|
||
将WebApi/Controllers中的Controller改造为调用Application层，实现架构分层。
|
||
|
||
### 预估工作量
|
||
- **总时间**: 8-12小时
|
||
- **难度**: 中等
|
||
- **风险**: 低（Application层已充分测试）
|
||
|
||

|
||
|
||
## 📋 Phase 3 详细步骤
|
||
|
||
### Step 1: 集成准备工作（30分钟）
|
||
|
||
#### 1.1 添加项目引用
|
||
|
||
**文件**: `WebApi/WebApi.csproj`
|
||
|
||
**操作**: 在 `<ItemGroup>` 中添加（如果不存在）：
|
||
```xml
|
||
<ProjectReference Include="..\Application\Application.csproj" />
|
||
```
|
||
|
||
**验证命令**:
|
||
```bash
|
||
dotnet build WebApi/WebApi.csproj
|
||
```
|
||
|
||
#### 1.2 启用全局异常过滤器
|
||
|
||
**操作**:
|
||
```bash
|
||
# 重命名文件以启用
|
||
mv WebApi/Filters/GlobalExceptionFilter.cs.pending WebApi/Filters/GlobalExceptionFilter.cs
|
||
```
|
||
|
||
#### 1.3 修改Program.cs
|
||
|
||
**文件**: `WebApi/Program.cs`
|
||
|
||
**修改点1**: 在 `builder.Services.AddControllers()` 处添加过滤器
|
||
```csharp
|
||
// 修改前:
|
||
builder.Services.AddControllers();
|
||
|
||
// 修改后:
|
||
builder.Services.AddControllers(options =>
|
||
{
|
||
options.Filters.Add<GlobalExceptionFilter>();
|
||
});
|
||
```
|
||
|
||
**修改点2**: 注册Application服务（在现有服务注册之后）
|
||
```csharp
|
||
// 在 builder.Services.AddScoped... 等服务注册之后添加
|
||
builder.Services.AddApplicationServices();
|
||
```
|
||
|
||
**验证命令**:
|
||
```bash
|
||
dotnet build WebApi/WebApi.csproj
|
||
dotnet run --project WebApi
|
||
# 访问 http://localhost:5000/scalar 验证API文档
|
||
```
|
||
|

