# Dify指定知识库实现方案
## 🎯 问题分析
**需求**：在调用Dify对话API时，动态指定使用哪些知识库（Dataset）
**场景**：不同部门用户使用同一个智能体，但只能访问各自授权的知识库
---
## 📋 Dify官方支持的方式
### 方式1：知识库检索API + LLM组合（推荐⭐⭐）
**优点**：
- ✅ 完全控制知识库选择
- ✅ 可以实现复杂的权限逻辑
- ✅ 灵活性最高
**缺点**：
- ⚠️ 需要自己组合API调用
- ⚠️ 无法使用Dify的完整对话管理功能
#### 步骤1：检索相关知识
```http
POST https://api.dify.ai/v1/datasets/{dataset_id}/retrieve
Authorization: Bearer {api_key}
Content-Type: application/json
{
"query": "如何申请奖学金？",
"top_k": 3,
"score_threshold": 0.7
}
```
**响应示例：**
```json
{
"records": [
{
"content": "申请奖学金需要满足以下条件...",
"score": 0.95,
"metadata": {
"document_id": "doc-123",
"document_name": "奖学金管理办法.pdf"
}
}
]
}
```
#### 步骤2：多知识库并行检索
```java
@Service
public class DifyKnowledgeService {
/**
* 从多个知识库检索相关内容
*/
public List<RetrievalRecord> retrieveFromMultipleDatasets(
String query,
List<String> datasetIds,
int topK) {
List<CompletableFuture<List<RetrievalRecord>>> futures = datasetIds.stream()
.map(datasetId -> CompletableFuture.supplyAsync(() ->
retrieveFromDataset(datasetId, query, topK)
))
.collect(Collectors.toList());
// 等待所有检索完成
CompletableFuture.allOf(futures.toArray(new CompletableFuture[0])).join();
// 合并结果并按分数排序
return futures.stream()
.map(CompletableFuture::join)
.flatMap(List::stream)
.sorted((a, b) -> Double.compare(b.getScore(), a.getScore()))
.limit(topK)
.collect(Collectors.toList());
}
/**
* 从单个知识库检索
*/
private List<RetrievalRecord> retrieveFromDataset(
String datasetId,
String query,
int topK) {
String url = difyConfig.getFullApiUrl("/datasets/" + datasetId + "/retrieve");
Map<String, Object> requestBody = new HashMap<>();
requestBody.put("query", query);
requestBody.put("top_k", topK);
requestBody.put("score_threshold", 0.7);
// HTTP请求
HttpResponse response = httpClient.post(url)
.header("Authorization", "Bearer " + apiKey)
.body(requestBody)
.execute();
return parseRetrievalResponse(response);
}
}
```
#### 步骤3：组合上下文调用LLM
```java
/**
* 使用检索到的知识回答问题
*/
public String chatWithRetrievedKnowledge(
String query,
List<RetrievalRecord> records,
String conversationId) {
// 构建上下文
String context = records.stream()
.map(r -> "【" + r.getMetadata().get("document_name") + "】\n" + r.getContent())
.collect(Collectors.joining("\n\n"));
// 构建Prompt
String prompt = String.format(
"请基于以下知识库内容回答用户问题。如果知识库中没有相关信息，请明确告知用户。\n\n" +
"知识库内容：\n%s\n\n" +
"用户问题：%s\n\n" +
"回答：",
context, query
);
// 调用Dify Completion API或直接调用LLM
return callLLM(prompt, conversationId);
}
```
---
### 方式2：Dify Workflow（工作流）⭐
**原理**：创建工作流，使用变量控制知识库选择
#### Dify工作流配置
```yaml
workflow_nodes:
- id: start
type: start
outputs:
- query # 用户问题
- dataset_ids # 知识库ID列表（变量）
- id: kb_retrieval
type: knowledge-retrieval
inputs:
query: "{{#start.query#}}"
datasets: "{{#start.dataset_ids#}}" # 从输入变量读取
top_k: 3
outputs:
- result
