    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">
    <hibernate-configuration>
    <session-factory>

    <!-- Disable the second-level cache -->
    <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">true</property>
    <property name="hbm2ddl.auto">update</property>
    <mapping resource="Offer.hbm.xml"/>
    </session-factory>
    </hibernate-configuration>
