原因：

需要在FallBackFActory中添加 

@Component注解

 

@Component
@Slf4j
public class AAARemoteFallbackFactory implements FallbackFactory<AAARemote> {
    @Override
    public AAARemote create(Throwable cause) {
        return new AAARemote() {
            @Override
            public BizResponse<AAAResponse> getFunction(@RequestBody AAARequest request) {
                log.error("AAARemoteFallbackFactory  getAAARemote params:{} error:{}", JSON.toJSONString(request),JSON.toJSONString(cause.getMessage()));

                return new Response(ERROR.CODE);
            }

        };
    }
}