- id: llm
type: llm
inputs:
prompt: |
基于以下知识库内容回答问题：
{{#kb_retrieval.result#}}
用户问题：{{#start.query#}}
outputs:
- answer
- id: end
type: end
outputs:
- answer: "{{#llm.answer#}}"
```
#### API调用示例
```java
/**
* 调用Dify Workflow
*/
public void chatWithWorkflow(
String query,
List<String> datasetIds,
String userId,
SseEmitter emitter) {
String url = difyConfig.getFullApiUrl("/workflows/run");
Map<String, Object> inputs = new HashMap<>();
inputs.put("query", query);
inputs.put("dataset_ids", datasetIds); // ⭐ 动态传入知识库列表
Map<String, Object> requestBody = new HashMap<>();
requestBody.put("inputs", inputs);
requestBody.put("response_mode", "streaming");
requestBody.put("user", userId);
// 流式请求
httpClient.postStream(url, requestBody, new StreamCallback() {
@Override
public void onChunk(String chunk) {
emitter.send(chunk);
}
});
}
```
**HTTP请求示例：**
```http
POST /v1/workflows/run
Authorization: Bearer {api_key}
Content-Type: application/json
{
"inputs": {
"query": "如何申请奖学金？",
"dataset_ids": ["dataset-edu-001", "dataset-public-001"]
},
"response_mode": "streaming",
"user": "user-123"
}
```
---
### 方式3：多应用切换（不推荐）
为不同部门创建不同的Dify应用：
```
部门A -> App A（绑定知识库A1, A2）
部门B -> App B（绑定知识库B1, B2）
```
**缺点**：
- ❌ 管理复杂
- ❌ 无法共享公共知识库
- ❌ 扩展性差
---
## 🎨 推荐实现方案
### 方案：知识库检索API + 自定义LLM调用
#### 完整实现代码
```java

List<UserDeptRoleVO> userDeptRoles = LoginUtil.getCurrentDeptRole();
// 2. 查询用户有权限的知识库（自动权限过滤✅）
TbAiKnowledge filter = new TbAiKnowledge();
filter.setStatus(1); // 只查询启用的
List<TbAiKnowledge> authorizedKnowledges =
knowledgeMapper.selectAiKnowledges(
filter,
userDeptRoles // 直接传入LoginUtil获取的用户权限信息
);
// 3. 提取Dify Dataset IDs
List<String> datasetIds = authorizedKnowledges.stream()

## 📊 三种方式对比
| 方案 | 灵活性 | 实现难度 | 性能 | 推荐度 |
|------|--------|----------|------|--------|
| 检索API + 自定义LLM | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
| Workflow工作流 | ⭐⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ |
| 多应用切换 | ⭐⭐ | ⭐ | ⭐⭐⭐ | ⭐ |
---
## 🎯 最终推荐方案
**使用"检索API + 自定义LLM"方案**
**理由**：
1. ✅ 完全控制知识库访问权限
2. ✅ 可以实现复杂的部门隔离逻辑
3. ✅ 支持并行检索多个知识库
4. ✅ 可以自定义Prompt和上下文
5. ✅ 灵活性最高，适合企业级应用
**实现步骤**：
1. 用户发起对话
2. 根据用户权限查询可访问的知识库（Mapper已实现✅）
3. 并行调用Dify检索API获取相关内容
4. 合并结果构建上下文
5. 调用LLM流式生成答案
6. 保存对话记录（含知识来源）
这样既利用了Dify的知识库能力，又保持了完全的控制权！🎉

## 💡 使用示例
### 1. 创建智能体并进行流式对话
```typescript
import { aiAgentConfigApi, chatApi } from '@/apis/ai';
// 1. 创建智能体
const agentResult = await aiAgentConfigApi.createAgent({
name: '智能助手',
description: '帮助用户解答问题',
systemPrompt: '你是一个智能助手...',
modelName: 'gpt-3.5-turbo',
status: 1
});
const agentId = agentResult.data?.ID;
// 2. 流式对话
await chatApi.streamChat(
{
agentId: agentId!,
query: '你好，请介绍一下你自己',
stream: true
},
{
onMessage: (chunk) => {
console.log('接收到消息片段：', chunk);
},
onMessageEnd: (metadata) => {
