In-line Make it easier to specify Hibernate settings -specific configurations for sequence and table id generators .
Currently , as opposed users need to either -
# Use {{@GenericGenerator}}
# Supply a custom {{@IdGeneratorType}}
For annotations, this could either be “ Map extensions ” of to the corresponding Jakarta annotation or a “complete” annotation. E.g.,
{noformat}// an extension
public @interface TableGeneratorExtension {
String name();
// Hibernate-specific config
String optimizerName() default "";
. ..
}
E
// complete
public @interface TableGenerator {
jakarta . g persistence . TableGenerator generator();
// Hibernate-specific config
String optimizerName() default "";
...
} {noformat}
Also, in orm.xsd:
{noformat} <xsd:complexType name="sequence-generator">
<!- Standard JPA attributes -->
<xsd:attribute name="name" type="xsd:string" use="required"/>
<xsd:attribute name="sequence-name" type="xsd:string"/>
<xsd:attribute name="catalog" type="xsd:string"/>
<xsd:attribute name="schema" type="xsd:string"/>
<xsd:attribute name="initial-value" type="xsd:int"/>
<xsd:attribute name="allocation-size" type="xsd:int"/>
<!-- Extension attributes -->
<xsd:attribute name="per-entity " type="xsd:boolean"/>
<xsd:attribute name="per - entity- suffix" type="xsd:string"/>
<xsd:attribute name="optizer" type="xsd:string"/>
< xsd:attribute name="table-value-column" type="xsd:string" / >
</ xsd:complexType name="sequence-generator">{noformat}
And corresponding annotations:
{noformat}
