public @interface EnableCacheServer

The EnableCacheServer annotation configures a Spring Configuration annotated class with a GemFire CacheServer bean in the Spring application context. This annotation is used in conjunction with the CacheServerApplication, or PeerCacheApplication annotations to add an additional CacheServers to a GemFire peer cache application configured with Spring (Data GemFire). To add more than 1 CacheServer to your application, this annotation can be nested in the EnableCacheServers annotation.
