# 互换模块独立化最终实施方案
|
||
|
||
## 一、项目现状分析
|
||
|
||
### 1.1 技术架构特征
|
||
- **传统ASP.NET Core MVC**：基于Razor视图引擎的服务端渲染
|
||
- **jQuery+Bootstrap前端**：经典的Web表单交互模式
|
||
- **单体应用结构**：所有功能模块紧密耦合在同一应用中
|
||
- **共享数据库**：统一的数据存储和访问层
|
||
|
||
### 1.2 互换模块现状
|
||
```
|
||
互换相关组件：
|
||
├── Controllers (SwapTrade2Controller.cs - 现有主要控制器)
|
||
├── Views (40+个.cshtml文件，包括复杂表单和报表)
|
||
├── JavaScript (大量业务逻辑嵌入在页面脚本中)
|
||
├── Business Logic (SwapModule业务服务层)
|
||
└── Data Access (直接使用主应用DbContext)
|
||
|
||
表结构现状：
|
||
❌ 已废弃的老互换表：
|
||
├── trade_swap（互换交易主表）
|
||
├── trade_swap_flow（互换交易流水表）
|
||
└── trade_swap_flow_more（互换交易流水扩展表）
|
||
|
||
✅ 当前使用的现代化表结构：
|
||
├── trade（通用交易表，包含收益互换类型）
|
||
├── swap_flow（互换流水明细表）
|
||
├── swap_position（互换持仓表）
|
||
├── swap_flow_event（互换流水事件表）
|
||
├── swap_flow_merge（互换流水合并表）
|
||
├── swap_event（互换事件表）
|
||
├── eod_swap（互换日终表）
|
||
└── eod_swap_position（互换日终持仓归档表）
|
||
```
|
||
|
||
## 二、最终方案设计
|
||
|
||
### 2.1 核心架构原则
|
||
✅ **完全舍弃老表结构** - 不再使用trade_swap系列废弃表
|
||
✅ **基于新架构开发** - 围绕trade和swap_position等现代表构建
|
||
✅ **前端零改动** - 保持所有.cshtml页面和JavaScript逻辑不变
|
||
✅ **后端独立化** - 互换业务逻辑抽取为独立API服务
|
||
✅ **共享数据库** - 继续使用现有数据库，避免数据迁移风险
|
||
✅ **无感知切换** - 用户体验完全一致，业务连续性100%
|
||
|
||
### 2.2 最终架构图
|
||
```

|
||
|
||
## 三、技术选型与实现
|
||
|
||
### 3.1 YARP反向代理配置（推荐）
|
||
|
||
#### 为什么选择YARP？
|
||
✅ **.NET原生** - 与现有技术栈完美契合
|
||
✅ **高性能** - 比Nginx/Ocelot更好的性能表现
|
||
✅ **灵活路由** - 支持复杂的路由匹配和转换规则
|
||
✅ **易于维护** - 统一的.NET生态系统管理
|
||
|
||
#### YARP配置示例
|
||
```csharp
|
||
// Program.cs - YARP代理配置
|
||
var builder = WebApplication.CreateBuilder(args);
|
||
|
||
// 添加YARP反向代理
|
||
builder.Services.AddReverseProxy()
|
||
.LoadFromConfig(builder.Configuration.GetSection("ReverseProxy"));
|
||
|
||
var app = builder.Build();
|
||
|
||
// 配置路由转发规则
|
||
app.MapReverseProxy(proxyPipeline =>
|
||
{
|
||
// 互换API路由 - 转发到独立服务
|
||
proxyPipeline.UseWhen(context =>
|
||
context.Request.Path.StartsWithSegments("/api/swap"),
|
||
handler =>
|
||
{
|
||
handler.UseMiddleware<AuthenticationMiddleware>(); // 认证前置
|
||
handler.UseSessionAffinity(); // 会话亲和性
|
||
});
|
||
|
||
// 前端页面路由 - 保持原有处理
|
||
proxyPipeline.UseWhen(context =>
|
||
context.Request.Path.StartsWithSegments("/swaptrade") ||
|
||
