`feignName` in this example refers to `@FeignClient` `value`, that is also aliased with `@FeignClient` `name` and `@FeignClient` `contextId`. In a load-balanced scenario, it also corresponds to the `serviceId` of the server app that will be used to retrieve the instances.
`feignName` in this example refers to `@FeignClient` `value`, that is also aliased with `@FeignClient` `name` and `@FeignClient` `contextId`. In a load-balanced scenario, it also corresponds to the `serviceId` of the server app that will be used to retrieve the instances. The specified classes for decoders, retryer and other ones must have a bean in the Spring context or have a default constructor.
Default configurations can be specified in the `@EnableFeignClients` attribute `defaultConfiguration` in a similar manner as described above. The difference is that this configuration will apply to _all_ feign clients.
