我正在使用 Resilience4j 断路器版本：'1.4.0 和 Spring boot 版本 2.0.6，我的问题是 - 回退方法不起作用。该调用不会转到后备方法。下面是我的代码：

@Override
@CircuitBreaker(name="mainService",fallbackMethod = "callFallback")
public JSONObject callService(JSONObject rawRequest) throws TimeoutException {
      ...
       throw new TimeoutException("Time occured while calling 
       service");
      ...
}

-- 和后备方法：

private JSONObject callFallback(JSONObject rawRequest,Throwable t){

    System.out.println("Inside fallback method callNsFallback, 
        cause"+t.toString());

        logger.info("Inside fallback method callFallback, 
        cause - {}",t.toString());

    return rawRequest;
}

--application.yml中的配置
