java - Feign Hystrix 回退不起作用

Question

我有以下 FeignClient:

@FeignClient(name="FooMS",fallback=CustomerFeign.CustomerFeignImpl.class)
public interface CustomerFeign {

    @RequestMapping(value="/bar/{phoneNo}")
    List<Long> getFriends(@PathVariable("phoneNo") Long phoneNo);


    class CustomerFeignImpl implements CustomerFeign{

        @Override
        public List<Long> getFriends(Long phoneNo) {
            return new ArrayList<Long>(108);
        }

    }

}

当 FooMS 实例关闭时，我收到 500 错误，而不是执行回退。为什么会这样？

Answer 1

添加 @Component 和 feign.hystrix.enabled=true 效果很好
