我的feignclient :

@FeignClient(value = "order-server", qualifiers = "order-server", fallback = OrderEcFallbackService.class)
public interface OrderEcService {
　　......省略
}

我的controller:

@RestController
@RequestMapping(value = "/driver/order/ec")
@PreAuthorize("isAuthenticated()")
@Api(tags = "司机快车订单相关接口")
public class DriverOrderEcController {
    @Qualifier("order-server")
    @Autowired
    private OrderEcService orderEcService;
    ......省略
}
启动时报错:

根据多方排查,代码没有问题,接口没有问题,

最后发现,问题在于feignclient的名字上面,

order服务的名字是: order-service,

我上面配置的是: order-server,

导致无法装配feignclient..

这问题也是醉了,完全想不到是这一块的问题,还是同事提醒一下我才发现.

主要是 之前可以启动,但是order-service的服务名称被改掉了,我这里没做相应的修改,所以报错了.
