config hibernate untuk menggenerate tabel

Dalam file config hibernate { hibernate.cfg.xml } terdapat property yang digunakan untuk meng-generate table yang berasal dari object model.
Gunakan property ini untuk meng-generate table.

[sourcecode language="xml"]<property name="hibernate.hbm2ddl.auto">create</property>[/sourcecode]

Contoh model yang akan di-generate adalah Contact

[sourcecode language="java"]
package com.ipi.myweb.model;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="CONTACT")
public class Contact implements Serializable{

@Id @GeneratedValue
@Column(name="ID")
private Long id;

@Column(name="NAMA", nullable=false,length=50)
private String nama;

@Column(name="NO_HP", nullable=false, length=15)
private String no_hp;

public Long getId() {
return id;
}

public void setId(Long id) {
this.id = id;
}

public String getNama() {
return nama;
}

public void setNama(String nama) {
this.nama = nama;
}

public String getNo_hp() {
return no_hp;
}

public void setNo_hp(String no_hp) {
this.no_hp = no_hp;
}

}
