Dear freinds... I want to know how to write self mapping
for a table using hibernate?
Answer / dsr
contact.java
------------
package com.tutorial.hibernate;
public class Contact {
private String firstName;
private String lastName;
private String email;
private long id;
public String getEmail() {
return email;
}
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public void setEmail(String string) {
email = string;
}
public void setFirstName(String string) {
firstName = string;
}
public void setLastName(String string) {
lastName = string;
}
public long getId() {
return id;
}
public void setId(long l) {
id = l;
}
}

FirstExample.java
------------------
package com.tutorial.hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class FirstExample {
public static void main(String[] args) {
Session session = null;
try {
SessionFactory sessionFactory = new
Configuration().configure()
.buildSessionFactory
();
session = sessionFactory.openSession
();
Transaction tx =
session.beginTransaction();
Contact contact = new Contact();
contact.setId(3);
contact.setFirstName("sita");
contact.setLastName("ram");
contact.setEmail
("sitam75@gmail.com");
session.save(contact);
tx.commit();
} catch (Exception e) {
System.out.println(e.getMessage());
} finally {
// Actual contact insertion will
happen at this step
session.flush();
session.close();
}
}
}
--------------------------------------------------------
contact.hbm.xml
---------------
<?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.tutorial.hibernate.Contact"
table="CONTACT">
<id name="id" type="long" column="ID" >
<generator class="assigned"/>
</id>
<property name="firstName">
<column name="FIRSTNAME" />
</property>
<property name="lastName">
<column name="LASTNAME"/>
</property>
<property name="email">
<column name="EMAIL"/>
</property>
</class>
</hibernate-mapping>