console.log('消息结束，元数据：', metadata);
},
onComplete: () => {
console.log('对话完成');
},
onError: (error) => {
console.error('对话出错：', error);
}
}
);
```
### 2. 创建知识库并上传文件
```typescript
import { knowledgeApi, fileUploadApi } from '@/apis/ai';
// 1. 创建知识库
const knowledgeResult = await knowledgeApi.createKnowledge({
name: '产品文档知识库',
description: '包含所有产品相关文档',
indexingTechnique: 'high_quality',
embeddingModel: 'text-embedding-ada-002'
});
const knowledgeId = knowledgeResult.data?.ID;
// 2. 上传文件
const files = document.querySelector('input[type="file"]').files;
const uploadResult = await fileUploadApi.batchUploadFiles(
knowledgeId!,
Array.from(files)
);
console.log('上传成功：', uploadResult.data);
```
### 3. 搜索对话历史
```typescript
import { chatHistoryApi } from '@/apis/ai';
// 搜索包含关键词的会话
const searchResult = await chatHistoryApi.pageUserConversations({
keyword: '产品',
isFavorite: true,
startDate: '2024-01-01',
pageParam: {
pageNumber: 1,
pageSize: 20
}
});
console.log('搜索结果：', searchResult.dataList);
```
### 4. 导出对话记录
```typescript
import { chatHistoryApi } from '@/apis/ai';
// 导出为Markdown
const markdownResult = await chatHistoryApi.exportConversationAsMarkdown(
conversationId
);
// 创建下载链接
const blob = new Blob([markdownResult.data!], { type: 'text/markdown' });
const url = URL.createObjectURL(blob);
const a = document.createElement('a');
a.href = url;
a.download = `conversation_${conversationId}.md`;
a.click();
// 或者直接使用下载方法
chatHistoryApi.downloadExport(conversationId, 'markdown');
```

# AI模块数据同步检查报告
## ✅ 检查日期：2025-11-04
## 📊 同步状态总览
### ✅ 完全同步（3/5个Service）
#### 1. AiKnowledgeServiceImpl ✅ **已完成所有同步**
- ✅ **createKnowledge**: 先调用`difyApiClient.createDataset()`创建Dify知识库，再保存本地
- ✅ **updateKnowledge**: 检测title/description变化，调用`difyApiClient.updateDataset()`同步到Dify ✅ **已修复**
- ✅ **deleteKnowledge**: 先调用`difyApiClient.deleteDataset()`删除Dify知识库，再删除本地
---
#### 2. AiUploadFileServiceImpl ✅
- ✅ **uploadToKnowledge**: 调用`difyApiClient.uploadDocumentByFile()`上传到Dify，再保存本地
- ✅ **batchUploadToKnowledge**: 批量上传到Dify
- ✅ **deleteFile**: 先调用`difyApiClient.deleteDocument()`删除Dify文档，再删除本地
- ✅ **syncFileStatus**: 从Dify同步文件处理状态
- ✅ **syncKnowledgeFiles**: 批量同步知识库的所有文件状态
---
#### 3. AiChatServiceImpl ✅
- ✅ **streamChat**: 在对话时自动获取Dify的conversation_id并保存到`difyConversationId`字段
- ✅ **blockingChat**: 同上
- ⚠️ **createConversation**: 只创建本地会话，**Dify conversation在首次对话时自动创建**
- ⚠️ **updateConversation**: 只更新本地（title等元数据），**Dify不支持单独的conversation管理API**
- ⚠️ **deleteConversation**: 只删除本地，**Dify没有提供删除conversation的API**
**说明**：
- Dify的conversation是在对话时自动创建和管理的
- 本地的TbAiConversation表用于管理会话元数据（标题、摘要、收藏等）
- `difyConversationId`字段用于关联Dify的会话ID
- **这种设计是合理的**，不需要修改
---
### ✅ 无需同步（2/5个Service）
#### 4. AiAgentConfigServiceImpl ✅
- ✅ **createAgent**: 只创建本地配置