context.Request.Path.StartsWithSegments("/swaptrade2"),
|
||
handler =>
|
||
{
|
||
// 原有ASP.NET Core MVC处理逻辑
|
||
});
|
||
});
|
||
|
||
app.Run();
|
||
```
|
||
|
||
#### appsettings.json配置
|
||
```json

### 3.3 前端无感知适配
|
||
|
||
#### JavaScript调用自动转发
|
||
```javascript
|
||
// 前端调用保持原有方式不变
|
||
function createSwapTrade(formData) {
|
||
// 原有调用方式 - 保持不变
|
||
return $.post('/swaptrade/CreateTrade', formData);
|
||
// 通过YARP自动转发到 /api/SwapTrade
|
||
}
|
||
|
||
function querySwapTrades(clientId, status) {
|
||
// 原有调用方式 - 保持不变
|
||
return $.get(`/swaptrade/QueryTrades?clientId=${clientId}&status=${status || ''}`);
|
||
// 通过YARP自动转发到 /api/SwapTrade/client/{clientId}?status={status}
|
||
}
|
||
|
||
function getSwapTradeDetail(tradeId) {
|
||
// 原有调用方式 - 保持不变
|
||
return $.get(`/swaptrade/GetTradeDetail?id=${tradeId}`);
|
||
// 通过YARP自动转发到 /api/SwapTrade/{id}
|
||
}
|
||
|
||
function querySwapPositions(clientId) {
|
||
// 原有调用方式 - 保持不变
|
||
return $.get(`/swaptrade2/GetPosition?clientId=${clientId}`);
|
||
// 通过YARP自动转发到 /api/SwapPosition/client/{clientId}
|
||
}
|
||
|
||
function calculatePositionRisk(positionIds) {
|
||
// 原有调用方式 - 保持不变
|
||
return $.post('/swapposition/CalculateRisk', { positionIds: positionIds });
|
||
// 通过YARP自动转发到 /api/SwapPosition/risk/calculate
|
||
}
|
||
```
|
||
|
||
#### 路由映射规则
|
||
```csharp
|
||
// YARP路由转换规则
|
||
/*
|
||
原始路径 转发路径
|
||
/swaptrade/CreateTrade → /api/SwapTrade
|
||
/swaptrade/QueryTrades → /api/SwapTrade/client/{clientId}
|
||
/swaptrade/GetTradeDetail → /api/SwapTrade/{id}
|
||
/swaptrade2/GetPosition → /api/SwapPosition/client/{clientId}
|
||
/swapposition/CalculateRisk → /api/SwapPosition/risk/calculate
|
||
*/
|
||
```
|
||
|
||
## 四、关键技术决策说明
|
||
|
||
### 4.1 为什么使用YARP而不是Nginx/Ocelot？

### 4.2 为什么MapRouteBeforeAuth很重要？
|
||
|
||
```csharp
|
||
// 关键配置：认证前置路由
|
||
proxyPipeline.UseWhen(context =>
|
||
context.Request.Path.StartsWithSegments("/api/swap"),
|
||
handler =>
|
||
{
|
||
// 在转发前进行认证检查
|
||
handler.UseMiddleware<AuthenticationMiddleware>();
|
||
// 确保安全性
|
||
handler.UseAuthorization();
|
||
});
|
||
```
|
||
|
||
**重要性：**
|
||
✅ **安全保障** - 确保API调用经过身份验证
|
||
✅ **权限控制** - 统一的权限检查机制
|
||
✅ **审计追踪** - 完整的请求日志记录
|
||
