Hibernate Tutorial Step by Step -- Code Examples

Hibernate mapping with Database TABLE

Follow the steps to mapp with Database TABLE.

Step 1. create a table name OFFER in your database

create table OFFER ( offer_id number; offer_name varchar );

Step 2. Create Offer.java bean class.

package beans;
public class Offer {
private long offerId;
private String offerName;
/**
* @return Returns the offerId.
*/ public long getOfferId() {
return offerId;
}
/**
* @param offerId The offerId to set.
*/
private void setOfferId(long offerId) {
this.offerId = offerId;
}
/** * @return Returns the offerName.
*/
public String getOfferName() {
return offerName;
}
/**
* @param offerName The offerName to set.
*/
public void setOfferName(String offerName) {
this.offerName = offerName;
}
}

Step 3. Offer.hbm.xml - This mapps OFFER TABLE and Offer.java

<?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="beans.Offer" table="OFFER">
<id name="offerId" column="offer_id" type="long">
<generator class="increment"/> // This generates the primary key
</id>
<property name="offerName" column="offer_name"/>
</class>
</hibernate-mapping>

Step 4. add Offer.hbm.xml into hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?>
<lt;!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
