@org.hibernate.annotations.GenericGenerator allows you to define an Hibernate specific id generator.

@Id @GeneratedValue(generator="system-uuid")
@GenericGenerator(name="system-uuid", strategy = "uuid")
public String getId() {

@Id @GeneratedValue(generator="hibseq")
@GenericGenerator(name="hibseq", strategy = "seqhilo",
    parameters = {
        @Parameter(name="max_lo", value = "5"),
        @Parameter(name="sequence", value="heybabyhey")
    }
)
public Integer getId() {

strategy is the short name of an Hibernate3 generator strategy or the fully qualified class name of an IdentifierGenerator implementation. You can add some parameters through the parameters attribute.

Contrary to its standard counterpart, @GenericGenerator can be used in package level annotations, making it an application level generator (just like if it were in a JPA XML file).

@GenericGenerator(name="hibseq", strategy = "seqhilo",
    parameters = {
        @Parameter(name="max_lo", value = "5"),
        @Parameter(name="sequence", value="heybabyhey")
    }
)