- ✅ **updateAgent**: 只更新本地配置
- ✅ **deleteAgent**: 只删除本地配置
**说明**：
- 智能体配置是本地管理的元数据
- `difyAppId`字段只是引用Dify的App ID，不需要通过API创建
- Dify App需要在Dify平台手动创建，然后将App ID填入配置
- **这种设计是合理的**，不需要修改
---
#### 5. AiChatHistoryServiceImpl ✅
- ✅ **所有方法都是查询、统计、导出操作**
- ✅ 不涉及数据修改，无需同步
---
## ✅ 已修复的问题
### ✅ 问题1：知识库更新未同步到Dify（已修复）
**文件**: `AiKnowledgeServiceImpl.java`
**方法**: `updateKnowledge`
**问题**: 更新知识库的title或description时，只更新了本地数据库，没有调用Dify API
**修复内容**:
1. 新增 `DifyApiClient.updateDataset()` 方法
2. 新增 `DatasetUpdateRequest` DTO类
3. 在 `updateKnowledge()` 方法中添加Dify同步逻辑：
- 检测title或description是否改变
- 如果改变，调用Dify API更新
- Dify更新失败不阻塞本地更新，只记录日志
**修复时间**: 2025-11-04
---
## ✅ 数据同步最佳实践总结
### 创建操作（CREATE）
1. 先调用Dify API创建资源
2. 保存Dify返回的ID到本地数据库
3. 如果Dify创建失败，不保存本地记录
### 更新操作（UPDATE）
1. 如果更新的字段在Dify中存在对应资源，先更新Dify
2. Dify更新成功或失败都记录日志
3. 更新本地数据库
### 删除操作（DELETE）
1. 先调用Dify API删除资源
2. 即使Dify删除失败也继续删除本地记录（逻辑删除）
3. 记录删除日志
### 同步操作（SYNC）
1. 定期从Dify同步状态（如文件向量化状态）
2. 使用异步任务避免阻塞主流程
---
## 📋 修复清单
- [x] 修复 `AiKnowledgeServiceImpl.updateKnowledge()` - 添加Dify知识库更新同步 ✅ **已完成**
---
## 📝 备注
1. **Dify Conversation管理**：Dify的conversation是在对话时自动创建的，不需要单独的创建API，当前实现合理。
2. **智能体配置**：智能体配置是本地元数据，difyAppId只是引用，需要在Dify平台手动创建App，当前实现合理。
3. **文件上传**：已完美同步，包括上传、删除、状态同步等。
4. **知识库管理**：除了更新操作，其他都已同步。
---
## 🎯 下一步行动
1. 实现 `AiKnowledgeServiceImpl.updateKnowledge()` 的Dify同步功能
2. 测试更新知识库后在Dify平台的显示效果
3. 考虑添加批量同步功能，用于修复历史数据不一致问题

# 智能体中实现部门知识库隔离方案
## 🎯 业务场景
**需求**：一个智能体（如"校园助手"），不同部门的用户访问时，只能查询到本部门及公共的知识库。
**示例**：
- 教务处用户：可访问"教务知识库" + "公共知识库"
- 财务处用户：可访问"财务知识库" + "公共知识库"
- 学生：只能访问"公共知识库"
---
## 📋 实现方案（推荐）
### 方案架构
```
用户请求
↓
1. 获取用户部门和角色
↓
2. 查询有权限的知识库列表（已实现✅）
↓
3. 在Dify对话时动态指定知识库
↓
4. 返回结果（只包含授权知识库的内容）
```
---
## 🔧 技术实现
### 1. 知识库分类（数据库层）
#### 1.1 创建知识库时设置权限
```java
@Service
public class AiKnowledgeServiceImpl {
@Transactional
public ResultDomain<TbAiKnowledge> createKnowledge(
TbAiKnowledge knowledge,
KnowledgePermissionType permissionType) {
// 1. 获取当前登录用户信息（通过LoginUtil）⭐
TbSysUser currentUser = LoginUtil.getCurrentUser();
List<UserDeptRoleVO> userDeptRoles = LoginUtil.getCurrentDeptRole();
String deptId = userDeptRoles.isEmpty() ? null : userDeptRoles.get(0).getDeptID();
// 2. 保存知识库
knowledge.setCreator(currentUser.getID());
knowledge.setCreatorDept(deptId);
knowledgeMapper.insert(knowledge);
// 3. 根据权限类型创建权限记录
switch (permissionType) {
case PUBLIC:
// 公开知识库：所有人可读
createPublicPermission(knowledge.getID());
break;
case DEPARTMENT:
// 部门知识库：本部门所有人可读写
createDepartmentPermission(knowledge.getID(), deptId);
break;
case DEPARTMENT_INHERIT:
// 部门继承：本部门及子部门可读
createDepartmentInheritPermission(knowledge.getID(), deptId);
break;
case ROLE:
// 角色知识库：特定角色可读（跨部门）
createRolePermission(knowledge.getID(), roleIds);
