java - Hibernate wrong generate auto id increment -


i not sure happened 1 day hibernate started wrong generate auto id in osoba.

what mean when add person(osoba) gets id 60, next 1 gets 64 should 61... how can fix that? increment 1 no 4 or other now... how can "reset" id value? clean whole table, , start counting id 1

<class name="osoba" table="daneosobowe">          <id name="id" type="int" column="id">                 <generator class="native"/>                 </id> 
public class osoba implements interface {      private int id;     private string imie;     private string nazwisko;     private string email;     private string telefon;     private string uczelnia;     private string doswiadczenie;         private string skadslyszal;     private list zainteresowania = new arraylist();     public osoba(){ // domyslny       }    // konstruktor zeby mozna bylo sobie w jednej linijce dodawac osobe    public osoba(string imie1, string nazwisko1, string telefon1, string email1, string uczelnia1, string doswiadczenie1, string skadslyszal1 ){        this.imie = imie1;        this.nazwisko = nazwisko1;        this.email = email1;        this.telefon = telefon1;        this.uczelnia = uczelnia1;        this.doswiadczenie = doswiadczenie1;        this.skadslyszal = skadslyszal1;        }

using annotations -

@id @generatedvalue(strategy=generationtype.sequence, generator="course_seq") @sequencegenerator(     name="course_seq",     sequencename="course_sequence",     allocationsize=1 ) private int id;

allocation size of 1 increment 1.
