It is initialized in a `SmartLifecycle` (with `phase=0`), so the earliest you can rely on it being available is in another `SmartLifecycle` with a higher phase.

==== EurekaClient with Jersey
==== Underlying HTTP clients
`EurekaClient` uses either `RestTemplate`, `WebClient` or `JerseyClient` under the hood. In order to use the `EurekaClient`, you need to have one of the supported HTTP clients on your classpath.
To use `RestTemplate`, add `spring-boot-starter-web` to your dependencies. To use `WebClient`, add `spring-boot-starter-webflux` to your dependencies. If both `RestTemplate` and `WebClient` are on the classpath, when `eureka.client.webclient.enabled` is set to `true`, `WebClient` will be used. Otherwise, `RestTemplate` will be used.
By default, EurekaClient uses Spring's `RestTemplate` for HTTP communication.
If you wish to use Jersey instead, you need to add the Jersey dependencies to your classpath.
The following example shows the dependencies you need to add:
