Java, Spring Boot, PostgreSQL, Spring Data JPA, Hibernate CRUD RESTFul API Tutorial [2024]
Welcome to the comprehensive video tutorial on creating a CRUD RESTful API using Spring Boot, PostgreSQL, Spring Data JPA, and Hibernate for 2024. This tutorial is designed for developers of all skill levels interested in advancing their knowledge in building robust, scalable, and efficient web applications with some of the most powerful technologies in the Java ecosystem.
Spring Boot, a revolutionary framework, simplifies the development of new Spring applications through convention over configuration. It offers a vast array of features that enable developers to focus on their application's functionality rather than the boilerplate configuration.
PostgreSQL, a powerful, open-source object-relational database system, provides advanced features such as reliable transactions and concurrency without read locks, making it an excellent choice for applications requiring complex data management.
Spring Data JPA, a part of the larger Spring Data family, makes it easier to implement JPA-based repositories. This module deals with enhanced support for JPA based data access layers, making it a breeze to work with data in relational databases.
Hibernate, an object-relational mapping (ORM) tool, simplifies the data creation, retrieval, update, and deletion operations in databases. It is a robust framework that handles all the heavy lifting of connecting your Java classes to a database using JPA annotations.
By the end of this tutorial, you'll have a clear understanding of how to leverage these technologies to create a fully functional CRUD RESTful API. You'll learn how to set up your development environment, configure your database, define your data model, and implement the necessary create, read, update, and delete operations accessible through a clean and intuitive API. Whether you're looking to build your first API or aiming to sharpen your development skills, this guide will provide you with the knowledge and tools needed to succeed. Let's dive in and explore the powerful combination of Spring Boot, PostgreSQL, Spring Data JPA, and Hibernate.

This video provides a clear and thorough explanation, making it easy to understand. It would be beneficial to include additional videos covering topics such as Spring Security, pagination, communicating with other APIs/endpoints, sessions, caching, and various real-time modules. These topics are essential for real-time project development and would greatly benefit viewers looking to delve deeper into practical applications. Thanks in advance.

Please make voice at good level. Project is good and adding value. Thanks alot.
Amazing video, thank you so much! It was so well explained! I was wondering, how could we optimized those classes/interfaces. I did make a generic Service and Repository, so it can be use for more than one Entity, is that correct? if so, is there other ways to optimaze? like other classes that could be generic? Sorry if its a dumb question, I'm new to this
Amazing tutorial you put together! Seriously, it was super insightful and really helped clear things up. Great job, and keep up the awesome work!. Bro you missed cover the exception, it is not working actually
Can you pls make a video explaination of spring security for jpa authentication using security @configuration class...it is quite confusing...pls
Always confused with Annotations 🤯
Getting the below error, what would be the cause? Factory method 'dataSource' threw exception with message: Failed to load driver class org.postgresql.Driver in either of HikariConfig class loader or Thread context classloader
Thank you sir!! I had a query -> why can't we directly use Employee (eliminating the use of DTOs)?

what about pagination and validation ?!
I am having a question here is SimpleJpaRepository class is annotated with @Repository and @Transactional annotations but if we write our own methods in the repository interface, will this be applicable for those methods or not.
@JavaGuides
5 ай бұрын
The @Repository and @Transactional annotations on SimpleJpaRepository do apply to custom methods in your repository interface with the default settings. If you require custom transactional behavior, you will need to add the @Transactional annotation to your custom methods with the specific configuration you need.

Yeah even I get that problem while using lombok. Instead, I would just generate the getters and setters manually in the source option to resolve this, so please try that. And Even I don't know why the lombok annotations are not working properly many times.

You have to install and activate the lombok plugin on your IDE so that the annotations work.
