Building Microservices with Spring

Overview of this book

Getting Started with Spring Microservices begins with an overview of the Spring Framework 5.0, its design patterns, and its guidelines that enable you to implement responsive microservices at scale. You will learn how to use GoF patterns in application design. You will understand the dependency injection pattern, which is the main principle behind the decoupling process of the Spring Framework and makes it easier to manage your code. Then, you will learn how to use proxy patterns in aspect-oriented programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. After understanding the basics, you will move on to more advanced topics, such as reactive streams and concurrency. Written to the latest specifications of Spring that focuses on Reactive Programming, the Learning Path teaches you how to build modern, internet-scale Java applications in no time. Next, you will understand how Spring Boot is used to deploying serverless autonomous services by removing the need to have a heavyweight application server. You’ll also explore ways to deploy your microservices to Docker and managing them with Mesos. By the end of this Learning Path, you will have the clarity and confidence for implementing microservices using Spring Framework. This Learning Path includes content from the following Packt products: • Spring 5 Microservices by Rajesh R V • Spring 5 Design Patterns by Dinesh Rajput

Implementing reactive with the Spring 5 Framework


The most highlighted feature of the latest version of the Spring Framework is the new reactive stack web framework. Reactive is the update that takes us to the future. This area of technology is gaining popularity with every passing day, which is the reason why Spring Framework 5.0 has been launched with the capability of reactive programming. This addition makes the latest version of the Spring Framework convenient for event-loop style processing, which enables scaling with a small number of threads.

The Spring 5 Framework implements the reactive programming pattern by using the reactor internally for its own reactive support. A reactor is a Reactive Stream implementation that extends the basic Reactive Streams. Twitter has been implemented as a reactive passed by using Reactive Streams.

Reactive Streams

Reactive Streams provide a protocol or rule for asynchronous stream processing with non-blocking back-pressure. This standard is also adopted...
