salut,
j'utilise myeclipse for spring pour la réalisation d'une application CRUD, le code est généré automatiquement,
le problème que j'utilise une table (test1) dont l'identifiant est auto_increment ,
comment peux_je changer le fichier TEST1.java(dont le code est le suivant) pour que puisse bénéficier de l'option auto_incrémentation
package dao.domain;

import java.io.Serializable;

import java.lang.StringBuilder;

import javax.persistence.Id;
import javax.persistence.NamedQueries;
import javax.persistence.NamedQuery;

import javax.xml.bind.annotation.*;

import javax.persistence.*;

/**
*/

@Entity
@NamedQueries({
@NamedQuery(name "findAllTest1s", query "select myTest1 from Test1 myTest1"),
@NamedQuery(name "findTest1ByIdt", query "select myTest1 from Test1 myTest1 where myTest1.idt = ?1"),
@NamedQuery(name "findTest1ByNom", query "select myTest1 from Test1 myTest1 where myTest1.nom = ?1"),
@NamedQuery(name "findTest1ByNomContaining", query "select myTest1 from Test1 myTest1 where myTest1.nom like ?1"),
@NamedQuery(name "findTest1ByPrimaryKey", query "select myTest1 from Test1 myTest1 where myTest1.idt = ?1") })
@Table(catalog "mydata", name "test1")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(namespace "runing/dao/domain", name "Test1")
public class Test1 implements Serializable {
private static final long serialVersionUID = 1L;

/**

@Column(name "idt", nullable false)
@Basic(fetch = FetchType.EAGER)
@Id
@XmlElement
Integer idt;
/**
*/

@Column(name "nom", length 200)
@Basic(fetch = FetchType.EAGER)
@XmlElement
String nom;

/**
*/

/**
*/
public Integer getIdt() {
return this.idt;
}

/**
*/
public void setNom(String nom) {
this.nom = nom;
}

/**
*/
public String getNom() {
return this.nom;
}

/**
*/
public Test1() {
}

/**
* Copies the contents of the specified bean into this bean.
*
*/
public void copy(Test1 that) {
setIdt(that.getIdt());
setNom(that.getNom());
}

/**
* Returns a textual representation of a bean.
*
*/
public String toString() {

StringBuilder buffer = new StringBuilder();

buffer.append("idt=[").append(idt).append("] ");
buffer.append("nom=[").append(nom).append("] ");

return buffer.toString();
}

/**
*/
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result (int) (prime * result + ((idt null) ? 0 : idt.hashCode()));
return result;
}

/**
*/
public boolean equals(Object obj) {
if (obj == this)
return true;
if (!(obj instanceof Test1))
return false;
Test1 equalCheck = (Test1) obj;
if ((idt == null && equalCheck.idt != null) || (idt != null && equalCheck.idt == null))
return false;
if (idt != null && !idt.equals(equalCheck.idt))
return false;
return true;
}
}