✅ **性能优化** - 避免不必要的后端调用
|
||
|
||
### 4.3 新架构表结构详解
|
||
|
||
**核心表关系说明：**
|
||
```
|
||
trade表 (主交易表)
|
||
├── TradeType = "收益互换" (标识互换交易)
|
||
├── id (主键，关联其他表)
|
||
└── 基础交易信息字段
|
||
|
||
swap_flow表 (互换流水明细表)
|
||
├── TradeId → trade.id (外键关联)
|
||

|
||
├── UnderlyingCode (标的代码)
|
||
├── TradingQty (成交数量)
|
||
├── TradingAmount (成交金额)

|
||
|

├── ValueDate (归档日期)
|
||
└── 完整的持仓估值信息
|
||
```
|
||
|
||
### 4.4 为什么保持共享数据库？
|
||
|
||
**风险评估：**
|
||
❌ **数据库拆分风险**：
|
||
- 数据一致性难以保证
|
||
- 分布式事务复杂度高
|
||
- 迁移过程容易出错
|
||
- 维护成本显著增加
|
||
|
||
✅ **共享数据库优势**：
|
||
- 零数据迁移风险
|
||
- 保持现有业务逻辑不变
|
||
- 简化开发和测试流程
|
||
- 降低运维复杂度
|
||
|
||

|
||
## 八、监控与运维
|
||
|
||
### 6.1 关键监控指标
|
||
```yaml
|
||
# Prometheus监控配置
|
||
metrics:
|
||
- name: swap_api_response_time
|
||
help: "互换API响应时间"
|
||
type: histogram
|
||
|
||
- name: swap_api_error_rate
|
||
help: "互换API错误率"
|
||
type: gauge
|
||
|
||
- name: yarp_proxy_requests_total
|
||
help: "YARP代理请求数"
|
||
type: counter
|
||
```
|
||
|
||
### 6.2 健康检查配置
|
||
```csharp
|
||
// 互换服务健康检查
|
||
builder.Services.AddHealthChecks()
|
||
.AddSqlServer(connectionString, name: "database")
|
||
.AddRedis(redisConnectionString, name: "cache");
|
||
|
||
app.MapHealthChecks("/health", new HealthCheckOptions
|
||
{
|
||
Predicate = _ => true,
|
||
ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse
|
||
});
|
||
```
|
||
|
||
## 九、风险控制与回滚
|
||
|
||
### 7.1 风险缓解措施
|
||
✅ **渐进式切换** - 新旧服务并行运行
|
||
✅ **完整监控** - 实时性能和错误监控
|
||
✅ **自动回滚** - 配置驱动的快速回滚机制
|
||
✅ **数据备份** - 完整的数据备份策略
|
||
|
||
### 7.2 回滚方案
|
||
```bash
|
||
#!/bin/bash
|
||
# 一键回滚脚本
|
||
kubectl rollout undo deployment/yl-main-app
|
||
kubectl rollout undo deployment/yl-swap-service
|
||
```
|
||
|
||
## 十、总结
|
||
|
||
本方案通过以下关键设计确保互换模块独立化的同时保持前端无感知：
|
||
|
||
✅ **彻底现代化** - 完全基于新架构，舍弃所有老互换表结构
|
||
✅ **零业务中断** - 前端用户无感知，操作习惯完全不变
|
||
✅ **技术先进性** - 采用微软官方推荐的YARP反向代理技术
|
||
✅ **风险可控性** - 渐进式实施，完善的监控和回滚机制
|
||
✅ **扩展性强** - 为未来微服务化奠定坚实基础
|
||
|
||
通过本次独立化改造，互换模块将在保持业务连续性的前提下，实现技术架构的现代化升级，为系统的长期发展提供强有力的技术支撑。
|
||
|
||
**特别说明：**
|
||
- **swap_flow表**作为互换流水明细的核心表，维护着每笔交易的详细流水信息，包括成交数量、金额、费用等关键数据
|
||
- 与**swap_position表**密切配合，实现完整的持仓管理和流水追踪
|
||
- 是连接前端交易录入和后端风险计算的重要数据桥梁
|
||
- **trade表**作为通用交易表，统一管理包括收益互换在内的所有交易类型 |
