Java project with Hibernate

Java project with hibernate with source code and project report. Here, I am sharing the list of Java projects using hibernate. Alone, with hibernate it’s using JSP, Servlets, Html, CSS, JavaScript, Bootstrap. Let’s discuss the tools in technologies in detail.

These Hibernate projects are using JSP, HTML, CSS, and bootstrap to manage the front end of the application, It using hibernate to manage the backend and MYSQL to store the data. To deploy the application it’s using Tomcat server, Maven to manage the dependencies, and following MVC architecture will all the industry standards.

What else do you get apart from the project?

Project Report

Yes, We are providing the project report/thesis also that contains all the required UML diagrams. that will help to understand the requirement or you can check the corresponding link to view the specification or overview of the projects.

Remote Support for Project configuration

Let me explain a bit about the remote support and project configuration. In remote support will connect with you using Zoom or Google Meet and In Project configuration will run the project at your machine and make sure it’s working as shows in the demo.

Source code explanation

The developer will directly connect with you so you to explain the complete project, source code flow. So it will help you to understand internal things. Even if you are preparing for a viva or interview our team will help you to face it and train.

Interview and Viva questions

Also, I Will provide a list of the questions that can help you during your Interview or in Viva.

What is hibernate?

Hibernate is a java framework. It’s an ORM(Object-relational mapping) tool. That helps to map the object to the database. It’s a lightweight and open-source tool that provides fast performance as compare to JDBC.

Hibernate uses HQL(hibernate query language) that is the database independent. It means we can write command queries for all the SQL databases.

It provides the facility to create an automatic table so we do not need to create tables manually. So it’s really easy to manage the database using hibernate.

Why Hibernate?

If you are a beginner to develop the java web application. Then it will be good to start to practice with JDBC. But to achieve large-scale project development, it’s really tough to manage the database using JDBC or Datasource. So it’s a really good choice to move toward hibernate.

What is Hibernate?

Hibernate is an Object-Relational Mapping framework in Java Programming Language. It maps the model of object-oriented to the relational database. It provides the framework which simplifies the interaction of the Java Program with the database.

In Java Programming Language, when we work with an application that needs access to the database, we need some interface to connect our Java programming with the database. So, for that, we used JDBC. In this, we just replaced the JDBC with a Framework called Hibernate which will reduce the manual work and make our coding style efficient.

ORM acronyms to Object Relational Mapping tool that enables the developer to write easy code. It provides data persistence in the relational database. ORM tool helps you to map Java classes to database tables and map Java Data type to SQL type.

Why we use hibernate when we had JDBC?

When we are developing any web-based application we need to write some lines of code to map objects of the modal class to the corresponding database. So, instead of writing these lines of code, in Hibernate, developers don’t need to worry about it Hibernate itself takes care of mapping using XML files.
Let’s see the steps to create an application using Hibernate Framework.

  • First, create a project(in IDE simple java project)
  • Download the Jar files
  • Create a database and table in MYSQL.
  • Create a POJO class.
  • Create the mapping files.
  • Create the configuration files.
  • Create a class for retrieving and storing objects.

Download the Jar files:

If you are using Maven just add the dependency inside pom.xml file

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>6.0.0.Alpha6</version>
    <type>pom</type>
</dependency>

If you are adding a jar file follow these steps

  • Right-click on project name>Build path> Configure Build Path
  • Click on Add JARs… then select your project and then select all jar files and click OK and then click apply.
  • Also, add the MYSQL Connector jar file as we do in JDBC.
  1. First Create a database in MYSQL
  1. Create a POJO class:

The persistence class encapsulates the Business Logic. ORM (Object Relational Mapping) responsibility is to take the values from the POJO class and saves its data into the database.

  • It contains a default constructor
  • It should have an id that helps us to identify each element uniquely.
  • Every attribute should have a getter and setter method.
  1. Create a Mapping File:

The ORM (Object Relational Mapping) that does the working of mapping of persistence classes to the database needs a mapping file.

  • We create a mapping file in the XML document.
  • We can also do mapping using annotation from JDK 1.5 version.
  1. Create a Configuration File:
  • In Hibernate, we need to create a Hibernate Configuration hibernate.cfg.xml file
  • Hibernate configuration contains information on the mapping of Java classes into the database table. This information is supply by using any of the two files
    • hibernate.properties
    • hibernate.cfg.xml
  1. Create a Test Class to Store and retrieve Objects.
  • In this class, we will have a physical connection with the database. So, for this, we will use Session Objects.
  • The session is an interface whose Object is provided with SessionFactory.
  • Objects that are saved in the database are retrieved using session objects.
  • The session object is instantiated when SessionFactory is created by the configuration object.
  1. Thus, this is how we create a simple application using Hibernate Framework.

Advantages of Hibernate:

  • It solves the data mismatch problem with the help of the ORM tool.
  • It is open-source software freely available and lightweight.
  • It is database-independent. It can be used to connect with any database.
  • It supports the HQL which is more powerful than SQL and is fully object-oriented.
  • It is highly scalable.
  • It has lazy loading that means it only fetches the necessary object that is required.
  • More importantly, it is easy to learn for any developer.

Different Between JDBC & Hibernate:

JDBC

Hibernate
JDBC stands for Java Database Connectivity Hibernate is an ORM Framework.
It provides an API to connect with the databases. It is a framework to develop objects and persists data using objects.
We have to write some lines of code for mapping objects. In Hibernate, It is taken care of using XML files.
JDBC supports SQL Only. Along with SQL, Hibernate provides a Hibernate Query language.
In JDBC it’s the developer’s responsibility to handle the JDBC resultset. In Hibernate this manual work is handled by maintaining object table mapping.
In JDBC, caching is maintained by manual coding. In Hibernate, it is automatic.
