Application. properties

server.port=8764eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/spring.application.name=service-say

The project has been established.

Start the project

Before starting eureka-client, we first start the eureka-server set up in the previous section. After both services are started, we access the registration center. We can see that:

This indicates that our service has been registered successfully! Visit http: // 127.0.0.1: 8764/hi? Name = hornet

At this point, the eureka-client (service discovery) project has been set up successfully.