break;
case PRIVATE:
// 私有知识库：仅创建者所在部门的特定角色
createPrivatePermission(knowledge.getID(), deptId, roleIds);
break;
}
return ResultDomain.success(knowledge);
}
// 创建公开权限
private void createPublicPermission(String knowledgeId) {
TbResourcePermission permission = new TbResourcePermission();
permission.setID(UUID.randomUUID().toString());
permission.setResourceType(10); // AI_KNOWLEDGE
permission.setResourceId(knowledgeId);
permission.setDeptId(null); // NULL表示不限部门
permission.setRoleId(null); // NULL表示不限角色
permission.setCanRead(true);
permission.setCanWrite(false);
permission.setCanExecute(false);
resourcePermissionMapper.insert(permission);
}
// 创建部门权限
private void createDepartmentPermission(String knowledgeId, String deptId) {
TbResourcePermission permission = new TbResourcePermission();
permission.setID(UUID.randomUUID().toString());
permission.setResourceType(10);
permission.setResourceId(knowledgeId);
permission.setDeptId(deptId); // 指定部门
permission.setRoleId(null); // 部门内所有角色
permission.setCanRead(true);
permission.setCanWrite(true); // 部门成员可编辑
permission.setCanExecute(false);
resourcePermissionMapper.insert(permission);
}
// 创建部门继承权限（利用dept_path）
private void createDepartmentInheritPermission(String knowledgeId, String deptId) {
// 查询部门信息
TbSysDept dept = deptMapper.selectById(deptId);
// 为本部门创建权限（已通过dept_path自动继承给子部门）
TbResourcePermission permission = new TbResourcePermission();
permission.setID(UUID.randomUUID().toString());
permission.setResourceType(10);
permission.setResourceId(knowledgeId);
permission.setDeptId(deptId);
permission.setRoleId(null);
permission.setCanRead(true);
permission.setCanWrite(false); // 子部门只读
permission.setCanExecute(false);
resourcePermissionMapper.insert(permission);
// dept_path机制会自动让子部门继承此权限
}
}
```
#### 1.2 权限类型枚举
```java
public enum KnowledgePermissionType {
PUBLIC, // 公开（所有人可读）
DEPARTMENT, // 部门（本部门可读写）
DEPARTMENT_INHERIT, // 部门继承（本部门及子部门可读）
ROLE, // 角色（特定角色跨部门可读）
PRIVATE // 私有（特定部门+角色）
}
```
---
### 2. 对话时动态过滤知识库（Service层）
```java
@Service
public class AiChatServiceImpl {
@Autowired
private AiKnowledgeMapper knowledgeMapper;
@Autowired
private DifyApiClient difyApiClient;
/**
* 流式对话（带知识库隔离）
*/
public void streamChat(
String message,
String conversationId,
String userId,
SseEmitter emitter) {
// 1. 获取当前登录用户的部门角色信息（通过LoginUtil）⭐
List<UserDeptRoleVO> userDeptRoles = LoginUtil.getCurrentDeptRole();
// 2. 查询用户有权限的知识库列表（自动权限过滤✅）
TbAiKnowledge filter = new TbAiKnowledge();
filter.setStatus(1); // 只查询启用的知识库
List<TbAiKnowledge> availableKnowledges = knowledgeMapper.selectAiKnowledges(
filter,
userDeptRoles // 自动根据用户部门角色过滤
);
// 3. 提取Dify Dataset IDs
List<String> datasetIds = availableKnowledges.stream()
.map(TbAiKnowledge::getDifyDatasetId)
