Hibernate hello world example eclipse

Step 1: Download the hibernate 3.6 final distribution.

Click to download Hibernate 3.6 final distribution download.

Step 2: Required jar files are,

required library files for hibernate

Step 3: Create a Java project in the eclipse and Create a registration configuration xml file inside src folder (which has the connection information like url, username password etc…)

Create a file named “registration.cfg.xml” and paste the below code,

Note: Filename can be anything but extension must be .cfg.xml.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

        <!-- Database connection configurations -->
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/signup</property>
		<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password"></property>

        <!-- Making autocommit false -->
        <property name="hibernate.connection.autocommit">false</property>

        <!-- Displaying sql queries when running the program -->
        <property name="show_sql">true</property>
        <property name="format_sql">true</property>
        <property name="use_sql_comments">true</property>

        <!-- For JDBC connections -->
        <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>

        <!-- Mapping file -->
        <mapping resource="registration.hbm.xml"/>



Note: Url, Username Password and dialect informations are available for all the databases in the configuration file which is in “project -> etc (contains all the properties of all databases)”  of hibernate 3.6 distribution final folder (which is downloaded in step 1).

Step 4: Create a table with this attribute in mysql,

username(varchar) 20 primary key, email(varchar) 30, password (varchar) 20

Step 5: Create a Pojo class (Registration) for table attributes (username, email and password) and paste the below code,

public class Registration {
	public Registration(){}
	private String userName;
	private String emailId;
	private String password;
	public String getUserName() {
		return userName;
	public void setUserName(String userName) {
		this.userName = userName;
	public String getEmailId() {
		return emailId;
	public void setEmailId(String emailId) {
		this.emailId = emailId;
	public String getPassword() {
		return password;
	public void setPassword(String password) {
		this.password = password;


Step 6: Create a mapping xml file which map the column and the attribute of the above Pojo class (setter and getter).

Create a file named “registration.hbm.xml” and paste the below code,

Note: File name can be anything, but extension must be .hbm.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

    <class name="Registration" table="Registration">
        <id name="userName" column="USERNAME" type="string">
            <generator class="assigned"></generator>
        <property name="emailId" column="EMAILID" type="string"></property>
        <property name="password" column="PASSWORD" type="string"></property>


Copy the doctype(3rd line) from the file (project -> core ->source ->main ->resources -> org ->hibernate ->(mapping file)) for the above mapping file, it is not a mandatory one, to ensure the things right we can do this.

Step 7: Create a business class named “RegisterDetails” and paste the below code,

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

public class RegisterDetails {

	 * @param args
	public static void main(String[] args) {
		Configuration cfg = new Configuration();
		SessionFactory sf = cfg.buildSessionFactory();
		Session s = sf.openSession();
		Transaction tx = s.beginTransaction();

		Registration reg = new Registration();




Run the program and the values are inserted into the db and the query will be displayed in the console.


/* insert Registration
*/ insert
(?, ?, ?)

Easy Understand :

  • Hibernate configuraion xml file which is to hold the connection details such as url, username, password, dialect(to generate queries) and driver class details.
  • Pojo class for the required attributes.
  • Hibernate mapping xml file to map the pojo class attributes with the table columns.
  • Business class to write the business code, we have written value insertion details here.
