In 2020, it is estimated that few friends do not know the pull of microservices
A microservice is an independent service application with a single responsibility. In the intellij idea tool, independent modules are developed with maven, specifically a small module developed with springboot, which handles a single professional business logic, and a module only does one thing.
Microservices emphasize the size of the service and focus on a certain point. The specific solution to a certain problem/a service application corresponding to the landing can be regarded as a module in the idea.
For example, if you go to the hospital: your teeth are uncomfortable, then you go to the dentistry. You have a headache, then you go to the brain department. Each department is a microservice, and a function is a service.
Many traditional enterprises are also gradually transforming to micro-service architecture. All that brings is that we programmers must also master the content of micro-services!
As I understand, Spring Cloud is a one-stop solution for microservice system architecture. In the process of building microservices, we need to do operations such as service discovery and registration , configuration center , message bus , load balancing , circuit breakers , data monitoring, etc. , And Spring Cloud provides us with a simple programming model that enables us to easily build microservice projects on the basis of Spring Boot.
Regarding microservices, I will not introduce too much. This article is mainly for students who want to learn which microservice technologies are not so esoteric!
The article is limited in length, if you need to get this PDF for learning, you can follow
Introduction
This book focuses on how to integrate the technology stack with Spring Cloud as the core to implement a complete system of microservice architecture. The book is roughly divided into three parts .
The first part (Chapters 1 to 4): Start with Spring Boot, and quickly build a weather forecast system with high concurrency capabilities and a friendly interface from 0 to 1.
Due to the excessive content of the document, only the catalog part is intercepted, and each knowledge point has more detailed content! !

The second part (Chapters 5 to 7): First analyze the pros and cons of the monolithic architecture, thereby introducing the concept of microservice architecture, and realizing the split of microservices from 1 to 0.
The third part (Chapters 8 to 16): Implement the governance of microservices by introducing the Spring Cloud technology stack, focusing on service registration and discovery, service communication, service consumption, load balancing, API gateway, centralized configuration, and container deployment , Log management, service fusing, automatic expansion, etc.
to sum up
The benefits of microservices
- Technology heterogeneity
- elasticity
- Scalability
- Simplify deployment
- Match the organizational structure
- Composability
- Optimization of fungibility
Nowadays Java programmers go for interviews. You say that you are not familiar with microservices. It is estimated that you don’t even have the opportunity to interview. Therefore, it is essential to master the technology of microservices. This document shared by the editor will lead you from a practical perspective. Principle, to the source code, to the actual combat, I believe you will learn something!
