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

Documenting microservices


The traditional approach of API documentation is either to write service specification documents or to use static service registries. With a large number of microservices, it would be hard to keep the documentation of APIs in sync.

Microservices can be documented in many ways. This section will explore how microservices can be documented using the popular Swagger framework. In the following examples, we will use Springfox libraries for generating REST API documentation. Springfox is a set of Java Spring-friendly library.

Create a new Spring Starter project, and choose Web in the library selection window. Name the project as chapter3.swagger.

Note

The full source code of this example is available as the chapter3.swagger project in the code files of this book under the following Git repository:https://github.com/rajeshrv/Spring5Microservice

Since Springfox libraries are not part of the Spring suite, edit the pom.xml file, and add the springfox-swagger library dependencies...
