Developing Java Applications with Spring and Spring Boot

Overview of this book

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.

Introduction


What good is an application unless it is being used? In today's day and age—when DevOps has become the way of doing software development, when the cloud is the king, and when building microservices is considered the thing to do—a lot of attention is being focused on how applications get packaged, distributed, and deployed in their designated environments.

The Twelve-Factor App methodology has played an instrumental role in defining how a modern Software as a Service (SaaS) application is supposed to be built and deployed. One of the key principles is the separation of environmental configuration definitions from the application and storage of this in the environments. The Twelve-Factor App methodology also favors the isolation and bundling of the dependencies, development versus production parity, and ease of deployment and disposability of the applications, among other things.
