# 任务描述
|
||||
通过 Websocket 向前端发送各类消息，比如位置更新消息、红绿灯状态消息、预警告警消息等，这些消息由相应的事件触发，比如位置更新消息，就是收到了新的航空器、车辆或无人车的位置信息，就转发给前端。
|
||||
|
||||
# 项目概述
|
||||
碰撞避免系统，采用Java Spring Boot后端，需要设计并实现一个完整的WebSocket消息推送系统，将各类实时数据和事件通过WebSocket推送给前端。
|
||||
|
||||
# 分析 (由 RESEARCH 模式填充)
|
||||
|
||||
## 现有WebSocket基础设施分析
|
||||
|
||||
### Java Spring Boot端WebSocket配置
|
||||
- **WebSocketConfig**: 已配置STOMP端点(`/ws`)和消息代理(`/topic`)
|
||||
- **消息转换器**: 已配置Jackson JSON转换器
|
||||
- **跨域支持**: 已启用SockJS和跨域访问
|
||||
|
||||
### 现有WebSocket控制器
|
||||
1. **MessageController**: 基础消息处理(`/app/send` -> `/topic/messages`)
|
||||
2. **GeopositionController**: 位置数据查询接口
|
||||
- `/app/getGeoposition` -> `/topic/geoSition`
|
||||
- `/app/getAllVehiclePositions` -> `/topic/allVehiclePositions`
|
||||
- `/app/getVehiclesByType` -> `/topic/vehiclesByType`
|
||||
|
||||
## 测试系统WebSocket客户端分析 (消息格式参考)
|
||||
|
||||
### 连接信息
|
||||
- **连接地址**: `ws://localhost:8010` (原生WebSocket，非STOMP)
|
||||
- **消息格式**: 标准JSON格式，前端使用`JSON.parse(event.data)`解析
|
||||
|
||||
### 支持的消息类型及格式
|
||||
|
||||
#### 1. 位置更新消息 (`position_update`)
|
||||
```json
|
||||
{
|
||||
"type": "position_update",
|
||||
"object_id": "VEHICLE_001|AIRCRAFT_CA8888|SPECIAL_VEHICLE_001",
|
||||
"object_type": "UNMANNED_VEHICLE|AIRCRAFT|AIRPORT_VEHICLE",
|
||||
"position": {
|
||||
"latitude": 39.12345,
|
||||

|
||||
},
|
||||
"heading": 90.0,
|
||||
"speed": 15.5,
|
||||

|
||||
}
|
||||
```
|
||||
|
||||
#### 2. 红绿灯状态消息 (`intersection_traffic_light_status`) - 基于Java SignalState枚举
|
||||
```json
|
||||
{
|
||||
"type": "intersection_traffic_light_status",
|
||||
"intersection_id": "INTER001",
|
||||
"position": {
|
||||
"latitude": 39.12345,
|
||||
"longitude": 116.12345
|
||||
},
|
||||
"ns_status": "RED|GREEN|YELLOW",
|
||||
"ew_status": "RED|GREEN|YELLOW",
|
||||
"timestamp": 1703472000000000
|
||||
}
|
||||
```
|
||||
|
||||
#### 3. 车辆控制指令消息 (`vehicle_command`) - 基于Java CommandType和CommandReason枚举
|
||||
```json
|
||||
{
|
||||
"type": "vehicle_command",
|
||||
"vehicleId": "VEHICLE_001",
|
||||
"vehicleType": "UNMANNED_VEHICLE|AIRCRAFT|AIRPORT_VEHICLE",
|
||||
"commandType": "ALERT|WARNING|RESUME|SIGNAL|PARKING",
|
||||
"reason": "TRAFFIC_LIGHT|AIRCRAFT_CROSSING|SPECIAL_VEHICLE|AIRCRAFT_PUSH|RESUME_TRAFFIC|PARKING_SIDE",
|
||||
"targetLatitude": 39.12345, // 可选
|
||||
"targetLongitude": 116.12345, // 可选
|
||||
"signalState": "RED|GREEN|YELLOW", // 可选，SIGNAL指令用，基于SignalState枚举
|
||||
"intersectionId": "INTER001", // 可选，SIGNAL指令用
|
||||
"timestamp": 1703472000000000
|
||||
}
|
||||
```
|
||||
|
||||
#### 4. 碰撞预警消息 (`collision_warning`) - 基于Java MovingObjectType枚举
|
||||
```json
|
||||
{
|
||||
"type": "collision_warning",
|
||||