.filter(Objects::nonNull)
.collect(Collectors.toList());
// 4. 调用Dify API（指定知识库列表）
DifyChatRequest request = DifyChatRequest.builder()
.query(message)
.conversationId(conversationId)
.user(userId)
.datasets(datasetIds) // ⭐ 动态指定知识库
.stream(true)
.build();
// 5. 流式响应
difyApiClient.streamChat(request, new StreamCallback() {
@Override
public void onChunk(String chunk) {
emitter.send(chunk);
}
@Override
public void onComplete(DifyChatResponse response) {
// 保存消息记录
saveMessage(conversationId, userId, message, response);
emitter.complete();
}
@Override
public void onError(Throwable error) {
emitter.completeWithError(error);
}
});
}
}
```
---
### 3. Dify API请求参数
```java
@Data
@Builder
public class DifyChatRequest {
private String query; // 用户问题
private String conversationId; // 会话ID
private String user; // 用户ID
@JsonProperty("datasets")
private List<String> datasets; // ⭐ 指定知识库ID列表
private Boolean stream; // 是否流式
private Map<String, Object> inputs; // 额外输入
}
```
**Dify API调用示例：**
```json
POST /v1/chat-messages
{
"query": "如何申请奖学金？",
"conversation_id": "conv-123",
"user": "user-001",
"datasets": [
"dataset-edu-001", // 教务知识库
"dataset-public-001" // 公共知识库
],
"stream": true
}
```
---
### 4. 前端展示（可选）
可以在前端显示用户当前可访问的知识库：
```typescript
interface ChatPageState {
availableKnowledges: Knowledge[]; // 用户可访问的知识库
selectedKnowledges: string[]; // 用户选择的知识库（可多选）
}
// 用户可以手动选择使用哪些知识库
async function sendMessage(message: string) {
const response = await axios.post('/ai/chat', {
message,
conversationId,
knowledgeIds: selectedKnowledges // 从可用列表中选择
});
}
```
---
## 🔐 权限控制流程
### 创建知识库流程
```
1. 用户创建知识库
↓
2. 选择权限类型（公开/部门/角色/私有）
↓
3. 系统创建知识库记录
↓
4. 自动创建权限记录（tb_resource_permission）
↓
5. 同步到Dify（创建Dataset）
```
### 对话查询流程
```
1. 用户发起对话
↓
2. 获取用户部门角色（UserDeptRoleVO）
↓
3. 查询有权限的知识库（Mapper自动过滤）
↓
4. 提取Dify Dataset IDs
↓
5. 调用Dify API（指定datasets参数）
↓
6. Dify只从指定知识库中检索
↓
7. 返回结果
```

## 📊 权限矩阵示例
| 知识库 | 类型 | 教务处-管理员 | 教务处-教师 | 财务处-管理员 | 学生 |
|--------|------|---------------|-------------|---------------|------|
| 公共知识库 | PUBLIC | ✅ 读 | ✅ 读 | ✅ 读 | ✅ 读 |
| 教务知识库 | DEPARTMENT | ✅ 读写 | ✅ 读写 | ❌ | ❌ |
| 财务知识库 | DEPARTMENT | ❌ | ❌ | ✅ 读写 | ❌ |
| 教师手册 | ROLE | ✅ 读 | ✅ 读 | ❌ | ❌ |
| 管理规范 | PRIVATE | ✅ 读写执行 | ❌ | ✅ 读写执行 | ❌ |
---
## 🎨 前端交互优化
### 1. 知识库选择器
```vue
<template>
<div class="knowledge-selector">
<h3>可用知识库</h3>
<el-checkbox-group v-model="selectedKnowledges">
<el-checkbox
v-for="kb in availableKnowledges"
:key="kb.id"
:label="kb.id">
{{ kb.title }}
<el-tag size="small">{{ kb.category }}</el-tag>
</el-checkbox>
</el-checkbox-group>
</div>
</template>
```
### 2. 知识库来源标注
在AI回答中标注知识来源：
```json
{
"answer": "申请奖学金需要...",
"sources": [
{
"knowledge_id": "kb-001",
"knowledge_title": "奖学金管理办法",
"department": "教务处",
"snippet": "第三条..."
