Package io.github.resilience4j.bulkhead.configure

Class BulkheadAspect

java.lang.Object

io.github.resilience4j.bulkhead.configure.BulkheadAspect

All Implemented Interfaces:

org.springframework.core.Ordered

public class BulkheadAspect
extends Object
implements org.springframework.core.Ordered

This Spring AOP aspect intercepts all methods which are annotated with a Bulkhead annotation. The aspect will handle methods that return a RxJava2 reactive type, Spring Reactor reactive type, CompletionStage type, or value type.

The BulkheadRegistry is used to retrieve an instance of a Bulkhead for a specific name.

Given a method like this:

     @Bulkhead(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 Bulkhead 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
