java.lang.IllegalStateException: Service id not legal hostname (/mall-coupon)

@FeignClient("/mall-coupon")
public interface CouponFeignService {
    @RequestMapping("/coupon/coupon/memberList")
    public String memberCouponList();
}

@FeignClient("/mall-coupon") 应该改为@FeignClient("mall-coupon")

@FeignClient("mall-coupon")
public interface CouponFeignService {
    @RequestMapping("/coupon/coupon/memberList")
    public String memberCouponList();
}
