## 业务流程分析
### 完整业务流程
```
用户进入小程序
AI客服对话默认
连续3次AI对话后询问是否转人工
用户触发转人工
AI自动生成工单信息预填表单
用户创建工单
【核心变更】创建IM聊天室取代微信客服
同步AI对话记录到聊天室
客服人员加入聊天室
客服与客户IM对话
【可选】发起Jitsi Meet视频会议
工单处理和状态更新
工单完成/撤销,生成总结和词云
```
### 关键改动点
**取消微信客服 → 使用自建IM + Jitsi Meet**
- IM聊天室文字、图片、文件、语音消息
- 视频会议通过iframe嵌入Jitsi Meet最简实现
- 权限控制:只有聊天室成员才能创建/加入会议
---
## 数据表结构设计
### 核心表结构6+1张表
#### 1. **tb_chat_room** - 聊天室表 ⭐核心表
**用途**:一个工单对应一个聊天室
```sql

workcase_id -- 关联工单ID唯一
room_name -- 聊天室名称
status -- 状态active-活跃 closed-已关闭 archived-已归档
guest_id -- 来客ID
guest_name -- 来客姓名
ai_session_id -- AI对话会话ID从ai.tb_chat同步
current_agent_id -- 当前负责客服ID
agent_count -- 已加入客服人数
message_count -- 消息总数
unread_count -- 未读消息数(客服端)
last_message_time -- 最后消息时间
last_message -- 最后消息内容(列表展示用)
```
**业务规则**
- 创建工单时自动创建聊天室
- 聊天室状态随工单状态变化
- 工单完成后聊天室归档
---

ai_message_id -- AI原始消息ID追溯用
status -- 状态sending sent delivered read failed recalled
read_count -- 已读人数
send_time -- 发送时间
```
**业务规则**
- 从ai.tb_chat同步AI对话时设置 `is_ai_message=true`
- 会议通知作为系统消息 `message_type=meeting`
- 支持引用回复和消息撤回

## 前端集成方案
### 最简iframe嵌入实现
#### Vue 3 组件示例
```vue
<template>
<div class="video-meeting-container">
<!-- 会议控制按钮 -->
<div v-if="!meetingStarted" class="meeting-controls">
<Button @click="createMeeting" variant="gradient-blue">
<Video class="w-4 h-4 mr-2" />
发起视频会议
</Button>
</div>
<!-- Jitsi Meet iframe -->
<div v-if="meetingStarted" class="meeting-iframe-wrapper">
<iframe
:src="iframeUrl"
allow="camera; microphone; fullscreen; display-capture"
allowfullscreen
class="meeting-iframe"
></iframe>
<Button @click="endMeeting" variant="danger" class="end-meeting-btn">
结束会议
</Button>
</div>
</div>
</template>
<script setup lang="ts">
import { ref } from 'vue';
import { Video } from 'lucide-vue-next';
import { Button } from '@/components/ui';
import { createVideoMeeting, endVideoMeeting } from '@/api/workcase';
const props = defineProps<{
roomId: string;
workcaseId: string;
}>();
const meetingStarted = ref(false);
const iframeUrl = ref('');
const meetingId = ref('');
// 创建会议
const createMeeting = async () => {
try {
const res = await createVideoMeeting({
roomId: props.roomId,
workcaseId: props.workcaseId,
meetingName: `工单 ${props.workcaseId} 技术支持`,
maxParticipants: 10
});
if (res.code === 0) {
meetingId.value = res.data.meetingId;
iframeUrl.value = res.data.iframeUrl;
meetingStarted.value = true;
}
} catch (error) {
console.error('创建会议失败:', error);
}
};
// 结束会议
const endMeeting = async () => {
try {
await endVideoMeeting(meetingId.value);
meetingStarted.value = false;
iframeUrl.value = '';
} catch (error) {
console.error('结束会议失败:', error);
}
};
</script>
<style scoped lang="scss">

```
---
### API请求封装
```typescript
// src/api/workcase/meeting.ts
import { http } from '@/utils/http';
export interface CreateMeetingParams {
roomId: string;
workcaseId: string;
meetingName: string;
maxParticipants?: number;
}
export interface VideoMeetingVO {
meetingId: string;
meetingName: string;
jitsiRoomName: string;
iframeUrl: string;
