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

Spring Web reactive module

As of Spring 5.0 Framework, Spring has introduced a new module for reactive programming--the spring-web-reactive module. It is based on Reactive Streams. Basically, this module uses the Spring MVC module with reactive programming, so, you can still use the Spring MVC module for your web application either separately or with the spring-web-reactive module.

This new module in the Spring 5.0 Framework contains support for the Reactive-web-functional- based programming model. It also supports the Annotation-based programming model. The Spring-web-reactive module contains support for reactive HTTP and WebSocket clients to call the reactive server application. It also enables the reactive web client to make a connection with a reactive HTTP connection with a reactive web application.

The following diagram shows a Spring-web-reactive module with its components that give reactive behavior to the Spring web application:

As you can see in the preceding diagram, there are two...
