In some applications, I saw people are using @EnableEurekaClient. And some other example applications are using @EnableDiscoveryClient.

Is there any difference between these two?

There are multiple implementations of "Discovery Service" (eureka, consul, zookeeper). @EnableDiscoveryClient lives in spring-cloud-commons and picks the implementation on the classpath. @EnableEurekaClient lives in spring-cloud-netflix and only works for eureka. If eureka is on your classpath, they are effectively the same.

    Question : Will both of above mentioned annotations enable Ribbon-enabled interceptor injected into RestTemplate? Any difference in behavior? I noticed that in previous Spring Cloud implementations `@LoadBalanced` was automatically applied, but in current version, it is required explicitly. Thank you. – fg78nc Jun 24 '18 at 22:48

    Yes. There is no difference. The load balanced annotation has been required for a long time. – spencergibb Jun 25 '18 at 02:43

    Why would someone want to use @EnableEurekaClient over the more general @EnableDisocveryClient? Wouldn't that bind them to the eureka implementation and make it harder to switch SD backends in the future? – Adam Hughes Jan 09 '19 at 18:20

    Yes. The only answer is if they want to be clear and enforce eureka. – spencergibb Jan 09 '19 at 21:03

Discovery service concept in spring cloud is implemented in different ways like Eureka, consul, zookeeper etc. If you are using Eureka by Netflix then @EnableEurekaClient is specifically for that. But if you are using any other service discovery including Eureka you can use @EnableDiscoveryClient.

In terms of its practicality and simplicity, if the registered center is eureka, then @EnableEurekaClient is recommended. If it is another registration center, @EnableDiscoveryClient is recommended.

@EnableEurekaCient will initilize the service discovery using eureka server, its like explicitly specifying to use EUREKA

While @EnableDiscovery Client will register dicovery service using the jar available in classpath like consul, Eureka, Kubernetes.

@EnableEurekaClient works only for Eureka if we use @EnableDiscoveryClient we can use any discovery client like Consul other than Eureka
