SpringBootMicroservicesWithDiscoveryGatewayConfig

Example project of Spring Boot Microservices with the following services School and Student, additionally there is Eureka Discovery Service, API Gateway and Config Server, and Hystrix Circuti Breaker

• Updated with SpringDoc and Postman test collection

Circuit breaker: it monitors connections to services and falls back if the connection (service) is down

Additional steps to without Config server: Git repo config-server with application.properties files containing the following common configuration for services:

eureka.client.register-with-eureka=true eureka.client.fetch-registry=true eureka.client.service-url.defaultZone=http://localhost:8761/eureka/ eureka.client.instance.hostname=localhost

Then bootstrap.properties added to the services (student, school, gateway), as it is called first, before application.properties. It contains: spring.cloud.config.enabled=true spring.cloud.config.uri=http://localhost:8083 (this is the cloud-config-server address)

Try it out:

Postman collection updated, so you can load it into Postman and run.

Manually in browser:

With Postman for example: Post: http://localhost:8099/schools/ Body: { "id":"1", "name":"School1" }

Get: http://localhost:8099/schools/1 This will give back the school 1 { id: 1, name: "School1"}

Post: http://localhost:8099/students/ Body: { "id":"1", "name":"Joe", "schoolId":"1" }

Get: http://localhost:8099/students/1 This will give back the student 1 with the related school { "student": { "id": 1, "name": "Joe", "schoolId": 1 }, "school": { "id": 1, "name": "School1" } }
