# 🚀 Phase 3 快速启动 - 给下一个Agent
## 📊 当前状态(一句话)
**Application层12个模块已完成112个测试全部通过准备开始Controller迁移。**
---
## ✅ 我完成了什么
### 实现的模块12个
1. ✅ AuthApplication - JWT认证
2. ✅ ConfigApplication - 配置管理
3. ✅ ImportApplication - 账单导入
4. ✅ BudgetApplication - 预算管理
5. ✅ TransactionApplication - 交易+AI分类扩展15+方法)
6. ✅ EmailMessageApplication - 邮件管理
7. ✅ MessageRecordApplication - 消息管理
8. ✅ TransactionStatisticsApplication - 统计分析
9. ✅ TransactionPeriodicApplication - 周期账单
10. ✅ TransactionCategoryApplication - 分类+AI图标
11. ✅ JobApplication - 任务管理
12. ✅ NotificationApplication - 通知服务
### 代码统计
- **代码文件**: 29个 .cs 文件
- **测试数**: 112个100%通过)
- **编译状态**: ✅ 0警告 0错误

## 🎯 你需要做什么Phase 3
### 主要任务
**迁移12个Controller改为调用Application层预计10-12小时**
### 第一步集成准备30分钟
```bash
# 1. 重命名启用全局异常过滤器
mv WebApi/Filters/GlobalExceptionFilter.cs.pending WebApi/Filters/GlobalExceptionFilter.cs
# 2. 编辑 WebApi/WebApi.csproj确保有这行
<ProjectReference Include="..\Application\Application.csproj" />
# 3. 编辑 WebApi/Program.cs添加两处
# 3.1 修改AddControllers:
builder.Services.AddControllers(options =>
{
options.Filters.Add<GlobalExceptionFilter>();
});
# 3.2 添加Application服务注册:
builder.Services.AddApplicationServices();
# 4. 验证编译
dotnet build WebApi/WebApi.csproj
```
### 第二步Controller迁移按优先级
#### 迁移模板每个Controller都一样
```csharp
// 迁移前:
public class BudgetController(
IBudgetService budgetService, // ❌ 删除
IBudgetRepository budgetRepository, // ❌ 删除
ILogger<BudgetController> logger) : ControllerBase
{
[HttpGet]
public async Task<BaseResponse<List<BudgetResult>>> GetListAsync(...)
{
try // ❌ 删除try-catch
{
var result = await budgetService.GetListAsync(...);
return result.Ok();
}
catch (Exception ex)
{
logger.LogError(ex, "...");
return "...".Fail<List<BudgetResult>>();
}
}
private void ValidateRequest(...) { } // ❌ 删除私有验证方法
}
// 迁移后:
using Application.Budget; // ✅ 新增
using Application.Dto.Budget; // ✅ 新增
public class BudgetController(
IBudgetApplication budgetApplication, // ✅ 改为Application
ILogger<BudgetController> logger) : ControllerBase
{
[HttpGet]
public async Task<BaseResponse<List<BudgetResponse>>> GetListAsync(...)
{
// 全局异常过滤器会处理异常无需try-catch
var result = await budgetApplication.GetListAsync(...);
return result.Ok();
}
// 私有方法已删除迁移到Application
}
```
#### 迁移顺序(从易到难)
1. ConfigController → ConfigApplication15分钟
2. AuthController → AuthApplication15分钟
3. BillImportController → ImportApplication30分钟
4. BudgetController → BudgetApplication1小时
5. MessageRecordController → MessageRecordApplication30分钟
6. EmailMessageController → EmailMessageApplication1小时
7. **TransactionRecordController** → TransactionApplication2-3小时 复杂
8. TransactionStatisticsController1小时
9. 其他Controller2-3小时
### ⚠️ 特别注意TransactionRecordController的SSE流式响应
对于 `SmartClassifyAsync``AnalyzeBillAsync` 方法:
**✅ 保留在Controller**:
- Response.ContentType 设置
- Response.Headers 设置
- WriteEventAsync() 私有方法
- TrySetUnconfirmedAsync() 私有方法
**✅ 调用Application**:
```csharp
await _transactionApplication.SmartClassifyAsync(
request.TransactionIds.ToArray(),
async chunk => {
var (eventType, content) = chunk;
await TrySetUnconfirmedAsync(eventType, content);
await WriteEventAsync(eventType, content);
});
```

## 🧪 验证步骤
每迁移2-3个Controller后
```bash
# 1. 编译
dotnet build WebApi/WebApi.csproj
# 2. 运行测试
dotnet test WebApi.Test/WebApi.Test.csproj
# 3. 启动应用测试
dotnet run --project WebApi
# 访问 http://localhost:5000/scalar
```
