Annotation Interface CircuitBreaker

@Retention(RUNTIME) @Target({METHOD,TYPE}) @Documented public @interface CircuitBreaker
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 backend monitoring for all methods where it is applied. Backend monitoring is performed via a circuit breaker. See CircuitBreaker for details. If using Spring, name and fallbackMethod can be resolved using Spring Expression Language (SpEL).
