# ⚡ 快速参考 - 编译错误修复 - 2026-01-24

## 🎯 问题

后端编译报错: 找不到符号 `TimeCardController`

## ✅ 解决方案

**核心问题**: Controller不应该注入另一个Controller

### 修改的文件

1. **OrderController.java** - 移除TimeCardController依赖
2. **OrderServiceImpl.java** - 改用TimeCardService

### 快速验证

```bash
# 方式1: 运行验证脚本
cd peidu
🔍验证编译修复-2026-01-24.bat

# 方式2: 手动编译
cd peidu/backend
mvn clean compile -DskipTests
```

## 📋 修改详情

### OrderController.java
```java
// ❌ 删除
private final TimeCardController timeCardController;

// ✅ 保留
private final OrderService orderService;
private final TeacherOnlineService teacherOnlineService;
```

### OrderServiceImpl.java
```java
// ❌ 删除
import com.peidu.controller.TimeCardController;
private final TimeCardController timeCardController;

// ✅ 添加
import com.peidu.entity.TimeCard;
private final TimeCardService timeCardService;

// ✅ 修改调用方式
TimeCard updatedCard = timeCardService.deduct(
    cardId, hours, orderId, serviceName, teacherName, remark
);
```

## 🚀 预期结果

编译成功后应该看到:
```
[INFO] BUILD SUCCESS
[INFO] Total time: XX s
```

## 📝 架构原则

```
✅ 正确: Controller → Service → Mapper
❌ 错误: Controller → Controller
```
