Error registering service to eureka server

Question

I am trying to register a client to spring-eureka-server, client deregisters just after registering

eureka-server logs:

Please let me know what could be possibly wrong.

Solution 1

Looks like a dependency issue.

If the app works fine (the core functionality) without eureka integration, then try changing the eureka-client dependency version.

Solution 2

Add

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

into Eureka and client app

It really works !!!

Solution 3

Eureka client deregisters when an app has been shutdown.

Check if there is any other reason why the app is stopping leading to eureka-client deregistering.

For my case, the application was shutting down due to spring-boot-starter-web dependency. After resolving this, the application started well.