status: string;
participantCount: number;
maxParticipants: number;
}
// 创建视频会议
export const createVideoMeeting = (params: CreateMeetingParams) => {
return http.post<VideoMeetingVO>('/api/workcase/meeting/create', params);
};
// 获取会议信息
export const getMeetingInfo = (meetingId: string) => {
return http.get<VideoMeetingVO>(`/api/workcase/meeting/info/${meetingId}`);
};
// 结束会议
export const endVideoMeeting = (meetingId: string) => {
return http.post(`/api/workcase/meeting/end/${meetingId}`);
};
```
---
### 移动端适配
```vue
<template>
<div class="mobile-meeting" v-if="isMobile">
<!-- 移动端全屏展示 -->
<div class="mobile-iframe-container">
<iframe
:src="iframeUrl"
allow="camera; microphone; fullscreen"
allowfullscreen
class="mobile-iframe"
></iframe>
</div>
</div>
</template>
<style scoped lang="scss">
.mobile-meeting {
position: fixed;
top: 0;
left: 0;
right: 0;
bottom: 0;
z-index: 9999;
background: #000;
}
.mobile-iframe {
width: 100vw;
height: 100vh;
border: none;
}
</style>
```
---
## 安全方案
### 1. **会议权限控制**
#### 后端验证逻辑
```java
public boolean validateMeetingAccess(String meetingId, String userId) {
// 1. 获取会议信息
VideoMeetingDO meeting = meetingMapper.selectById(meetingId);
if (meeting == null) {
throw new BusinessException("会议不存在");
}
// 2. 检查用户是否是聊天室成员
ChatRoomMemberDO member = memberMapper.selectByRoomAndUser(
meeting.getRoomId(), userId
);
if (member == null || !"active".equals(member.getStatus())) {
throw new BusinessException("您不是聊天室成员,无法加入会议");
}
return true;
}
```
---
### 2. **JWT Token生成**
```java
public String generateJwtToken(String roomName, String userId, String userName, boolean isModerator) {
long now = System.currentTimeMillis();
long exp = now + (2 * 60 * 60 * 1000); // 2小时有效期
return Jwts.builder()
.setIssuer("urbanLifeline")
.setSubject(roomName)
.setAudience("jitsi")
.claim("context", Map.of(
"user", Map.of(
"id", userId,
"name", userName,
"moderator", isModerator
)
))
.claim("room", roomName)
.setIssuedAt(new Date(now))
.setExpiration(new Date(exp))
.signWith(SignatureAlgorithm.HS256, jitsiSecretKey)
.compact();
}
```
---
### 3. **iframe URL构建**
```java
public String buildIframeUrl(String roomName, String jwtToken, JitsiConfig config) {
StringBuilder url = new StringBuilder();
url.append(jitsiServerUrl).append("/").append(roomName);
// JWT认证
url.append("?jwt=").append(jwtToken);
// Jitsi配置项
url.append("&config.startWithAudioMuted=").append(config.isStartWithAudioMuted());
url.append("&config.startWithVideoMuted=").append(config.isStartWithVideoMuted());
url.append("&config.enableWelcomePage=false");
url.append("&config.prejoinPageEnabled=false");
url.append("&config.disableDeepLinking=true");
// 界面配置
url.append("&interfaceConfig.SHOW_JITSI_WATERMARK=false");
url.append("&interfaceConfig.SHOW_WATERMARK_FOR_GUESTS=false");
url.append("&interfaceConfig.DISABLE_JOIN_LEAVE_NOTIFICATIONS=true");
return url.toString();
}
```
---
### 4. **防止未授权访问**
```java
@PostMapping("/create")
@PreAuthorize("hasAuthority('workcase:meeting:create')")
