Securing REST APIs with OAuth2 and JWT: A Comprehensive Guide

In today’s interconnected world, REST APIs are a critical component of modern web applications. However, securing these APIs is essential to protect sensitive data and ensure that only authorized users can access resources. One of the most effective ways to secure RESTful APIs is by using OAuth2 and JSON Web Tokens (JWT). In this guide, we will explore how to implement these security measures, focusing specifically on the authorization_code grant type and using a third-party service like Auth0 as the authorization server.

Spring Security: Implementing JWT Authentication in Your Java Application

In the modern world of web development, securing your applications is of paramount importance. One of the most effective ways to do this in a Spring Boot application is by using JSON Web Tokens (JWT). This blog post will guide you through the essentials of Spring Boot, JWT, and how to implement JWT authentication using Spring Security. We’ll also touch on the differences between JWT and opaque tokens and provide code examples.

Testing Spring Boot Applications: Unit, Integration, and Mocking — A Comprehensive Guide

Testing is a critical aspect of software development, ensuring the reliability and stability of your applications. In this blog post, we’ll dive into the essentials of testing Spring Boot applications using JUnit and Mockito. We’ll cover unit tests, integration tests, and mocking, providing examples using MockServer and Testcontainers.

Deploying Spring Boot Applications to AWS

Deploying applications to the cloud has become a standard practice for modern software development, providing scalability, reliability, and ease of maintenance. In this blog post, we will explore how to deploy a Spring Boot application to Amazon Web Services (AWS). While there are multiple ways to deploy applications on AWS, we will focus on using Elastic Beanstalk and ECS (Elastic Container Service) as they are popular and widely used solutions.

Beware of Spring Boot Actuator Endpoint env: A Security Alert

As a developer, securing your applications should be a top priority. One area that often goes unnoticed in Spring Boot applications is the Actuator env endpoint. In this blog post, we will explore the potential security issues associated with this endpoint and provide tips on how to mitigate these risks.

Spring Observability: The Next Frontier in Application Monitoring

In the evolving landscape of software development, observability has emerged as a crucial aspect of maintaining and improving application performance. Historically, developers relied on third-party libraries like Micrometer and Micrometer Tracing to achieve observability in their Spring applications. However, with the release of Spring 6 and Spring Boot 3, observability has been elevated to a first-class citizen within the framework itself.

Spring AI: Revolutionizing Backend Development with AI Integration

In the rapidly evolving landscape of technology, artificial intelligence (AI) is no longer a futuristic concept — it’s a present reality that’s transforming how we build and interact with software. For backend engineers, integrating AI into applications has often been a complex and time-consuming task. Enter Spring AI, a revolutionary framework designed to simplify and accelerate AI integration in Spring Boot applications. In this post, we will explore what Spring AI is, its key features including boot auto configuration support, the AIs it supports, and how you can get started with some code examples. We’ll also touch on core AI concepts like prompts and tokens and share the development roadmap for Spring AI.

Testing the Integration Layer of Your Spring Boot Application with Testcontainers and MockServer

In modern microservices architectures, robust and reliable integration testing is crucial to ensure seamless communication between services. Integration tests verify that different parts of the application work together as expected. This blog post will dive into how to effectively test the integration layer of your Spring Boot application using Testcontainers and MockServer, two powerful tools that simplify and enhance the testing process.

Understanding the Differences Between @Controller and @RestController Annotations

In the world of Spring Framework, particularly in Spring MVC, @Controller and @RestController are two annotations that play crucial roles in defining endpoints and handling HTTP requests. While both are used for building web applications, they serve slightly different purposes and have distinctive behaviors. Let’s delve into the nuances of each annotation to better comprehend their functionalities and use cases.
