Hibernate Save

save in hibernate

1) Create a table Banner
2) Create a Bean in java and map this hibernate xml file
3) Save this bean using hibernate session and commit.
4) Add hibernate XML file in hibernate config XML file
Above three steps will make a record inserted.

1) Create table banner
( id bigInt primary key,
  banner varchar(3000)
)

2)

package com.banner.beans;

public class Banner {
	private long id;
	private String banner;
	
	
	public long getId() {
		return id;
	}

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

public String getBanner() {
		return banner;
	}

public void setBanner(String banner) {
		this.banner = banner;
	}
}
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Below is Banner.Hib.xml file, make this file  entry in Hibernate config file
For Primary key auto generation we used below
 <id name="id" type="long" column="id" >
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC 
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
  <class name="com.banner.beans.Banner" table="banner">
  <id name="id" type="long" column="id" >
   <generator  class="increment"/>
  </id>
  <property name="banner">
     <column name="banner" />
  </property>
  
 </class>
</hibernate-mapping>

3) Insert a Record using hibernate -- below is the classe file which is used to save this record in database
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
package com.banner.insert;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

import com.banner.beans.Banner;

public class SaveBanner {
	public void saveProduct(Banner product)
	{
		System.out.println("Before Inserting Record");
		Session session = null;

try{
	      
	SessionFactory sessionFactory = new 
	Configuration().configure().buildSessionFactory();
	      
	       session =sessionFactory.openSession();
	        //Create new instance of Contact and set 
	       org.hibernate.Transaction transaction = session.beginTransaction();
	      
	       //	values in it by reading them from form object
	        System.out.println("Inserting Record");	  
	        
	     
	        session.save(product);	        
	         
	        transaction.commit();
	        System.out.println("  Record inserted");	 
	        
	    }
	    catch(HibernateException he)
	    {
	    	System.out.println(he);
	    	System.out.println(he.getMessage());
	    }
	    finally{
	      // Actual contact insertion will happen at this step
	    	try{
	      session.flush();
	      session.close();
	      
	    }catch (Exception e) {
			System.out.println(e);
		}
		
	}
	}

}

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
See in db a new record is inserted
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
4) Add this in hib config
Sample hib config is as below
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>
      <property name="hibernate.connection.driver_class">

com.mysql.jdbc.Driver</property>
      <property name="hibernate.connection.url">

jdbc:mysql://localhost/shop</property>
      <property name="hibernate.connection.username">root</property>
      <property name="hibernate.connection.password">narayana</property>
      <property name="hibernate.connection.pool_size">100</property>
      <property name="show_sql">true</property>
      <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
     <property name="hibernate.hbm2ddl.auto">update</property>
      <mapping resource="deals.hbm.xml"/>
       <mapping resource="classified.hbm.xml"/>
       <mapping resource="banners.hbm.xml"/>
       
</session-factory>
</hibernate-configuration>
