In the previous articles…

As we introduced in the first article, Spring is an excellent tool for Java application development. We also explored how to set up a basic project and create an initial, simple API.

In this article, we’ll connect the project to a database, specifically PostgreSQL, and explore how to persist and manipulate saved data.

PostgreSQL

PostgreSQL, originally known as “post-ingres,” was conceived by Michael Stonebraker in 1985. It serves as a robust alternative to other relational databases like MySQL. The key distinction of PostgreSQL lies in its support for defining custom data types (based on standard SQL types) and data type inheritance.

JWT Authentication

Have you ever noticed that some websites have a private section that requires a username and password to access? You might also have noticed that, once logged in, you’re often not asked to re-enter your username and password for subsequent visits. In stateless web applications, this behavior is achievable by using a JWT token. JWT, which stands for JSON Web Token, is a data exchange standard defined by RFC7519 in 2015.

What is a Framework

A Framework, in simple terms, is a set of predefined classes, libraries, and tools that provide a basic structure for software development. The use of a framework allows developers to avoid implementing basic features from scratch, enabling them to focus on developing specific, customized functionalities for their projects.

Spring

Spring is an open-source framework for Java application development. The first version of the framework was released in 2003 by Rod Johnson, and it has been enhanced over the years with a series of extensions. Over time, Spring has earned a leading role in Java application development, thanks to its highly active community and the vast availability of documentation and practical examples.
