Class CircuitBreakerAspect
java.lang.Object
io.github.resilience4j.circuitbreaker.configure.CircuitBreakerAspect
- All Implemented Interfaces:
org.springframework.core.Ordered
This Spring AOP aspect intercepts all methods which are annotated with a
CircuitBreaker
annotation. The aspect will handle methods that return a RxJava2 reactive type, Spring Reactor
reactive type, CompletionStage type, or value type.
The CircuitBreakerRegistry is used to retrieve an instance of a CircuitBreaker for a specific name.
Given a method like this:
@CircuitBreaker(name = "myService")
public String fancyName(String name) {
return "Sir Captain " + name;
}
each time the #fancyName(String)
method is invoked, the method's execution will pass
through a a CircuitBreaker
according to the given
config.
The fallbackMethod parameter signature must match either:
1) The method parameter signature on the annotated method or 2) The method parameter signature with a matching exception type as the last parameter on the annotated method
