It supports highly available configurations like other service registries Eueka client, mainly handles the registration and discovery of services. The client service is embedded in the code of the client application by means of annotations and parameter configuration. The Eueka client registers its services wi

The final test area is the area where the unit test code is placed. After the project is established, we are ready to develop a small demo,hellowor
