Writing in the front
Microservices architecture is very popular nowadays, and building systems with microservices will also bring clearer business division and scalability. At the same time, there are a variety of technology stacks that support microservices, and Spring Cloud is a leader in these technologies.
As a new generation of service framework, The slogan of Spring Cloud is to develop “cloud-oriented applications”, which provides more comprehensive technical support for microservice architecture. It is also the flagship project of Spring, and can be integrated with other Spring projects such as Spring Framework, Spring Boot, Spring Data, Spring Batch, etc., which are critical for microservices.
The complete technical components of Spring Cloud:

Content abstract
This book provides a comprehensive and systematic introduction to Spring Cloud and its application to microservices architecture. The book consists of 13 chapters:
- Chapter 1 introduces basic concepts related to microservices architecture.
- Chapter 2 describes the components contained in Spring Cloud and the context of Spring Cloud conventions.
- Chapter 3 introduces the basics of Spring Cloud: SpringBoot, including how to build a SpringBoot service, SpringBoot configuration files and monitoring management endpoints provided by the Actuator.
- Chapters 4 through 13 cover Spring Cloud components in detail, Including Eureka (Service Registration and Discovery), OpenFeign (declaratively RESTful client), Hystrix (circuit breaker), Ribbon (client load balancer), Gateway (API Gateway), Config (configuration center), and Stream (message-driven), Bus (message Bus), Security (authentication and authorization), Sleuth (service link tracing).
This book provides a technical insight into the implementation of Spring Cloud components and further application ideas, which can be used as a reference book for microservice architecture practices using Spring Cloud.
Chapter 1 – Introduction to microservices Architecture
- The emergence of microservice architectures
- The genre of microservices architecture
- Cloud native and microservices
In recent years, microservice architecture has been one of the hot topics in the Internet technology circle. More and more Internet applications have adopted microservice architecture as the foundation of system construction. Many new technologies and concepts such as Docker, Kubernetes, DevOps, continuous delivery, ServiceMesh, etc. are also looking at, supporting, and following the evolution of microservices architecture.
This chapter will give an overview of microservices architecture, including how microservices architecture has evolved, the main schools of microservices architecture, and the relationship between the current mainstream cloud native applications and microservices.
Chapter 2 — Spring Cloud Overview
This chapter will provide an initial introduction to the SpringCloud architecture and related components, followed by an introduction to the SpringCloud context and SpringCloud’s common abstractions. This may occur in multiple components, so the introduction here is not dependent on specific components.
Chapter 3 — The foundation of Spring Cloud: SpringBoot
The first section of this chapter summarizes the functions and features of SpringBoot, including the core features of SpringBoot. Section 2 will set up a Spring Boot project to quickly understand the basic development process; The configuration files and applications of Spring Boot are summarized in section 3.
Chapter 4 — Service Registration and Discovery: Eureka
In this chapter, the first section will give a comprehensive overview of Eureka, and build a simple example of Eureka application to demonstrate the operation mechanism. In the second section, the overall architecture of Eureka is summarized from a macro perspective, and the behaviors among Eureka components and components are introduced. The third section will analyze the operating principle of EurekaClient from the perspective of source code and analyze the interaction between Eureka Server and EurekaClient. Section 4 will explain the source code of Euerka Server and analyze how it plays the role of service registry in microservices architecture. Section 5 covers configuration properties and advanced features in Eureka.
Chapter 5 — Declarative RESTful Clients: Spring Cloud OpenFeign
- The base application
- Source code analysis
- Advanced applications
In this chapter, the first section mainly explains the common ways of microservice interaction and the basic application of OpenFeign. The second section analyzes the source code of OpenFeign, respectively describes the dynamic registration of Spring instance definition (BeanDefinition), instance initialization and function call and network request three parts of the code implementation logic; The third section introduces the advanced uses of OpenFeign.
Chapter 6 — Circuit breakers: Hystrix
- The base application
- Hystrix principle
- The source code parsing
- Advanced applications
In the first section of this chapter, we will build a simple example to demonstrate Hystrix service disconnection. The second section introduces Hystrix terminology and design principles. The third section will analyze the implementation mechanism and operation principle of Hystrix from the perspective of source code. Section 4 covers configuration properties and advanced features in Hystrix.

- Load balancing
- The base application
- Source code analysis
- Advanced applications
The first section of this chapter mainly explains the concepts and implementation of load balancing. The second section shows some code examples of how to use the Ribbon. Section 3 introduces the Ribbon implementation principle and code details. Section 4 introduces advanced applications of the Ribbon.
Chapter 8 — API Gateway: Spring Cloud Gateway
- Introduction to Spring Cloud Gateway
- The base application
- The source code parsing
- Application of advanced
The first part of this chapter covers the features of the Spring Cloud Gateway; The second part is the basic application, explains the basic functions of SpringCloudGateway through gateway service and user service examples. The third part will explain the basic functions of Spring Cloud Gateway based on source code. Finally, the advanced learning of the Spring Cloud Gateway shows how to use the flow limiting mechanism and fuse downgrading features.
Chapter 9 — Configuration Center: Spring Cloud Config
- The base application
- The source code parsing
- Application of advanced
The first section of this chapter will implement a simple configuration center, including configuration server, client and Git repository, and introduce the main functions of microservice configuration center based on basic application cases.
