You might have heard from IT employees that there is no work-life balance in IT due to unrealistic deadlines, long working hours, etc. I did work crazy hours in the first 7 or 8 years of my career, but not anymore. Fortunately, I have been working in the companies that value work-life balance, and I never had to work beyond 8 hours in the recent past. However, I have been working on writing blogs, making videos, etc.

I have been using Java for more than 17 years, and I really like Java and its ecosystem. Within the Java ecosystem, Spring Boot is my go-to framework for building applications. I used the Go language for an official project a couple of years ago, and initially I had mixed feelings about it. But the more I use it, the more I like it. I wanted to expand my skill set and decided to get more hands-on experience with Go.

I joined AtomicJar as a Developer Advocate on 1st November 2022. Time flies when you are enjoying your work, isn’t it. Before joining AtomicJar, I worked as a TechLead/Architect at various companies for more than 15 years. When I got the opportunity to join AtomicJar, I was very excited to work with my favourite technology Testcontainers. I have been using Testcontainers for more than 4 years, and I am a big fan of it.

jOOQ is a Java persistence library that provides SQL DSL for writing typesafe SQL queries. It supports most of the popular databases like MySQL, PostgreSQL, Oracle, SQL Server, and many more. In this tutorial, we will learn how to get started with jOOQ for implementing persistence layer in a Spring Boot application. You can also use jOOQ in other JVM based languages like Kotlin, Scala, etc. jOOQ Tutorial - 1 : Getting Started jOOQ Tutorial - 2 : Implementing CRUD Operations jOOQ Tutorial - 3 : Fetching One-to-One Relationships jOOQ Tutorial - 4 : Fetching One-to-Many Relationships jOOQ Tutorial - 5 : Fetching Many-to-Many Relationships In this jOOQ tutorial series, you will learn how to use jOOQ in a Spring Boot application for implementing:

In this article, we will learn how to implement Service to Service Communication using Client Credentials Flow. We will create the archival-service in which we will use a scheduler job to invoke the messages-service APIs to archive the messages. For implementing this, we will use Client Credentials Flow. We will also implement POST /api/messages/archive API endpoint in archival-service which can only be called by users who have ROLE_ADMIN role. Considering this, archival-service will act as a Resource Server and as a Client too.

In the previous articles, we have created messages-webapp and messages-service and invoked API endpoints using Postman. In this article, we will learn how to invoke the secured messages-service API endpoints from the Client application messages-webapp. Source Code: You can find the complete source code of this project on GitHub: https://github.com/sivaprasadreddy/spring-security-oauth2-microservices-demo Show List of Messages As GET /api/messages API endpoint in messages-service is publicly accessible, we can invoke it from messages-webapp without any authentication.
