The project is completed
Start the project
Before starting eureka-client, we first start the eureka-server built in the previous section. After both services are started, we visit the registration center and you can see:
It means that our service registration is successful! Visit http://127.0.0.1:8764/hi?name=hornet
At this point, the eureka-client (service discovery) project has been successfully built.
