This is a multi-module Maven project to simulate two microservices: product and order.
You can run them individually by running mvn spring-boot:run in each submodule.
Urls are: http://127.0.0.1:8080/product/1 and http://localhost:8081/order/1.
The provider submodule has a contract configuration that will generate the stub after testing/building. Check the generated file ContractVerifierTest after building the project.
The provider stub will be used in the integration test OrderIntegrationTest in the consumer submodule.
You may run mvn test on each submodule to see the tests running and the contract being fulfilled.
