Class ReactiveCircuitBreakerAdapterDecorator

java.lang.Object
org.springframework.web.service.invoker.HttpExchangeAdapterDecorator
org.springframework.web.service.invoker.ReactorHttpExchangeAdapterDecorator
org.springframework.cloud.client.circuitbreaker.httpservice.ReactiveCircuitBreakerAdapterDecorator
All Implemented Interfaces:
org.springframework.web.service.invoker.HttpExchangeAdapter, org.springframework.web.service.invoker.ReactorHttpExchangeAdapter
public class ReactiveCircuitBreakerAdapterDecorator extends org.springframework.web.service.invoker.ReactorHttpExchangeAdapterDecorator
Reactive implementation of HttpExchangeAdapterDecorator that wraps @HttpExchange

In the event of a CircuitBreaker fallback, this class uses the user-provided fallback class to create a proxy. The fallback method is selected by matching either:

  • A method with the same name and argument types as the original method, or
  • A method with the same name and the original arguments preceded by a Throwable, allowing the user to access the cause of failure within the fallback.
Once a matching method is found, it is invoked to provide the fallback behavior. Both the fallback class and the fallback methods must be public.
