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.

If you want to use a custom generator, you need to define the generator in a @GenericGenerator annotation and provide the fully-qualified classname as the strategy. You can also configure a set of parameters that will be provided to the configure method when Hibernate instantiates the generator.
id. new_generator_mappings that directs how identity or sequence columns are generated when using @GeneratedValue . In JBoss EAP 6, the default value for this property is set as follows: When you deploy a native Hibernate application, the default value is false .
by. The SequenceGenerator annotation defines a primary key generator that may be referenced by name when a generator element is specified for the GeneratedValue annotation. A sequence generator may be specified on the entity class or on the primary key field or property.
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")
