Book Description:

In today's dynamic landscape, crafting robust and scalable Java web applications presents formidable challenges. Spring Boot emerges as the leading framework for web and microservices development, featuring a dynamic ecosystem and seamless integrations to address a spectrum of scenarios, from scaling apps on the cloud to deploying them to production. In this book, you'll explore its streamlined, convention-over-configuration approach, simplifying application development.

You'll start by covering recipes showcasing Spring Boot's features. As you progress, you'll understand how it helps streamline application development while staying ahead of technology trends. The book helps you grasp concepts effectively, explores basic REST APIs, shows you how to escalate to advanced scenarios, and tackle common cloud application challenges like security, scalability, performance optimization, and automated deployments. Dedicated sections are designed to help you stay ahead of the curve with recipes that delve into the latest trends such as containers, observability, native images, DevOps, test automation, and microservices, ensuring your applications align with evolving industry standards.

By the end of this book, you'll be able to build and automate the deployment of a scalable and high-performing distributed solution using Spring Boot 3.

What You Will Learn:

- Develop production-grade distributed applications

- Use various data repositories, including relational and NoSQL databases

- Implement modern testing techniques across different levels of application development

- Leveraging Testcontainers to validate all integration scenarios

- Integrate with services like Redis, PostgreSQL, MongoDB, and RabbitMQ

- Authenticate through OpenID providers

- Facilitate smooth migration from earlier Spring Boot versions

Who this book is for:

This book is for Java developers who want to gain expertise in modern web development, architects designing complex systems, experienced Spring Boot developers and technology enthusiasts looking to stay up to date with the latest trends, and software engineers in need of practical solutions for everyday challenges. Hands-on experience with Java or Kotlin is required. Prior development experience on the cloud will be useful, but not necessary.
