@javax.persistence.SequenceGenerator defaults to 'seqhilo' strategy. -------------------------------------------------------------------- Key: ANN-354 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-354 Project: Hibernate Annotations Issue Type: Improvement Affects Versions: 3.2.0.cr1 Reporter: Andrey Petrov When using an oracle-style sequence to auto generate primary key values like this: @Id @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="MySeq") @SequenceGenerator(name="MySeq", sequenceName="ORACLE_SEQ") public long getId() { return id; } then a org.hibernate.id.SequenceHiLoGenerator is always used. There should be a way to configure a different generator! Since the hilo generator is not suitable for my application I have to use this instead: @Id @GeneratedValue(generator="MySeq") @GenericGenerator( //this is a hibernate-specific hack to force the use of a regular sequence generator //otherwise a sequencehilo generator is used by default :-((( name = "MySeq", strategy = "sequence", parameters = { @Parameter(name = "sequence", value = "ORACLE_SEQ") } ) public long getId() { return id; } Now this works fine and while this solution can be tolerated for my app I really wish there was another way to control the default generator strategy (sequencehilo or plain sequence) without resorting to hibernate-specific org.hibernate.annotations.GenericGenerator annotations. Do you think a mechanism for configuring that can be added to a future hibernate annotations version? p.s. as long as i can see the seqhilo generation strategy is hardcoded in: org.hibernate.cfg.AnnotationBinder.java:1925: case SEQUENCE: org.hibernate.cfg.AnnotationBinder.java:1926: return "seqhilo"; (in hibernate annotations version 3.2.0.cr1)
