A simple project following the microservice architecture with the objective of learn more about asynchronous and non-blocking programming with Java using the Reactor library along with how to implement microservices in a reactive way using Spring WebFlux.
-
webflux-demo: A simple demo application built with Spring Webflux, the application is unit-tested with the reactor-test libraryproduct-service: Microservice responsible for the management of products, connected to a MongoDB database through spring-boot-starter-data-mongodb-reactive library.user-service: Microservice responsible for the management of users, connected to a PostgresSQL database through spring-boot-starter-data-r2dbc library.order-service: Microservice responsible for the placement and management of orders, integrated to bothuser-serviceandproduct-serviceby HTTP calls and connected to a SQL Server database through Spring Data JPA.
If you have all databases installed on your system (MongoDB, PostgresSQL and SQL Server) then you can simply create the databases:
MongoDB: product-servicePostgresSQL: user-serviceSQL Server: order-service
Then just edit the credentials accordingly to the ones you have on yours databases
Demo application (http://localhost:8079)
./gradlew bootRunProduct service (http://localhost:8081)
./mvnw spring-boot:runUser service (http://localhost:8082)
./mvnw spring-boot:runOrder service (http://localhost:8080)
./mvnw spring-boot:runIf you have Docker installed on your system, then you can use docker-compose to run the microservice and the demo:
docker-compose -f ./docker-compose.microservices.yml up docker-compose -f ./docker-compose.demo.yml up
