Spring Microservices

Overview of this book

The Spring Framework is an application framework and inversion of the control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions to build web applications on top of the Java EE platform. This book will help you implement the microservice architecture in Spring Framework, Spring Boot, and Spring Cloud. Written to the latest specifications of Spring, you'll be able to build modern, Internet-scale Java applications in no time. We would start off with the guidelines to implement responsive microservices at scale. We will then deep dive into Spring Boot, Spring Cloud, Docker, Mesos, and Marathon. Next you will understand how Spring Boot is used to deploy autonomous services, server-less by removing the need to have a heavy-weight application server. Later you will learn how to go further by deploying your microservices to Docker and manage it with Mesos. By the end of the book, you'll will gain more clarity on how to implement microservices using Spring Framework and use them in Internet-scale deployments through real-world examples.

Target implementation view


The next diagram represents the implementation view of the BrownField PSS microservices system:

As shown in the preceding diagram, we are implementing four microservices as an example: Search, Fare, Booking, and Check-in. In order to test the application, there is a website application developed using Spring MVC with Thymeleaf templates. The asynchronous messaging is implemented with the help of RabbitMQ. In this sample implementation, the default H2 database is used as the in-memory store for demonstration purposes.

The code in this section demonstrates all the capabilities highlighted in the Reviewing the microservices capability model section of this chapter.

Implementation projects

The basic implementation of the BrownField Airline's PSS microservices system has five core projects as summarized in the following table. The table also shows the port range used for these projects to ensure consistency throughout the book:
