     * 1. CouponFeignService.saveSpuBouds(spuBoundTo);
     *      1) @RequestBody 将这个对象转为json
     *      2) 找到gulimall-coupon服务， 给/coupon/spubounds/save发送请求
     *         将上一步转的json放在请求体位置， 发送请求
     *      3) 对方服务收到请求， 请求体里有json数据.
     *          (@RequestBode SpuBoundsEntity spuBounds): 将请求体的json转为SpuBoundsEntity
     * 只要json数据模型是兼容的， 双方服务无需使用同一个To
     * @param spuBoundTo
     * @return
