Here you can download zookeeper, open the folder, go to the bin directory, double-click zkServer.cmd to start (keep it in the boot state, you can put it aside)

First, package the interface project demo-interface into a jar package (packaging: Eclipse tool right-click the project maven install)

Then package the service provider project demo_provider as a jar package (packaging: Eclipse tool right-click the project maven install)

Find Provider.java for the demo_provider project and execute it in Java Application as follows

See here, it shows that the previous configuration is all right.
