Method Details

mapping

@UnstableApi
public AbstractCircuitBreakerClientBuilder<I,O> mapping(CircuitBreakerMapping mapping)

Sets the CircuitBreakerMapping. If unspecified, CircuitBreakerMapping.ofDefault() will be used. Note that the CircuitBreakerClientHandler set by calling handler(CircuitBreakerClientHandler) will be overwritten by calling this method.

Returns:

this to support method chaining.

handler

@UnstableApi
public AbstractCircuitBreakerClientBuilder<I,O> handler(CircuitBreakerClientHandler handler)

Sets the CircuitBreakerClientHandler. Note that the CircuitBreakerMapping set by calling mapping(CircuitBreakerMapping) will be overwritten by calling this method.

Returns:

this to support method chaining.

recover

@UnstableApi
public AbstractCircuitBreakerClientBuilder<I,O> recover(BiFunction<? super ClientRequestContext,? super I,? extends O> fallback)

Sets the BiFunction. This is invoked when adding the fallback strategy.

For example:

 CircuitBreakerClient
   .builder(...)
   .recover((ctx, req) -> {
       // fallback logic
       return HttpResponse.of(...);
   });
 

Returns:

this to support method chaining.
