JPA | Learn Spring Boot, Spring Data JPA & Hibernate Basics

Hi there,

Welcome to my "JPA | Learn Spring Boot, Spring Data JPA & Hibernate Basics" course.
Spring Data JPA, Spring Boot with Rest API examples on PostgreSQL & also different databases like MySQL, MSSQL, MongoDB

Spring Data JPA is a part of the larger Spring Data project, which aims to simplify data access and manipulation in Spring-based applications. Specifically, Spring Data JPA provides a high-level, abstracted approach to working with relational databases using the Java Persistence API

In the world of software development, simplification is often the key to productivity and efficiency. Spring Boot and Spring Data JPA are two powerful tools in the Spring Framework ecosystem that make it easier to develop robust and maintainable Java applications, especially when it comes to working with databases.

Spring Boot: The Foundation of Modern Java Applications

Spring Boot is a part of the Spring Framework that is designed to simplify the process of building production-ready applications. It achieves this by providing a set of conventions and tools to eliminate the need for extensive configuration, boilerplate code, and a steep learning curve .

Spring Boot embraces the concept of "opinionated defaults" . It comes with predefined configurations for common scenarios, such as database connections, web servers, and templating engines . This allows developers to get started quickly without having to make countless decisions .

One of the standout features of Spring Boot is its auto-configuration. It automatically configures components based on the dependencies you include in your project. If you're using Spring Data JPA, Spring Boot will configure your data source, entity manager, and transaction management with sensible defaults.

Spring Boot includes support for embedded servers like Tomcat, Jetty, and Undertow . You don't need to deploy your application to an external server; Spring Boot packages the server with your application, making it easy to run and deploy.

• Spring Basics

• Lombok

• Postman,

• Docker

• DBeaver

• Postgre Database

• Spring Rest API

• sorting and pagination

• Relationships of Entities

• Using JPA with different Databases.

Let's examine the benefits of Spring Data JPA

Repository Abstraction

Spring Data JPA introduces the concept of repositories. These are interfaces that define common database operations, such as saving, retrieving, and deleting entities. You can create custom repository interfaces to define your own data access methods, and Spring Data JPA generates the corresponding implementations.

Query Methods

One of the standout features of Spring Data JPA is the ability to define query methods by method naming conventions. It can derive queries from method names, which makes it easy to create custom queries without writing SQL or JPQL queries manually. For example, a method named findByLastName(String lastName) in a repository interface will automatically generate a query to retrieve entities by their last name .

Automatic CRUD Operations

Spring Data JPA provides automatic implementations for common CRUD operations. You can save, retrieve, update, and delete entities with minimal code, allowing you to focus on your application's business logic.

Pagination and Sorting

Implementing pagination and sorting for your queries is straightforward with Spring Data JPA. It abstracts the complexities of database-specific query syntax, making it easy to retrieve subsets of data.

Integration with Spring Framework

Spring Data JPA seamlessly integrates with the broader Spring ecosystem. It works well with Spring's dependency injection, transaction management, and security features, creating a cohesive development experience .

When you combine Spring Boot and Spring Data JPA, you get a powerful toolkit for building Java applications that interact with databases. Spring Boot provides a strong foundation for your application, with auto-configuration, embedded servers, and cloud-native support, while Spring Data JPA streamlines your data access, reducing the need for boilerplate code and manual SQL queries

So, this course will be a great chance for you to progress faster in the software world

We will start to our course with installing java jdk and most useful IDEs like eclipse and intellij. After that we will learn basic information about spring and Lombok to use in our training. Then we will examine some other tools or apps to use in our training like sts tool, Postman, Docker and postgre Database.

After that we will learn basics of spring API . Because this training is about JPA and I want to teach Data jpa on API pages.

Then we will start spring data JPA.

We will learn some programming concepts like ORM, JPA, Hibernate, Spring data jpa and we will examine differences between them.

After that we will start to JPA with rest API on postgre SQL. We will learn spring annotations that used in JPA like

• Entity

• Id

• Table

• Column

• Generated vale

• Unique constraint

• Auto Identity, Sequence.

Also we will examine JPA repository and most useful methods od JPA repository like

• Save

• Find by

• Save all

• Find all

• Delete

• Delete by Id

• Count and exist by Id.

We will continue with Query methods and Finder methods. After that we will continue with JPQL.

Then we will learn sorting and pagination, relationships between tables like

• One to one

• One to many

• Many to one and many to many.

Also we will examine the search functionality, transaction management and unit testing.

We will make all operations with postgre SQL database. but also we will change our database with difference databases like mysql, mssql, mongo etc.

I think these are enough reasons to start the course. If you're ready, let's get started.
