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

Summary


In this chapter, we learned how to scale Twelve-Factor Spring Boot microservices using the Spring Cloud project. Our learnings were applied on the BrownField Airline's PSS microservice, which we developed in the previous chapter.

We explored the Spring Config Server for externalizing microservices configurations, and how to deploy the Config Server for high availability. We also learned Eureka for load balancing, dynamic service registration, and discovery. Implementation of an API Gateway was examined by implementing Zuul. Finally, we concluded with the reactive style integration of microservices using Spring Cloud Streams.

The BrownField Airline's PSS microservices are now deployable for Internet scale. Other Spring Cloud components such as Hyterix, Sleuth, and others will be covered in the next chapter.
