Free Spring Boot Microservices Open Source Projects | GitHub | Download

Author:
In this article, I would like to suggest a few free open-source MicroServices projects developed using Spring Boot and Spring cloud for learning purposes. 

Spring Boot is the most popular and widely used Java framework for building MicroServices. 

Spring Cloud is a framework for building robust cloud applications. The framework facilitates the development of applications by providing solutions to many of the common problems faced when moving to a distributed environment.

Spring Cloud is essentially an implementation of various design patterns to be followed while building Cloud Native applications.

6. Microservices Demo Project

This is a sample project to demonstrates the most interesting features of the Spring Cloud Project for building microservice-based architecture. 

Architecture

This sample microservices-based system consists of the following modules:
  • gateway-service - a module that Spring Cloud Netflix Zuul for running Spring Boot application that acts as a proxy/gateway in our architecture.
  • config-service - a module that uses Spring Cloud Config Server for running configuration server in the native mode. The configuration files are placed on the classpath.
  • discovery-service - a module that depending on the example it uses Spring Cloud Netflix Eureka or Spring Cloud Netflix Alibaba Nacos as an embedded discovery server.
  • employee-service - a module containing the first of our sample microservices that allows us to perform CRUD operation on an in-memory repository of employees
  • department-service - a module containing the second of our sample microservices that allows to perform CRUD operation on an in-memory repository of departments. It communicates with employee-service.
  • organization-service - a module containing the third of sample microservices that allows us to perform CRUD operation on an in-memory repository of organizations. It communicates with both employee-service and organization-service.
The following picture illustrates the architecture described above:
