This example is a bare-bones microservices architecture built with Spring Boot, Spring Cloud, Eureka Server, and Zuul. See Java Microservices with Spring Boot and Spring Cloud to see how it was created.
Prerequisites: Java 11 and an internet connection.
To install this example, run the following commands:
git clone https://github.com/oktadev/java-microservices-examples.git
cd java-microservices-examples/spring-boot+cloudThe api-gateway and car-service projects are already pre-configured to be locked down with OAuth 2.0 and Okta. That means if you try to run them, you won't be able to login until you create an account, and an application in it.
Log in to your Okta Developer account (or sign up if you don't have an account).
- From the Applications page, choose Add Application.
- On the Create New Application page, select Web.
- Give your app a memorable name, add
http://localhost:8080/login/oauth2/code/oktaas a Login redirect URI, select Refresh Token (in addition to Authorization Code), and click Done.
Copy the issuer (found under API > Authorization Servers), client ID, and client secret into the application.properties of the api-gateway and car-service projects.
okta.oauth2.issuer=https://{yourOktaDomain}/oauth2/default
okta.oauth2.client-id=$clientId
okta.oauth2.client-secret=$clientSecretThen, run all the projects with ./mvnw in separate terminal windows. You should be able to navigate to http://localhost:8761 and see the apps have been registered with Eureka.
Then, navigate to http://localhost:8080/cool-cars in your browser, log in with Okta, and see the resulting JSON.
