Spring-Microservices

Microservices with Spring Boot.

Microservice architectures are the ‘new normal’. Building small, self-contained, ready to run applications can bring great flexibility and added resilience to your code. Spring Boot’s many purpose-built features make it easy to build and run your microservices in production at scale.

What are Microservices?

Microservices are a modern approach to software whereby application code is delivered in small, manageable pieces, independent of others.

Why build Microservices?

Their small scale and relative isolation can lead to many additional benefits, such as easier maintenance, improved productivity, greater fault tolerance, better business alignment, and more.

Microservices with Spring Boot:

With Spring Boot, your microservices can start small and iterate fast. That’s why it has become the de facto standard for Java™ microservices.

Microservice Example:

With DB:

How our architecture will look:

I will add more MS later for the MongoDB connection.

How to Run and Details:

This was built with JDK 19.

You always need to start the config-server first, then Eureka-server and then the api-gateway. Because eureka is our discovery service and the configuration server is our server that will provide us with the ports

Discovery Service

Name: Eureka-server;

Running at Port: 9010

Gateway Service

Name: Api-Gateway;

Running at Port: 9011

Microservices:

MS1 = MS-People-Controller

server.port = 0 (Eureka will decide the port)

MS2 = MS-Animals-Controller

server.port = 0 (Eureka will decide the port)

How to search

for example:

localhost:9011/ms-people-controller/api/people/status
