## 🔄 Current Phase
|
||
|
||
### Goal
|
||
完成 AI 服务 DTO 定义、AiServiceClient 实现、熔断与降级、清理旧代码。
|
||
|
||
### Sub Tasks
|
||
- [ ] TASK-030: 定义 AI 服务 DTO ⏳ [AC-MCA-04-REQ, AC-MCA-05]
|
||
- [ ] TASK-031: 实现 AiServiceClient ⏳ [AC-MCA-04, AC-MCA-05]
|
||

|
||
- [ ] TASK-033: 删除旧 AiService ⏳
|
||
|
||
### Next Action (Must be Specific)
|
||
|
||
**Immediate**: 创建 `ChatRequest.java`、`ChatResponse.java` AI 服务 DTO。
|
||
|
||
**Details**:
|
||
1. file: `src/main/java/com/wecom/robot/dto/ai/ChatRequest.java`
|
||
2. action: 定义 ChatRequest DTO，包含 sessionId、currentMessage、channelType、history 字段
|
||
3. reference:
|
||
- `spec/ai-robot/design.md` 第 6.1 节（AI 服务调用）
|
||
- `spec/ai-robot/openapi.deps.yaml`（AI 服务契约）
|
||
4. constraints:
|
||
- 字段与 openapi.deps.yaml 一致
|
||
- 包含映射方法 (InboundMessage → ChatRequest)
|
||
- 代码/注释必须包含 [AC-MCA-04-REQ] 标注

|
||
### Key Decisions (Why / Impact)
|
||
|
||
- decision: 统一消息模型 (InboundMessage/OutboundMessage)
|
||
reason: 实现渠道无关的消息处理，Controller 层负责验签/解析，Router 层处理统一消息
|
||
impact: 后续新增渠道只需实现 ChannelAdapter，无需修改核心路由逻辑
|
||
|
||
- decision: 使用 Resilience4j 实现熔断
|
||
reason: 与 Spring Boot 2.7 兼容良好，支持断路器、限流、超时
|
||
impact: AI 服务调用具备熔断/降级能力，提升系统稳定性
|
||
|
||
- decision: 内部字段统一用 `content`，AI 服务契约用 `currentMessage`
|
||
reason: 保持内部命名一致性，映射在 AiServiceClient 层处理
|
||
impact: 避免后续 DTO 命名混乱
|
||
|
||
- decision: ChannelAdapter 接口分离为核心能力和可选能力
|
||
reason: 不同渠道支持的能力不同，接口分离允许按需实现
|
||
impact: WeChatAdapter 实现全部接口，其他渠道可按需实现
|
||
|
||
### Code Snippets (Reference)
|
||
|
||
```java
|
||
// ChannelAdapter 接口定义 (design.md 3.1)
|
||
public interface ChannelAdapter {
|
||
String getChannelType();
|
||
boolean sendMessage(OutboundMessage message);
|
||
}
|
||
|
||
// MessageRouterService 接口定义 (design.md 3.2)
|
||
public interface MessageRouterService {
|
||
void processInboundMessage(InboundMessage message);
|
||
void routeBySessionState(Session session, InboundMessage message);
|
||
void dispatchToAiService(Session session, InboundMessage message);
|
||
void dispatchToManualCs(Session session, InboundMessage message);
|
||
void dispatchToPendingPool(Session session, InboundMessage message);
|
||
}
