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 is a powerful, open-source object-relational database system that provides advanced features such as reliable transactions and concurrency without read locks. This makes it an excellent choice for applications requiring complex data management.
Spring Data JPA, part of the larger Spring Data family, makes it easier to implement JPA-based repositories. This module provides 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.

You taught me hibernate in just 30 mins thats all I needed thanks a lot!

Most tutorial I have been using are too slow, gernal, and I always ran into problems. This was the one of the only tutorial that really allowed me to get the project down and not run into problems because you showed everything in detail. I really appreciate the java, spring, hibernate, and postgres tutorials.

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.

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

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 7 месяцев назад

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.

@mohammedshasilkhan3771 7 месяцев назад

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.

@rit_mos 5 месяцев назад

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