Annotation Interface RateLimiter

@Retention(RUNTIME) @Target({METHOD,TYPE}) @Documented public @interface RateLimiter
This annotation can be applied to a class or a specific method. Applying it on a class is equivalent to applying it on all its public methods. The annotation enables throttling for all methods where it is applied. Throttling monitoring is performed via a rate limiter. See RateLimiter for details. If using Spring, name and fallbackMethod can be resolved using Spring Expression Language (SpEL).
