Today’s interconnected applications have more complex services, higher user access, and faster development and iteration requirements. Landing microservice architecture has become the most common practice in the industry, but it also introduces system complexity. It is necessary to solve too many service instances and service call relationships. Typical problems such as clutter and too long service call links. The Spring Cloud framework based on Spring Boot solves the above problems well. Whether in corporate interviews or actual development, Spring Cloud has become one of the necessary skills for back-end engineers.
Spring Cloud learning map (abbreviated version)
However, driven by the first-line manufacturers, from the previous familiarity with Spring Cloud from the bonus item, it has now become a must-have item, making microservices Java a must-have test point for programmer interviews. Whether programmers with Spring Cloud technical capabilities are among them is also one of the core elements that affect salary in corporate recruitment.
Spring Cloud is not a complicated technology, many developers can quickly get started. But it is simple and easy to understand, but developers can easily ignore the underlying technology behind annotations. In the process of interviews and actual architecture, superficial understanding of technology and lack of details have become fatal injuries for countless developers. Recently, I have compiled and collected the SpringCloud basics to the actual bottom learning manual. The above practical problems are very thorough, and I will share with you today. Due to space reasons, this article only shows the catalog and content screenshots. Those who need to learn RocketMQ actual combat to the source code manual can get it for free by adding an assistant after clicking like it!
SpringCloud actual combat to the introduction to the principle manual
These modules are the introduction to Spring Cloud . They mainly introduce the common modules of Spring Cloud, including service discovery, service registration, configuration center, link tracking, exception handling and case building! The main contents of this section are as follows:
SpringCloud actual combat to principle manual-Eureka
Eureka is a very important core module in Spring Cloud. Using Spring Cloud is inseparable from Eureka. We use the acquisition of Promotion information and all product functions in a product service as an example to let everyone quickly understand what Eureka is used for, and how to use. The main contents of this section are as follows:
SpringCloud actual combat to principle manual-Ribbon
Load balancing is usually divided into hard load and soft load, and soft load is divided into client load balancing and server load balancing. Ribbon is a client-side load balancing framework and one of the core components of Spring Cloud. Spring Cloud uses Ribbon to achieve load balancing between services. The main contents of this section are as follows:
SpringCloud actual combat to principle manual-Feign
This module leads you to thoroughly understand the remote service call in Spring Cloud-Feign. It is a process of remote service invocation based on HTTP protocol. Conveniently and quickly help us realize the call between services. Let's learn more about Feign from usage to source code. The main contents of this section are as follows:
SpringCloud actual combat to principle manual-Hystrix
Hystrix is an open source component of Netflix. Compared with the aforementioned Ribbon and Feign, Hystrix is much more complicated. Before Hystrix came out, everyone might have no idea about "fuse", what is "fuse", why do we need "fuse", and what needs to be done with "fuse", let us see how Hystrix does it. Hystrix is implemented based on RxJava, and the source code is difficult to read. This article explains the principles with examples, analyzes the key implementation codes, and shows you the mysteries of Hystrix. The main contents of this section are as follows:
SpringCloud actual combat to principle manual-gateway concept
SpringCloud actual combat to principle manual-GateWay
Since the abortion of Zuul 2.0, Spring has officially created Spring Cloud Gateway, the next-generation service gateway based on Spring WebFlux, which is known as high-performance and easy to use. As the technology has reached the production level. The requirements for Spring Cloud Gateway have also become complicated: dynamic routing, unified authentication, etc. The main contents of this section are as follows:
SpringCloud actual combat to principle manual-Apollo
This module introduces the Apollo Configuration Center. It has the advantages of real-time effect, support for grayscale release, sub-environment, sub-cluster management configuration, and perfect authority management. Using Apollo can make complex and messy configuration simple and clear, simple maintenance, and upgrade Convenience.

to sum up
This study notes manual is mainly divided into the following:
- The first module foundation chapter introduces the basic elements and technical system of the microservice architecture, and formally introduces the Spring Cloud open source framework and its functional characteristics. There is no barrier to entry for novices.
- Modules 2～6: Service governance, API gateway, service fault tolerance, configuration center, event-driven architecture . The explanation of these basic components and mainstream microservice technology systems will take you to think about how to build microservices based on a complete set of microservice solutions. service system.
- Modules 7 to 9: service access security, link tracking, microservice testing : the explanation of these Spring Cloud core functional modules makes this microservice architecture technical system more complete and more comprehensive.
If you are already using the Spring Cloud framework: The content of this learning manual can help you solve some practical problems. Through the analysis of the framework principle, you can improve your theoretical level and architecture design ability, so that you can deal with interviews and job promotions.
