Overview

@GeneratedValue(strategy = GenerationType.AUTO)

Used together with @Id when relying on the database to automatically generate the ID value, define "strategy = AUTO".

For a PostgreSQL table in which the primary key was declared as follows:

id BIGINT UNIQUE GENERATED ALWAYS AS IDENTITY,

the corresponding annotation combination that works is:

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