How to Create Hibernate Project?

Posted on by coder

1- Create a netbeans JAVA project.

2- Add Library   “Hibernate JPA ”

3- Right click project   >  Create new  Hibernate Config > Hibernate.cfg

Write Connection parameters then test your  Connection.

Connection Properties,   Then create “Hibernate…cfg”

This hibernate configuration file location usually located at the root directory.

 

For example

”    javakLibsrcHibernate.cfg”

 

4- We need to create  .Class  for the Fields of the  database.Table.

There are 2 options

First :  is  set the fields by XML file

Second : is set the fields properties inside of java file.  Which method name is Annotation

 

Example .java Class for the Fields

package hibernate;


import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Table;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.UniqueConstraint;
@Entity
@Table(name="tmp_hibernate",uniqueConstraints={@UniqueConstraint(columnNames={"id"})})
public class customer implements Serializable {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="id", nullable=false, unique=true, length=11)
    private Integer id;
    
    @Column(name="bayi_kodu", length=20, nullable=true)
    private int bayi_kodu;
    
    @Column(name="email", length=20, nullable=true)
    private String email;
    
    @Column(name="uname", length=20, nullable=true)
    private String username;

    
    public int getid() {
        return this.id;
    }
    public void setid(int id) {
        this.id = id;
    }

With this annotation file  we need to  set  location of  this file as a mapping inside of  Hibernate |Config .

Package name is   hibernate

Class name is   customer

 




  
    org.hibernate.dialect.MySQLDialect
    com.mysql.jdbc.Driver
    jdbc:mysql://xxxxxx:3306/DatabaseNAME?zeroDateTimeBehavior=convertToNull
    USERNAME
    PASSWORD
    
         
        
        thread

If you are not using annotation  method,  you need to define Field types inside of .xml file then you need to give xml path to   Hibernate.cfg file

BuildSessionFactory

 

Example   Util.java  for  hibernate

package hibernate;

import java.util.Properties;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;

public class util {

    private static SessionFactory sessionFactory = buildSessionFactory();

    /**
     * @return 
     */
    private static SessionFactory buildSessionAnnotationFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            Configuration configuration = new Configuration();
            configuration.configure("hibernate.cfg.xml");
            System.out.println("Hibernate Annotation Configuration loaded");

            ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
            System.out.println("Hibernate Annotation serviceRegistry created");

            SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

            return sessionFactory;
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    private static SessionFactory sessionAnnotationFactory;
    public static SessionFactory getSessionAnnotationFactory() {
        if(sessionAnnotationFactory == null) sessionAnnotationFactory = buildSessionAnnotationFactory();
        return sessionAnnotationFactory;
    }
    
    public static void shutdown() {
        // Close caches and connection pools
        sessionFactory.close();
    }
    public static SessionFactory getSessionFactory() {
        if(sessionFactory == null) sessionFactory = buildSessionFactory();
        return sessionFactory;
    }

}

 

5- Testing,

import hibernate.customer;
import hibernate.util;
import org.hibernate.Session;
import net.sf.ehcache.hibernate.HibernateUtil;
import org.hibernate.SessionFactory;

hibernate.customer Member_YENI = new customer();
Member_YENI.setbayi_kodu(14);
Member_YENI.setemail("coder@gmail.com");
Member_YENI.setusername("kutayzorlu");
        

SessionFactory sessionFactory =
hibernate.util.getSessionAnnotationFactory();

Session session = sessionFactory.getCurrentSession();
session.beginTransaction();
session.save(Member_YENI);
session.getTransaction().commit();

// This is  Static defined inside of  utility
util.shutdown();

Totally token 30 seconds,  First initialization. But after 30 seconds,  every update insert delete  taking  lower than 1 second.

 

Neden Hibernate ?

Posted on by coder

 

* Hibernate veri sorgulama(data query) ve veri çekme(data retriaval) işlemlerini icinde barindirir.

* Hibernate geliştirme kolaylığı ve zamandan kazanç sağlar.

* Hibernate kullanımı olmadan tüm adı anılan işlemler için SQL ve JDBC’nin olanaklarından faydalanılarak el ile(manual) veri işleme(data handling) gerçekleştirilmesi vakit kaybIdIr .