public ResultDomain<VideoMeetingVO> createMeeting(
@RequestBody @Valid CreateMeetingDTO dto,
@RequestHeader("Authorization") String token
) {
// 1. 从token解析用户信息
String userId = JwtUtil.getUserIdFromToken(token);
// 2. 验证是否是聊天室成员
if (!chatMemberService.isMemberOfRoom(dto.getRoomId(), userId)) {
return ResultDomain.failure("您不是聊天室成员,无法创建会议");
}
// 3. 创建会议
VideoMeetingVO meeting = videoMeetingService.createMeeting(dto, userId);
return ResultDomain.success(meeting);
}
```
---
## 技术要点总结
### ✅ 优势
1. **最简实现**iframe嵌入无需深度集成Jitsi服务端
2. **权限安全**JWT Token + 聊天室成员校验
3. **无状态**Jitsi Meet本身无状态只记录必要的会议元数据
4. **可扩展**可后续升级为自建Jitsi服务器
5. **成本低**使用官方meet.jit.si服务器免费
### ⚠️ 注意事项
1. **会议记录**:使用官方服务器无法录制,需自建服务器
2. **并发限制**:官方服务器有并发限制,建议后续自建
3. **网络要求**:需要良好的网络环境,可能需要科学上网
4. **数据隐私**敏感场景建议自建Jitsi服务器
---
## 下一步工作
1. ✅ 数据表已创建createTableWorkcase.sql
2. ⏳ 实现Service层业务逻辑
3. ⏳ 实现Controller层API接口
4. ⏳ 实现前端IM聊天室组件
5. ⏳ 实现前端视频会议组件
6. ⏳ 测试和调优
---
## 附录Jitsi Meet配置参考
### 推荐配置项
```javascript
const jitsiConfig = {
// 音视频设置
startWithAudioMuted: false,
startWithVideoMuted: false,
// 功能开关
enableWelcomePage: false,
prejoinPageEnabled: false,
disableDeepLinking: true,
// 录制和直播
recordingEnabled: false,
liveStreamingEnabled: false,
// 聊天和屏幕共享
enableChat: true,
enableScreenSharing: true,
// 界面定制
hideConferenceSubject: false,
hideConferenceTimer: false,
// 安全设置
enableE2EE: false, // 端到端加密
requireDisplayName: true
};
```

# 聊天室广播内存优化方案
## 🎯 优化目标
解决大量聊天室导致的内存爆炸问题。
---
## 📊 问题分析
### 当前方案的内存瓶颈
```java
// 问题1: 每个WebSocket连接占用内存
SimpMessagingTemplate 维护所有连接的Session
// 问题2: 订阅关系在内存中
/topic/chat-room/ROOM001 [User1, User2, User3, ...]
/topic/chat-room/ROOM002 [User4, User5, User6, ...]
// ... 1000个聊天室 × 平均10个用户 = 10000个订阅关系
// 问题3: 消息堆积在内存中
消息缓冲区 等待推送 内存占用
// 问题4: Session状态在内存中
每个WebSocket Session 用户信息订阅列表心跳状态
```
**内存占用估算**
- 单个WebSocket连接~50KB
- 单个订阅关系:~5KB
- 1000并发用户每人5个聊天室(50KB + 5KB×5) × 1000 = **75MB**
- 10000并发用户**750MB**(还不包括消息缓冲)
---
## 🏗️ 优化架构
### 方案一Redis Pub/Sub推荐最简单
```
┌─────────────┐ ┌──────────────────┐
│ 前端用户A │──WebSocket STOMP──►│ Spring Boot │
└─────────────┘ │ WebSocket Server │
└──────────────────┘
┌─────────────┐ │
│ 前端用户B │──WebSocket STOMP──► │ 发布消息
└─────────────┘ ↓
┌──────────────────┐
┌─────────────┐ │ Redis Pub/Sub │
│ 前端用户C │──WebSocket STOMP──►│ │
└─────────────┘ │ Channel: │
│ chat:room:ROOM001│
└──────────────────┘
│ 订阅
所有订阅此Channel的服务器节点收到消息
通过WebSocket推送给各自的在线用户
```
**核心思想**
1.**不在内存中维护订阅关系**
2.**消息不堆积,即收即转**
3.**使用Redis存储在线用户**
4.**支持水平扩展**
---
## 💻 代码实现
### 1. 添加Redis依赖
```xml
<!-- pom.xml -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
```
### 2. Redis Pub/Sub监听器
```java
package org.xyzh.workcase.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.listener.PatternTopic;
import org.springframework.data.redis.listener.RedisMessageListenerContainer;
import org.springframework.data.redis.listener.adapter.MessageListenerAdapter;
import org.xyzh.workcase.listener.ChatMessageRedisListener;
/**
