        return data;
  }

feign

    @PostMapping(value = "/api/order/getProviderByPost")
    List<OrderInfo> getProviderByPost(@RequestBody OrderInfo info);

普通表单参数

生产者

 @GetMapping("/getProviderByGet")
 @ApiOperation(value = "provider-普通表单参数")
 public List<OrderInfo> getOrderInfo(String  addressInfo) {

        List<OrderInfo> data = iOrderService.getOrderInfoByPostTwo(addressInfo);
        return data;
 }
