The book quickly takes you through pieces to help you get up to speed with spring boot, where it’s been, what you can do today and where it’s going . It was written so that you have a fairly decent background and what’s being accomplished . My biggest complaint is the lacking of the glossary . This would help people who have already started playing with reactive spring a whole lot. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars As a Spring Developer I found this book extremely helpful *by M***R on Reviewed in the United States on December 15, 2021* There are a few different approaches a programming book can take. One approach is more textual explaining the concepts with small little snippets of code, another is to fill the book with so much code samples that you can see how everything works in the real world and of course a nice mix of both.In Josh Long's book Reactive Spring, he takes the approach of presenting every piece of real world sample code he can provide. It is really great stuff from a Spring FLUX/MVC approach that many are already familiar with to a configuration routing to handlers approach which matches approaches other projects take. Even command line apps that act as servers handling requests and responses. Since there are so many ways you can use Spring Reactive in your projects, you need a book like this that can show you how to use it correctly in your project.Josh has a great way to really describe the code and what is going on, so that you don't have to rack your brain deciphering it. The code is very clean. He explains all the concepts well to also go along with the code. It also comes with Josh's great sense of humor, so much his voice that I literally heard his voice in my head reading the book to me as I read along.If you really want to learn everything about Spring Reactive projects, then this is the book you should get. ### ⭐⭐⭐ 3.0 out of 5 stars Some Good Some Bad *by E***C on Reviewed in the United States on June 7, 2022* Initially I really enjoyed reading this book, I even didn't mind the first few chapters which were a basic intro to Spring, which is something I'd generally skip over, but read it anyways because I enjoyed how it was written. Passed the Spring intro and reactive intro, I started to see a few problems when diving into the heart of the book:0) Josh sells reactive hard, but I think that's a tough pill to swallow. Even 2 years after the publication of the book, I think spring reactive is still a little rough around the edges. For example, at one point R2DBC is mentioned as an experimental feature. I was glad to learn about it, until I learned even now R2DBC (relational database connectivity i.e reactive jdbc) has no production ready db drivers.1) One repeating theme of the book is, "That was Easy!". Sure, you can understand and implement the examples, but let's be honest reactive can get pretty complicated. Many of the "simple" examples are really non-trivial when you actually look closely.2) I'm not a fan of how the chapter examples are structured. I think examples should be like tests, from the standpoint what you see is what you get. In some chapters there is a separate common module which performs setup tasks. The problem is, some of those setup tasks are only used by a single example in the chapter (ie. a ton of setup to handle RSocket headers, which is only used by 2 examples).3) It was annoying that it wasn't mentioned that Thread.currentThread().join() was added to the Main class in RSocketRequester and WebClient examples. I can't be the only one who spent too long getting a trivial example to work only to realize that the user thread was exiting before the daemon thread performing the request could complete. For concurrency work, this is kind of basic, but with all of Springs abstraction away of the Threads, I really think this deserved discussion.Final thoughts. I don't regret reading this book. I will only use Reactive if I absolutely have to, and am looking forward to other projects that make it obsolete. I enjoy Josh's writing, but I do think up he could clean up his examples to avoid internal dependencies. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/234005380-reactive-spring](https://www.desertcart.at/products/234005380-reactive-spring) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-23*
