Spring in Action

Product Information

One of the most amazing things that Spring and Spring Boot do is to automatically provide all of the foundational plumbing for an application, leaving you as a developer to focus primarily on the logic that’s unique to your application. Unfortunately, no such magic exists for writing a book. Or does it? As for the dependencies themselves, you can either expand the various sections and seek out the desired dependencies manually, or search for them in the search box at the top of the Available list. For the Taco Cloud application, you’ll start with the dependencies shown in figure 1.4. Part 1 of this book will get you started writing a Spring application, learning the foundations of Spring along the way. Craig Walls is a software developer at Pivotal. He's a popular author and a frequent speaker at user groups and conferences. Craig lives in Cross Roads, Texas. Video description In Video Editions the narrator reads the book while the content, figures, code listings, diagrams, and text appear on the screen. Like an audiobook that you can also watch as a video.

You’re freed from the burden of worry about library versions. You can trust that for a given version of Spring Boot, the versions of the libraries brought in transitively will be compatible. You only need to worry about which version of Spring Boot you’re using. CRAIG WALLS is a principal engineer with Pivotal. He’s a zealous promoter of the Spring Framework, speaking frequently at local user groups and conferences and writing about Spring. When he’s not slinging code, Craig is planning his next trip to Disney World or Disneyland and spending as much time as he can with his wife, two daughters, two birds, and three dogs. About the cover illustrationNext, take note of the element and, more specifically, its child. This specifies that your project has spring-boot-starter-parent as its parent POM. Among other things, this parent POM provides dependency management for several libraries commonly used in Spring projects. For those libraries covered by the parent POM, you won’t have to specify a version, as it’s inherited from the parent. The version, 2.0.4.RELEASE, indicates that you’re using Spring Boot 2.0.4 and, thus, will inherit dependency management as defined by that version of Spring Boot. The figure on the cover of Spring in Action, 5th edition, is Le Caraco, or an inhabitant of the province of Karak in southwest Jordan. Its capital is the city of Al-Karak, which boasts an ancient hilltop castle with magnificent views of the Dead Sea and surrounding plains. The illustration is taken from a French travel book, Encyclopédie des Voyages by J. G. St. Sauveur, published in 1796. Travel for pleasure was a relatively new phenomenon at the time and travel guides such as this one were popular, introducing both the tourist as well as the armchair traveler to the inhabitants of other regions of France and abroad. Finally, to my beautiful wife Raymie, the love of my life, my sweetest dream, and my inspiration: Thank you for your encouragement and for putting up with another book project. And to my sweet and wonderful girls, Maisy and Madi: I am so proud of you and of the amazing young ladies you are becoming. I love all of you more than you can imagine or I can possible express. About this book

Craig Walls is an engineer at VMware, a member of the Spring engineering team, a popular author, and a frequent conference speaker. The best resource for modern Spring development. Although the Greek philosopher Heraclitus wasn’t well known as a software developer, he seemed to have a good handle on the subject. He has been quoted as saying, The only constant is change. That statement captures a foundational truth of software development. Craig Walls is a principal software engineer at Pivotal, a popular author, an enthusiastic supporter of Spring Framework, and a frequent conference speaker. You may also notice that all three dependencies have the word starter in their artifact ID. Spring Boot starter dependencies are special in that they typically don’t have any library code themselves, but instead transitively pull in other libraries. These starter dependencies offer three primary benefits: Designed in 2003 as a lighter approach to J2EE development, Spring Framework has since become a standard choice for building enterprise applications and required knowledge for Java developers. Spring 4 provides full Java 8 integration along with key upgrades like new annotations for the IoC container, improvements to Spring Expression Language, and much-needed support for REST. Whether you're just discovering Spring or you want to absorb the new features, there's no better way to master Spring than with this book.To get started with a new Spring project in Spring Tool Suite, go to the File menu and select New, and then Spring Starter Project. Figure 1.2 shows the menu structure to look for. Chapter 8 looks at using asynchronous communication to enable a Spring application to both send and receive messages using the Java Message Service, RabbitMQ, or Kafka. I’m happy to say that this fifth edition of Spring in Action covers all of this and more! If you’re a seasoned veteran with Spring, Spring in Action, Fifth Edition will be your guide to everything new that Spring has to offer. On the other hand, if you’re new to Spring, then there’s no better time than now to get in on the action and the first few chapters will get you up and running in no time!

As the Taco Cloud application grows, you’ll fill in this barebones project structure with Java code, images, stylesheets, tests, and other collateral that will make your project more complete. But in the meantime, let’s dig a little deeper into a few of the items that Spring Initializr provided. Nearly 100,000 developers have used the book version to learn Spring! Spring in Action requires a working knowledge of Java.Chapter 5 reveals how to configure a Spring application using Spring Boot configuration properties. You’ll also learn how to selectively apply configuration using profiles. This book contains many examples of source code both in numbered listings and inline with normal text. In both cases, source code is formatted in a fixed-width font like this to separate it from ordinary text. Sometimes code is also in bold to highlight code that has changed from previous steps in the chapter, such as when a new feature adds to an existing line of code. As its name suggests, Spring Tool Suite is a fantastic Spring development environment. But it also offers a handy Spring Boot Dashboard feature that (at least at the time I write this) isn’t available in any of the other IDE options.
