Spring Cloud Microservices Beginner Tutorial (9): Zuul Gateway Integrating Swagger2 for Auto-generated RESTful API Docs
In the previous section we covered Spring Cloud's API gateway Zuul. As service interfaces grow, we also need a tool to manage the interface documentation, so in this section I introduce Swagger. It is not part of the microservices architecture, but it is very practical, so I included it in the beginner tutorial. Swagger can not only visualize interfaces as documentation, but also test online and generate SDKs. This section mainly covers integrating Swagger; we won't go into Swagger usage in detail — I'll write a dedicated tutorial on that later.

Spring Cloud Microservices Beginner Tutorial (8): Spring Cloud Zuul API Gateway Dynamic Routing, Cookie Passing, and CORS
In the previous section we covered asynchronous communication between microservices via message queues. This section introduces the API gateway in microservices, Spring Cloud Zuul, which can centrally manage numerous interfaces and provide load balancing, among other functions.

Spring Cloud Microservices Beginner Tutorial (7): Spring Cloud Stream Message-driven Microservices
The previous section, 'Spring Cloud Microservices Beginner Tutorial (6): Spring Cloud BUS Message Bus for Dynamic Config Refresh,' already installed the RabbitMQ message queue and implemented the Spring Cloud Bus message bus. This section introduces Spring Cloud Stream message-driven microservices. You can use RabbitMQ, Apache Kafka, etc., for asynchronous message passing and receiving between microservices.

Spring Cloud Microservices Beginner Tutorial (6): Spring Cloud BUS Message Bus for Dynamic Config Refresh
The previous section, 'Spring Cloud Microservices Beginner Tutorial (5): Centralized Config — ConfigService,' implemented unified config management. At the end I mentioned that config is only pulled automatically after a restart, so this section explains using the Spring Cloud BUS message bus to automatically update config files, which lets the application hot-reload config without a restart.

Spring Cloud Microservices Beginner Tutorial (5): Centralized Config — ConfigService
In the previous section, 'Spring Cloud Microservices Beginner Tutorial (4): Inter-service Invocation — FeignClient,' we covered creating microservices and consuming between them. As the number of microservices grows, so do the many Spring Boot programs, and modifying their config files becomes a terrifying workload. So the microservices architecture also provides a config center, which lets us conveniently manage our service config files centrally. At the same time, the production environment config is not open to developers, so only operations staff need to maintain the online config center.

Spring Cloud Microservices Beginner Tutorial (4): Inter-service Invocation — FeignClient
In the previous section, 'Spring Cloud Microservices Beginner Tutorial (3): Service Registration,' we covered service registration. This section is about calls between services — acting as a service consumer to consume other services — and using FeignClient to call other services quickly and efficiently.

Spring Cloud Microservices Beginner Tutorial (3): Service Registration
In the previous section we covered 'Spring Cloud Microservices Beginner Tutorial (2): Service Registration and Discovery — Eureka,' which set up the microservices registry and discovery center. This section explains how to create a new microservice and register it with the registry.

Spring Cloud Microservices Beginner Tutorial (2): Service Registration and Discovery — Eureka
This section starts from scratch: we create a new Maven multi-module project and complete a basic demo of Spring Cloud Eureka-based service registration and discovery. The demo uses the IntelliJ IDEA development environment. Create a new Maven project in IntelliJ IDEA with JDK 1.8. I prefer manual operations, so first create an empty Maven project with groupId net.renfei, artifactId cloud, and version 1.0.0.

Spring Cloud Microservices Beginner Tutorial (1): Microservices Introduction
My personal blog site has always stuck to one major update per year, but this time I decided not to update it, because the next update would mean adopting microservices. Using a microservices architecture for a small site would be overkill, and it takes too much time and effort to maintain. So instead of rewriting my blog from scratch, I turned it into a tutorial series.
