Replace @SequenceGenerator since its deprecated

I have a problem with @SequenceGenerator:

@SequenceGenerator(name="pk_user_id", sequenceName="seq_user_id", allocationSize=1)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="pk_user_id")

When the application starts up it shows warning:

WARN 7388 --- [ main] org.hibernate.orm.deprecation : HHH90000014: Found use of deprecated [org.hibernate.id.SequenceHiLoGenerator] sequence-based id generator; use org.hibernate.id.enhanced.SequenceStyleGenerator instead. See Hibernate Domain Model Mapping Guide for details

I tried to find out how I can replace a deprecated code with a new one but can't find any solution.

In my case I had this property:

spring.jpa.hibernate.use-new-id-generator-mappings=false

A colleague had added it by mistake, and it was not needed. After removing it the warning logs were removed.

Hope this helps someone.

According to the warning message and Hibernate documentation (Hibernate deprecated list) you should use SequenceStyleGenerator. Or better use @GenericGenerator and specify generator strategy.

Here is a typical example of usage:

@GenericGenerator(
        name = "wikiSequenceGenerator",
        strategy = "org.hibernate.id.enhanced.SequenceStyleGenerator",
        parameters = {
                @Parameter(name = "sequence_name", value = "WIKI_SEQUENCE"),
                @Parameter(name = "initial_value", value = "1000"),
                @Parameter(name = "increment_size", value = "1")
        }
)
@Id
@GeneratedValue(generator = "wikiSequenceGenerator")
