence table name, hibernate will look for a sequence table named as hibernate_sequence and use it as default.

For Oracle/Postgres, increment fields used are sequence tables.
In MySql, there are increment fields that automatically increment.
