Spring is a massive ecosystem. In this focused, hands-on guide you'll learn the parts you really need and learn them really well.Nothing beats a good, modern, and recent introductory book on Spring. That's something I wish it was available some years back when I first encountered Spring.
Spring is a must-learn tool for Java developers. Spring Quickly introduces you to Java development with Spring by concentrating on the core concepts you'll use in every application you build. You'll learn how to refactor an existing application to Spring, how to use Spring tools to make SQL database requests and REST calls, and how to secure your projects with Spring Security. There's always more to learn, and this book will make your next steps much easier.
About the Technology
Spring Framework is packed with features to make your applications fast, maintainable, robust and secure. This extensive ecosystem of tools for cloud computing, microservices, and more have made it the de facto choice for building enterprise Java applications.About the book
Spring Quickly teaches you how to build professional-quality applications using Spring and Spring Boot. Author Laurentiu Spilca draws on a decade of Java experience to show you when, where, and why to use Spring in existing and brand-new apps. You'll start with the core components of the framework and then learn how features like Spring Boot simplify the tedious repetitive tasks you face in every project. When you're done, you'll be able to create Spring apps, secure it with authentication and authorization, and move on to the next exciting steps of your Spring journey.
