Spring Boot 3.0 Cookbook: Proven recipes for building modern and robust Java web applications with Spring Boot

The book is incredibly well-organised, making it easy to follow along and build upon each concept. Spring boot 3.0 cookbook provides numerous code snippets and detailed explanations, making complex topics accessible and understandable. The examples are not just theoretical but are applicable to real-world scenarios, which is a huge plus.

I reviewed this book at the request of the author and I'm sharing it here for others.The book offers a well rounded and comprehensive collection of practical recipes that cover a wide range of topics essential for modern web and microservices development using Spring Boot 3.0.Practical and Hands-On:The book excels in providing step-by-step instructions for building RESTful APIs, securing applications with OAuth2, and integrating with various databases. Each chapter is filled with real-world examples that are easy to follow and implement.Focus on Modern Practices:It emphasizes current best practices, including observability, monitoring, and application management. The sections on Spring Cloud and reactive programming are particularly useful for architects designing scalable and resilient systems.Comprehensive Coverage:From basic CRUD operations to advanced topics like distributed tracing and native image creation, the book covers a broad spectrum of Spring Boot features. This makes it a one-stop guide for both beginners and experienced developers.Clear and Concise:The book is well-organized content and makes complex concepts accessible. The inclusion of technical requirements and detailed explanations ensures that readers can easily replicate the examples. The recipes format is useful starting from ‘Getting Ready’ to ‘How to do it’ with a follow up overview in ‘How it works’It’s definitely a book which helps developers to get started and also experienced developers and architects to close gaps in knowledge and a fundamental working knowledge of Spring Boot 3.0 Cookbook.

I actually found this book before it was even released. I was searching for books on Java and Spring when I came across "Spring Boot 3.0 Cookbook", which wouldn't be released for a couple more months. 😩 I was so excited to get my hands on it that I literally set a reminder in my phone to order it the day it was released on Amazon. 😅When it finally arrived, I jumped right into reading about automated testing, mocking services, and implementing security protocols like OAuth2. (Not my favorite topics, to be honest, but they're my weakest areas and I'm trying to get better at them so 🤷🏽‍♀️, here we are. 😮‍💨😅)The book emphasizes the importance of automated testing over manual testing due to its scalability and efficiency. It covers the basics of unit and integration testing using Spring Boot's built-in testing starter. For the longest time, I didn't know the difference between the different types of testing (they're all just testing to me 🤷🏽‍♀️🥴), so this part was pretty helpful. 😅It also covers how to mock remote dependencies using Wiremock. The book explains how to configure Wiremock and integrate it with Spring Boot for testing, which I found pretty helpful because even though I've definitely created mocks for testing before, I used MockMVC to do it, so Wiremock was completely new to me. 🤯The security section is really detailed and covers setting up an Authorization Server, protecting APIs with OAuth2, and configuring different scopes and client authentication methods. It explains handling various OAuth2 flows, such as client credentials and authorization code grant flows.I found this part helpful since I'm still pretty new to OAuth2 and have mostly used JWT up until now. 😕 (Speaking of which, it also explains how to use JWT tokens for secure communication and validation. 😉)The book also mentions integration with social providers like GitHub and Facebook and even walks you through integrating Google Account login into your Spring Boot applications. Now this is the part I was excited about!! 🤩😁 By configuring your Authorization Server as an OAuth2 client with Google as the Identity Provider (IdP), you can enable users to log in with their Gmail accounts.It also explains how to configure the security chain using Spring Security's 'SecurityConfig' class, detailing the setup of 'Security FilterChain' beans to handle various security checks and the login process. This part was definitely helpful for me because 'Security FilterChain' was one of the things that my bootcamp just completely glossed over. 😕 It was kinda like "Paste these snippets of code into such-and-such class to implement security", and that was it. 🫤🤷🏽‍♀️There's a chapter where the book teaches you to identify performance bottlenecks and optimize your application. Now this stuff was completely new to me. 😳 Thankfully, it guides you through the entire process, from identifying issues to applying solutions like caching and runtime tuning.It clearly explains the impact caching has on overall performance. By reducing the load on the database through caching, the application can handle more requests efficiently, demonstrating the real-world benefits of proper caching strategies.The book also talks about monitoring and application health and covers metrics like CPU usage, heap memory, etc. explaining the importance of diagnosing and fixing performance issues.Overall, I think this book is a great resource for Java developers and it's packed with clear explanations and detailed examples to help you develop secure RESTful APIs with Spring Boot. 😊 I literally waited months for this book to be released and I can honestly say that it exceeded my expectations!! 😁

Spring Boot has become the default framework for developing applications and services on the Java platform more quickly, which has given a new dynamism to this platform, along with the new functionalities of recent versions of Java.This book offers us several recipes to take advantage of this platform in an optimal way.Another good book that I add to my shelf on the Java platform with Spring.

This book is a must have for those looking to expand their knowledge of Springboot. This book is great for beginners or pros. Chapter 8 Reactive Spring is a fun read and very helpful sense I am new to this approach. Thanks for providing this awesome book, I'm looking foward to more great content from this Author/Authors.
