# fix(order-v2): 早鸟优惠接口字段名对齐前端(保存不再报"不能为空")
|
||
|
||
> **服务**: hl-order-service-v2
|
||
> **PR**: #911
|
||
> **Issue**: #910
|
||
> **日期**: 2026-04-19
|
||
> **前端是否需要改动**: **无需改动**(后端 VO 字段名已对齐前端现有调用)
|
||
|
||
---
|
||
|
||
## 现象
|
||
早鸟优惠计划管理页(`/order/early-bird`)新增/编辑计划填完所有字段点提交,后端报:
|
||
```
|
||
name: 计划名称不能为空; discountPerPerson: 优惠金额不能为空
|
||
```
|
||
|
||
## 根因
|
||
后端 VO 字段名和前端、Entity、DB 列三方都不一致:
|
||
|
||
| UI 标签 | 前端字段 | 旧后端 VO | Entity/DB |
|
||
|--------|---------|-----------|-----------|
|
||
| 计划名称 | `planName` | `name` ❌ | `plan_name` |
|
||
| 优惠金额 | `discountAmount` | `discountPerPerson` ❌ | `discount_amount` |
|
||
| 备注 | `remark` | `description` ❌ | `remark` |
|
||
|
||
**只有后端 VO 是"异类"**,前端、Entity、DB 都用 `planName/discountAmount/remark`。
|
||
|
||
## 修复
|
||
|
||
### 受影响接口(请求/响应结构变化)
|
||
|
||
| 方法 | 路径 | 变更 |
|
||
|------|------|------|
|
||
| POST | `/admin/order/early-bird` | Request body 字段改名 |
|
||
| PUT | `/admin/order/early-bird/{id}` | 同上 |
|
||
| GET | `/admin/order/early-bird/{id}` | Response body 字段改名 |
|
||
| GET | `/admin/order/early-bird` | Response records 字段改名 |
|
||
|
||
### 字段映射
|
||
|
||
| 旧字段(已废弃)| 新字段(正在用) |
|
||
|---------------|----------------|
|
||
| `name` | `planName` |
|
||
| `discountPerPerson` | `discountAmount` |
|
||
| `description` | `remark` |
|
||
| `productType`(Request+Response) | **已删除**(0 调用僵尸字段) |
|
||
|
||
## 前端行动项
|
||
|
||
**无需改动**。前端本来就传 `planName/discountAmount/remark`(后端之前用错字段名才导致 bug)。
|
||
|
||
## 测试环境验证
|
||
|
||
```bash
|
||
POST /admin/order/early-bird
|
||
body: {"planName":"默认早鸟优惠","discountAmount":100.00,"minPeople":1,"startDate":"2026-04-01","endDate":"2026-05-31","remark":"测试"}
|
||
|
||
响应:
|
||
{"code":200,"data":{"planId":"...","planName":"默认早鸟优惠","discountAmount":100.0,"remark":"测试",...}}
|
||
```
|
||
|
||
反向验证(不传 planName):
|
||
```
|
||
错误消息: "planName: 计划名称不能为空"(字段名正确反映前端字段)
|
||
```