|
||
|
||
### Step 3: Controller迁移标准模板
|
||
|
||
#### 迁移前代码示例（BudgetController）:
|
||
```csharp
|
||
public class BudgetController(
|
||
IBudgetService budgetService,
|
||
IBudgetRepository budgetRepository,
|
||
ILogger<BudgetController> logger) : ControllerBase
|
||
{
|
||
[HttpGet]
|
||
public async Task<BaseResponse<List<BudgetResult>>> GetListAsync([FromQuery] DateTime referenceDate)
|
||
{
|
||
try
|
||
{
|
||
return (await budgetService.GetListAsync(referenceDate))
|
||
.OrderByDescending(b => b.IsMandatoryExpense)
|
||
.ThenBy(b => b.Category)
|
||
.ToList()
|
||
.Ok();
|
||
}
|
||
catch (Exception ex)
|
||
{
|
||
logger.LogError(ex, "获取预算列表失败");
|
||
return $"获取预算列表失败: {ex.Message}".Fail<List<BudgetResult>>();
|
||
}
|
||
}
|
||
|
||
// ... 其他方法 + 私有验证逻辑（30行）
|
||
}
|
||
```
|
||
|
||
#### 迁移后代码示例:
|
||
```csharp
|
||
public class BudgetController(
|
||
IBudgetApplication budgetApplication, // 改为注入Application
|
||
ILogger<BudgetController> logger) : ControllerBase
|
||
{
|
||
[HttpGet]
|
||
public async Task<BaseResponse<List<BudgetResponse>>> GetListAsync(
|
||
[FromQuery] DateTime referenceDate)
|
||
{
|
||
// 全局异常过滤器会捕获异常，无需try-catch
|
||
var result = await budgetApplication.GetListAsync(referenceDate);
|
||
return result.Ok();
|
||
}
|
||
|
||
// 删除私有方法（已迁移到Application）
|
||
}
|
||
```
|
||
|
||
#### 迁移步骤（每个Controller）:
|
||
|
||
**1. 修改构造函数**
|
||
- ✅ 移除: `IXxxService`, `IXxxRepository`
|
||
- ✅ 添加: `IXxxApplication`
|
||
- ✅ 保留: `ILogger<XxxController>`
|
||
|
||
**2. 简化Action方法**
|
||
- ✅ 移除 try-catch 块（交给全局过滤器）
|
||
- ✅ 调用 Application 方法
|
||
- ✅ 返回 `.Ok()` 包装
|
||
|
||
**3. 更新DTO引用**
|
||
- ✅ 从: `using WebApi.Controllers.Dto;`
|
||
- ✅ 改为: `using Application.Dto.Budget;` 等
|
||
|
||
**4. 删除私有方法**
|
||
- ✅ 业务验证逻辑已迁移到Application
|
||
|
||
**5. 更新DTO类型**
|
||
- ✅ 从: `CreateBudgetDto` → `CreateBudgetRequest`
|
||
- ✅ 从: `BudgetResult` → `BudgetResponse`
|
||
|
||
**6. 测试验证**
|
||
```bash
|
||
dotnet build WebApi/WebApi.csproj
|
||
dotnet test --filter "FullyQualifiedName~BudgetController"
|
||
dotnet run --project WebApi
|
||
```
|
||
|
||
---
|
||
|
||
### Step 4: 特殊处理 - TransactionRecordController
|
||
|
||
#### 流式响应（SSE）特殊处理
|
||
|
||
**SmartClassifyAsync** 和 **AnalyzeBillAsync** 使用 Server-Sent Events：
|
||
|
||
**Controller保留SSE逻辑**:
|
||
```csharp
|
||
[HttpPost]
|
||
public async Task SmartClassifyAsync([FromBody] SmartClassifyRequest request)
|
||
{
|
||
// SSE响应头设置（保留在Controller）
|
||
Response.ContentType = "text/event-stream";
|
||
Response.Headers.Append("Cache-Control", "no-cache");
|
||
Response.Headers.Append("Connection", "keep-alive");
|
||
|
||
// 验证账单ID列表
|
||
if (request.TransactionIds == null || request.TransactionIds.Count == 0)
|
||
{
|
||
await WriteEventAsync("error", "请提供要分类的账单ID");
|
||
return;
|
||
}
|
||
|
||
// 调用Application，传递回调
|
||
await _transactionApplication.SmartClassifyAsync(
|
||
request.TransactionIds.ToArray(),
|
||
async chunk =>
|
||
{
|
||
var (eventType, content) = chunk;
|
||
await TrySetUnconfirmedAsync(eventType, content); // Controller专属逻辑
|
||
await WriteEventAsync(eventType, content);
|
||
});
|
||
|
||
await Response.Body.FlushAsync();
|
||
}
|
||
|
||
private async Task WriteEventAsync(string eventType, string data)
|
||
{
|
||
var message = $"event: {eventType}\ndata: {data}\n\n";
|
||
await Response.WriteAsync(message);
|
||
await Response.Body.FlushAsync();
|
||
}
|
||
|
||
private async Task TrySetUnconfirmedAsync(string eventType, string content)
|
||
{
|
||
// 解析AI返回的JSON并更新交易记录的UnconfirmedClassify字段
|
||
// 这部分逻辑保留在Controller（与HTTP响应紧密耦合）
|
||
}
|
||
```
|
||
|
||
**Application接口**:
|
||
```csharp
|
||
// Application/Transaction/TransactionApplication.cs
|
||
Task SmartClassifyAsync(long[] transactionIds, Action<(string type, string data)> onChunk);
|
||
Task AnalyzeBillAsync(string userInput, Action<string> onChunk);
|
||
```

|
||
|
||
**方法迁移表**:
|
||
|
||
| Controller方法 | Application方法 | 特殊处理 |
|
||
|---------------|----------------|----------|

|
||
| **SmartClassifyAsync** | SmartClassifyAsync | ⚠️ **SSE流式** |
|
||
| **AnalyzeBillAsync** | AnalyzeBillAsync | ⚠️ **SSE流式** |
|
||
|
||
**⚠️ 特殊处理: SSE流式响应方法**
|
||
|
||
对于 `SmartClassifyAsync` 和 `AnalyzeBillAsync`：
|
||
1. **保留Controller中的SSE响应头设置**
|
||
2. **保留 WriteEventAsync 私有方法**
|
||
3. **保留 TrySetUnconfirmedAsync 私有方法**
|
||
4. **Application提供回调接口**
|
||
|
||
**示例代码**（参考上面 Step 4 的详细说明）
|
||
|
||
**using更新**:
|
||
```csharp
|
||
using Application.Transaction;
|
||
using Application.Dto.Transaction;
|
||
```
|

|
||
|
||
### 8️⃣ TransactionStatisticsController
|
||
|
||
**文件**: `WebApi/Controllers/TransactionStatisticsController.cs`
|
||
|
||
**当前依赖**:
|
||
```csharp
|
||
public class TransactionStatisticsController(
|
||
ITransactionRecordRepository transactionRepository,
|
||
ITransactionStatisticsService transactionStatisticsService,
|
||
ILogger<TransactionStatisticsController> logger,
|
||
IConfigService configService)
|
||
```
|
||
|
||
**迁移后**:
|
||
```csharp
|
||
public class TransactionStatisticsController(
|
||
ITransactionStatisticsApplication statisticsApplication,
|
||
ILogger<TransactionStatisticsController> logger)
|
||
```
|
||
|
||
**方法迁移**:
|
||
- `GetBalanceStatisticsAsync(year, month)` → `_statisticsApplication.GetBalanceStatisticsAsync(year, month)`
|
||
- `GetDailyStatisticsAsync(year, month)` → `_statisticsApplication.GetDailyStatisticsAsync(year, month)`
|
||
- `GetWeeklyStatisticsAsync(start, end)` → `_statisticsApplication.GetWeeklyStatisticsAsync(start, end)`
|
||
|
||
**using更新**:
|
||
```csharp
|
||
using Application.Statistics;
|
||
using Application.Dto.Statistics;
|
||
```
|
||
|
||
---
|
||
|
||
### 9️⃣ - 1️⃣2️⃣ 其他Controller（参考前面模板）
|
||
|
||
按照相同的模式迁移：
|
||
- NotificationController → NotificationApplication
|
||
- TransactionPeriodicController → TransactionPeriodicApplication
|
||
- TransactionCategoryController → TransactionCategoryApplication
|
||
- JobController → JobApplication
|
||
|
||

