Demo project for Spring Cloud Bus

Spring Cloud Bus Demo

This is a simple demonstration of Spring Cloud Bus feature of being able to refresh properties in all instances of an application

Start up RabbitMQ Server

rabbitmq-server

Start up Config Server

cd sample-config
mvn spring-boot:run

Start up Service instance 1

cd sample-service
mvn spring-boot:run

Start up Service instance 2

cd sample-service
mvn spring-boot:run -Dserver.port=8081

If all the applications have come up cleanly, the endpoint should be available at http://localhost:8080/show, http://localhost:8081/show

1. To change the property, open sample-config/src/main/resources/config/sample-service.yml and modify service.prop value and restart config server

2. The change will not reflect in the the applications

3. Now refresh the properties using a POST request:

curl -X POST http://localhost:8080/bus/refresh

1. The changed property should now reflect on all instances of the application.
