Hibernate Simple Example Using Annotation

Create Maven Project:Create java project , convert that to maven bases project

Add Dependency:
pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Add configuration file at class path:
hibernate.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">

<hibernate-configuration>

<session-factory>

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

    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/masterjee</property>

    <property name="hibernate.connection.username">root</property>

    <property name="hibernate.connection.password">root</property>

    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

    <property name="hibernate.show_sql">true</property>

    <property name="hbm2ddl.auto">update</property>

    <mapping class="com.akt.User"/>

</session-factory>

</hibernate-configuration>

Add your Entity class
User.java

package com.akt;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.Id;

import javax.persistence.Table;

@Entity

@Table(name="user")

public class User {

@Id

@GeneratedValue

@Column(name="userId")

private int userId;

@Column(name="name")

private String name;

@Column(name="email")

private String email;

@Column(name="password")

private String password;

@Column(name="age")

private int age;

@Column(name="salary")

private long salary;

public int getUserId() {

return userId;

}

public void setUserId(int userId) {

this.userId = userId;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getEmail() {

return email;

}

public void setEmail(String email) {

this.email = email;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public long getSalary() {

return salary;

}

public void setSalary(long salary) {

this.salary = salary;

}

}

Add MainClass.java

package com.akt;

import org.hibernate.*;

import org.hibernate.cfg.Configuration;

public class MainClass {

public static void main(String[] args) {

Configuration configuration = new Configuration();

configuration.configure("hibernate.cfg.xml");

SessionFactory sessionFactory = configuration.buildSessionFactory();

Session session = sessionFactory.openSession();

Transaction transaction = session.getTransaction();

transaction.begin();

User user = new User();

user.setName("Anil");

user.setEmail("anil.thakur0909@gmail.com");

user.setPassword("test123");

user.setSalary(1500);

user.setAge(28);

session.persist(user);

transaction.commit();

session.close();

sessionFactory.close();

}

}