* Redis消息监听配置
*/
@Configuration
public class RedisListenerConfig {
@Bean
RedisMessageListenerContainer container(
RedisConnectionFactory connectionFactory,
MessageListenerAdapter listenerAdapter
) {
RedisMessageListenerContainer container = new RedisMessageListenerContainer();
container.setConnectionFactory(connectionFactory);
// 订阅所有聊天室频道(使用通配符)
container.addMessageListener(
listenerAdapter,
new PatternTopic("chat:room:*")
);
return container;
}
@Bean
MessageListenerAdapter listenerAdapter(ChatMessageRedisListener listener) {
return new MessageListenerAdapter(listener, "handleMessage");
}
}
```
### 3. Redis消息监听器
```java
package org.xyzh.workcase.listener;
import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;

String roomId = chatMessage.getRoomId();
log.info("收到Redis消息聊天室: {}, 内容: {}", roomId, chatMessage.getContent());
// 检查当前节点是否有该聊天室的在线用户
String onlineUsersKey = "chat:room:online:" + roomId;

} else {
log.debug("聊天室 {} 在当前节点无在线用户,跳过推送", roomId);
}
} catch (Exception e) {
log.error("处理Redis消息失败", e);

}
}
```
### 5. WebSocket连接事件监听器
```java
package org.xyzh.workcase.listener;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.event.EventListener;
import org.springframework.data.redis.core.StringRedisTemplate;

---
## 🔧 进一步优化
### 1. 懒加载订阅(按需连接)
```typescript
// 前端只在进入聊天室时才建立WebSocket连接
const enterChatRoom = (roomId: string) => {
if (!wsClient.value) {
await connect(); // 懒加载连接
}
subscribeChatRoom(roomId);
};
// 离开聊天室时断开连接
const leaveChatRoom = (roomId: string) => {
unsubscribeChatRoom(roomId);
// 如果没有其他订阅断开WebSocket
if (subscriptions.size === 0) {
disconnect();
}
};
```
### 2. 连接池和限流
```java
@Configuration
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
@Override
public void configureWebSocketTransport(WebSocketTransportRegistration registration) {
// 设置消息缓冲区大小(防止堆积)
registration.setMessageSizeLimit(64 * 1024); // 64KB
registration.setSendBufferSizeLimit(512 * 1024); // 512KB
// 设置发送超时
registration.setSendTimeLimit(10 * 1000); // 10秒
// 设置最大连接数(保护服务器)
registration.setTimeToFirstMessage(30 * 1000); // 30秒内必须发送消息
}
}
```
### 3. Redis数据过期策略
```java
// 在线用户列表24小时过期
redisTemplate.expire("chat:room:online:" + roomId, 24, TimeUnit.HOURS);
// Session映射24小时过期
redisTemplate.expire("chat:session:" + sessionId, 24, TimeUnit.HOURS);
// 消息缓存如果需要1小时过期
redisTemplate.expire("chat:message:" + messageId, 1, TimeUnit.HOURS);
```
### 4. 分片策略(超大规模)
```java
// 如果有10万+并发按roomId哈希分片
String shardKey = "chat:shard:" + (roomId.hashCode() % 10);
redisTemplate.convertAndSend(shardKey, message);
// 每个服务器节点只订阅部分shard
container.addMessageListener(listenerAdapter, new PatternTopic("chat:shard:" + nodeId));
```
---
## 🎯 总结
### 优化关键点
1.**消息不在内存中堆积** - 即收即转
2.**订阅关系存储在Redis** - 内存占用降低80%+
3.**无状态转发** - 支持水平扩展
4.**自动清理断线用户** - 防止内存泄漏
5.**懒加载连接** - 按需建立WebSocket
### 适用场景
-**1000+并发用户**
-**100+聊天室**
-**需要水平扩展**
-**需要跨数据中心部署**
### 下一步
1. 添加Redis依赖
2. 实现RedisListener
3. 修改ChatMessageController
4. 添加WebSocketEventListener
5. 性能测试和调优
