# Campus Graph Demo

这是一个专门用于学习 Graph 思想的最小 Spring Boot Demo。

它刻意避免退化成线性 workflow，而是显式展示：
- State
- Node
- Edge
- Conditional Routing
- Parallel Branch
- Merge / Join
- Loop / Retry
- Terminal Node

## 图结构

```text
StartNode
  -> RouteNode

RouteNode
  -> DIRECT -> DirectAnswerNode -> EndNode
  -> COMPLEX -> KeywordRetrieveNode
  -> COMPLEX -> VectorRetrieveNode

KeywordRetrieveNode -> MergeContextNode
VectorRetrieveNode -> MergeContextNode

MergeContextNode -> JudgeNode

JudgeNode
  -> ENOUGH -> AnswerNode -> EndNode
  -> RETRY -> RewriteQueryNode
  -> FALLBACK -> FallbackNode -> EndNode

RewriteQueryNode
  -> KeywordRetrieveNode
  -> VectorRetrieveNode
```

## 运行

```powershell
.\mvnw.cmd spring-boot:run
```

## 测试

```powershell
.\mvnw.cmd test
```