|
||
|
||
## 🧪 验证检查清单
|
||
|
||
### 每个Controller迁移后的验证步骤
|
||
|
||
```bash
|
||
# 1. 编译验证
|
||
dotnet build WebApi/WebApi.csproj
|
||
|
||
# 2. 运行所有测试
|
||
dotnet test WebApi.Test/WebApi.Test.csproj
|
||
|
||
# 3. 启动应用
|
||
dotnet run --project WebApi
|
||
|
||
# 4. 访问API文档验证接口
|
||
# http://localhost:5000/scalar
|
||
|
||
# 5. 手动功能测试（可选）
|
||
# - 登录
|
||
# - 创建预算
|
||
# - 导入账单
|
||
# - 查询交易记录
|
||
```
|
||
|
||

|
||
|
||
## 🚨 已知问题与注意事项
|
||
|
||
### 1. DTO类型映射差异
|
||
|
||
**BudgetController**:
|
||
- `BudgetResult.SelectedCategories` 是 `string[]`（不是string）
|
||
- `BudgetResult.StartDate` 是 `string`（不是DateTime）
|
||
- 在 `BudgetApplication.MapToResponse` 中已处理转换
|
||
|
||
### 2. 流式响应（SSE）不要完全迁移
|
||
|
||
**保留在Controller**:
|
||
- Response.ContentType 设置
|
||
- Response.Headers 设置
|
||
- WriteEventAsync 方法
|
||
- TrySetUnconfirmedAsync 方法
|
||
|
||
**迁移到Application**:
|
||
- 业务逻辑
|
||
- 数据验证
|
||
- Service调用
|
||
|
||
### 3. 全局异常过滤器注意事项
|
||
|
||
**会自动处理的异常**:
|
||
- `ValidationException` → 400 Bad Request
|
||
- `NotFoundException` → 404 Not Found
|
||
- `BusinessException` → 500 Internal Server Error
|
||
- 其他 `Exception` → 500 Internal Server Error
|
||
|
||
**不会处理的场景**:
|
||
- 流式响应（SSE）中的异常需要手动处理
|
||
- 文件下载等特殊响应

## 📈 预期收益
|
||
|
||
### 代码质量改进
|
||
|
||
| Controller | 迁移前行数 | 预计迁移后 | 代码减少 |
|
||
|-----------|-----------|-----------|---------|
|
||
| BudgetController | 238行 | ~80行 | ⬇️ 66% |
|
||
| TransactionRecordController | 614行 | ~200行 | ⬇️ 67% |
|
||
| AuthController | 78行 | ~30行 | ⬇️ 62% |
|
||
| ConfigController | 41行 | ~20行 | ⬇️ 51% |
|
||
| BillImportController | 82行 | ~35行 | ⬇️ 57% |
|
||
|
||
**总体代码减少**: 预计 **60-70%**
|
||
|
||
### 架构清晰度
|
||
|
||
**迁移前**:
|
||
```
|
||
Controller → Service/Repository (职责混乱)
|
||
↓
|
||
业务逻辑分散
|
||
```
|
||
|
||
**迁移后**:
|
||
```
|
||
Controller → Application → Service
|
||
(路由) (业务逻辑) (领域逻辑)
|
||
↓
|
||
Repository
|
||
(数据访问)
|
||
```

## 🔄 迁移策略建议
|
||
|
||
### 策略1: 渐进式迁移（推荐）⭐
|
||
|
||
**优点**: 风险低，可随时回滚，边迁移边验证
|
||
|
||
**步骤**:
|
||
1. 先迁移简单Controller（Config, Auth）验证架构
|
||
2. 迁移中等复杂Controller（Budget, Import）
|
||
3. 最后迁移复杂Controller（Transaction）
|
||
|
||
**验证节点**:
|
||
- 每迁移1-2个Controller后运行测试
|
||
- 每个阶段手动验证核心功能
|
||
|
||
### 策略2: 批量迁移
|
||
|
||
**优点**: 快速完成，一次性到位
|
||
|
||
**步骤**:
|
||
1. 一次性修改所有Controller
|
||
2. 统一编译和测试
|
||
3. 集中解决问题
|
||
|
||
**风险**: 如果出现问题难以定位