}
]
}
```
---
## ⚡ 性能优化
### 1. 缓存用户可访问的知识库
```java
// 注意：缓存key应该使用用户ID + 部门角色组合，确保权限变更后缓存失效
@Cacheable(value = "user:knowledges", key = "#root.target.getCurrentUserCacheKey()")
public List<TbAiKnowledge> getUserAvailableKnowledges() {
// 通过LoginUtil获取当前用户的部门角色信息⭐
List<UserDeptRoleVO> userDeptRoles = LoginUtil.getCurrentDeptRole();
return knowledgeMapper.selectAiKnowledges(
new TbAiKnowledge(),
userDeptRoles
);
}
// 生成缓存key（包含用户ID和部门角色信息）
private String getCurrentUserCacheKey() {
TbSysUser user = LoginUtil.getCurrentUser();
List<UserDeptRoleVO> roles = LoginUtil.getCurrentDeptRole();
String roleIds = roles.stream()
.map(r -> r.getDeptID() + ":" + r.getRoleID())
.collect(Collectors.joining(","));
return user.getID() + ":" + roleIds;
}
```
### 2. 知识库预加载
在用户登录时预加载知识库列表，缓存到Redis：
```java
// 登录时
String cacheKey = "user:" + userId + ":knowledges";
List<String> datasetIds = getDatasetIds(userId);
redisTemplate.opsForValue().set(cacheKey, datasetIds, 1, TimeUnit.HOURS);
// 对话时直接使用
List<String> datasetIds = redisTemplate.opsForValue().get(cacheKey);
```
---
## 🔄 知识库共享场景
### 场景1：跨部门协作知识库
```java
// 教务处和学工处共享的"学生管理"知识库
createKnowledge("学生管理知识库", Arrays.asList(
new Permission("dept_academic", null, true, false, false),
new Permission("dept_student", null, true, false, false)
));
```
### 场景2：角色知识库（跨部门）
```java
// 所有"教师"角色可访问（不限部门）
createKnowledge("教师手册", Arrays.asList(
new Permission(null, "teacher", true, false, false)
));
```
### 场景3：临时授权
```java
// 给特定用户临时授权
@Transactional
public void grantTemporaryAccess(String knowledgeId, String userId, Integer hours) {
// 创建临时权限记录
TbResourcePermission permission = new TbResourcePermission();
permission.setResourceId(knowledgeId);
permission.setUserId(userId); // 扩展字段：用户级权限
permission.setExpireTime(LocalDateTime.now().plusHours(hours));
permissionMapper.insert(permission);
}
```

## 🎯 总结
**核心思路**：
1. **数据库层**：通过`tb_resource_permission`控制知识库访问权限（已实现✅）
2. **应用层**：对话时根据用户权限动态查询可用知识库
3. **Dify层**：通过API的`datasets`参数限制检索范围
**优势**：
- ✅ 灵活：支持公开、部门、角色、私有等多种权限模型
- ✅ 安全：数据库层权限控制，无法绕过
- ✅ 性能：利用dept_path支持部门继承，查询高效
- ✅ 可扩展：可以轻松添加新的权限类型
**这个方案充分利用了您现有的权限系统设计！** 🎉
