An end-to-end software development guide for the Java eco-system using the most advanced frameworks: Spring and Spring Boot. Learn the complete workflow by building projects and solving problems. About This Book • Learn reactive programming by implementing a reactive application with Spring WebFlux • Create a robust and scalable messaging application with Spring messaging support • Get up-to-date with the defining characteristics of Spring Boot 2.0 in Spring Framework 5 • Learn about developer tools, AMQP messaging, WebSockets, security, MongoDB data access, REST, and more • This collection of effective recipes serves as guidelines for Spring Boot application development Who This Book Is For Java developers wanting to build production-grade applications using the newest popular Spring tools for a rich end-to-end application development experience. What You Will Learn • Get to know the Spring Boot and understand how it makes creating robust applications extremely simple • Understand how Spring Data helps us add persistence in MongoDB and SQL databases • Implement a websocket to add interactive behaviors in your applications • Create powerful, production-grade applications and services with minimal fuss • Use custom metrics to track the number of messages published and consumed • Build anything from lightweight unit tests to fully running embedded web container integration tests • Learn effective testing techniques by integrating Cucumber and Spock • Use Hashicorp Consul and Netflix Eureka for dynamic Service Discovery In Detail Spring Framework has become the most popular framework for Java development. It not only simplifies software development but also improves developer productivity. This book covers effective ways to develop robust applications in Java using Spring. The course is up made of three modules, each one having a take-away relating to building end-to-end java applications. The first module takes the approach of learning Spring frameworks by building applications.You will learn to build APIs and integrate them with popular fraemworks suh as AngularJS, Spring WebFlux, and Spring Data. You will also learn to build microservices using Spring's support for Kotlin. You will learn about the Reactive paradigm in the Spring architecture using Project Reactor. In the second module, after getting hands-on with Spring, you will learn about the most popular tool in the Spring ecosystem-Spring Boot. You will learn to build applications with Spring Boot, bundle them, and deploy them on the cloud. After learning to build applications with Spring Boot, you will be able to use various tests that are an important part of application development. We also cover the important developer tools such as AMQP messaging, websockets, security, and more. This will give you a good functional understanding of scalable development in the Spring ecosystem with Spring Boot. In the third and final module, you will tackle the most important challenges in Java application development with Spring Boot using practical recipes. Including recipes for testing, deployment, monitoring, and securing your applications. This module will also address the functional and technical requirements for building enterprise applications. By the end of the course you will be comfortable with using Spring and Spring Boot to develop Java applications and will have mastered the intricacies of production-grade applications. Style and approach A simple step-by-step guide with practical examples to help you develop and deploy Spring and Spring Boot applications in the real-world.

Discover the real power of Spring Framework 5.0 and learn to create powerful applications in its newest version About This Book • Learn reactive programming by implementing a reactive application with Spring Webflux • Create a robust and scalable messaging application with Spring messaging support • Apply your knowledge to build three real-world projects in Spring Who This Book Is For If you're a developer starting out with Spring, then this book will help you learn about the new Spring 5.0 framework concepts followed by their implementation in Java and Kotlin. The book will also help experienced Spring developers gain insights into the new features added in Spring 5.0. What You Will Learn • Implement REST APIs with Spring REST support • Introduce the Spring Boot and understand how it makes creating robust applications extremely simple • Understand how Spring Data helps us add persistence in MongoDB and SQL databases • Introduce Reactive Programming and use this with Spring Webflux • Implement a Reactive REST client and learn how it can create asynchronous applications • Create a robust, scalable, and fault tolerant application with Spring Messaging • Implement a websocket to add interactive behaviors in your applications • Introduce the Spring Cloud projects In Detail With growing demands, organizations are looking for systems that are robust and scalable. Therefore, the Spring Framework has become the most popular framework for Java development. It not only simplifies software development but also improves developer productivity. This book covers effective ways to develop robust applications in Java using Spring. The book has three parts, where each one covers the building of a comprehensive project in Java and Spring. In the first part, you will construct a CMS Portal using Spring's support for building REST APIs. You will also learn to integrate these APIs with AngularJS and later develop this application in a reactive fashion using Project Reactor, Spring WebFlux, and Spring Data. In the second part, you'll understand how to build a messaging application, which will consume the Twitter API and perform filtering and transformations. Here, you will also learn about server-sent events and explore Spring's support for Kotlin, which makes application development quick and efficient. In the last part, you will build a real microservice application using the most important techniques and patterns such as service discovery, circuit breakers, security, data streams, monitoring, and a lot more from this architectural style. By the end of the book, you will be confident about using Spring to build your applications. Style and approach This book teaches you to use the new version of Spring Framework to solve problems commonly encountered in modern web application; it explains the main features of this version such as support for Reactive programming and Kotlin. You'll learn these features by creating interesting projects and putting them into practice right now.