"object1_id": "VEHICLE_001",
|
||||
"object1_type": "UNMANNED_VEHICLE|AIRCRAFT|AIRPORT_VEHICLE",
|
||||
"object2_id": "AIRCRAFT_CA8888",
|
||||
"object2_type": "UNMANNED_VEHICLE|AIRCRAFT|AIRPORT_VEHICLE",
|
||||
"risk_level": "HIGH|MEDIUM|LOW",
|
||||
"distance": 50.0,
|
||||
"estimated_time": 3.5,
|
||||
"timestamp": 1703472000000000
|
||||
}
|
||||
```
|
||||
|
||||
#### 5. 心跳消息 (`heartbeat`)
|
||||
```json
|
||||
{
|
||||
"type": "heartbeat",
|
||||
"timestamp": 1703472000000000
|
||||
}
|
||||
```
|
||||
|
||||
### 前端处理特点
|
||||
1. **实时地图更新**: 位置消息实时更新地图上的标记位置和方向
|
||||
2. **航空器安全边框**: 航空器显示多层安全边框(250m预警区，150m核心区，100m紧急区)
|
||||
3. **车辆指令可视化**: 无人车图标显示指令状态(A-告警，W-预警，R-恢复)
|
||||
4. **红绿灯状态显示**: 路口南北/东西方向分别显示红绿灯状态
|
||||
5. **消息分类显示**: 不同类型消息使用不同颜色在日志中显示
|
||||
|
||||
### 关键技术要点
|
||||
- **时间戳格式**: 使用微秒级Unix时间戳(`timestamp/1000000`转换为毫秒)
|
||||
- **对象类型**: 使用Java枚举类型明确指定，不依赖ID前缀判断
|
||||
- **协议差异**: 测试系统使用原生WebSocket，Java端使用STOMP协议
|
||||
- **消息格式**: JSON格式便于Web前端处理和调试
|
||||
- **消息过滤**: 前端会忽略心跳消息，只处理业务消息
|
||||
|
||||
## 发现的问题和改进需求
|
||||
|
||||
### 1. Java端WebSocket功能不完整
|
||||
- 当前仅提供查询接口，缺乏主动推送能力
|
||||
- 缺乏事件驱动的消息分发机制
|
||||
- 需要重新实现完整的消息推送系统
|
||||
|
||||
### 2. 需要实现的消息类型 (参考C++格式)
|
||||
1. **位置更新消息**: `position_update`
|
||||
2. **红绿灯状态消息**: `traffic_light_status` / `intersection_traffic_light_status`
|
||||
3. **碰撞预警消息**: `collision_warning`
|
||||
4. **车辆指令消息**: `vehicle_command`
|
||||
5. **系统告警消息**: `system_alert` (超时、异常等)
|
||||
|
||||
### 3. 事件触发场景
|
||||
- 数据采集服务获取新数据时
|
||||
- 数据处理结果产生时
|
||||
- 系统状态变化时
|
||||
- 异常和告警发生时
|
||||

||||
# 提议的解决方案 (由 INNOVATE 模式填充)
|
||||
|
||||
## 方案：基于Spring事件机制的WebSocket消息推送系统
|
||||
|
||||
### 核心设计理念
|
||||
采用扁平化事件架构，数据处理完成后直接发布业务事件，WebSocket监听器实时推送消息，确保高性能和实时性。
|
||||
|
||||
### 系统架构设计
|
||||
|
||||
#### 1. 简化的事件流程
|
||||
```
|
||||
数据采集 → 数据处理 → 发布业务事件 → WebSocket实时推送 → 前端
|
||||
↓
|
||||
Redis缓存 (用于重连恢复)
|
||||
```
|
||||
|
||||
#### 2. 事件类型定义 (扁平化分类)
|
||||
|
||||
**基础事件接口**
|
||||
```java
|
||||
public interface WebSocketEvent {
|
||||
String getEventId();
|
||||
long getTimestamp();
|
||||
String getEventType();
|
||||
Object getPayload();
|
||||
}
|
||||
```
|
||||
|
||||
**业务事件分类 (基于Java项目现有枚举)**
|
||||
- `PositionUpdateEvent`: 位置更新 (基于MovingObjectType: AIRCRAFT, AIRPORT_VEHICLE, UNMANNED_VEHICLE)
|
||||
- `TrafficLightStatusEvent`: 红绿灯状态变化 (基于SignalState: RED, GREEN, YELLOW)
|
||||
- `CollisionWarningEvent`: 碰撞预警
|
||||
- `VehicleCommandEvent`: 车辆指令 (基于CommandType: ALERT, SIGNAL, WARNING, RESUME, PARKING)
|
||||
- `SystemAlertEvent`: 系统告警
|
||||
|
||||
#### 3. 消息封装标准化
|
||||
|
||||
**统一消息格式 (符合前端JSON格式要求)**
|
||||
```java
|
||||
public class WebSocketMessage<T> {
|
||||
private String type; // 消息类型 (position_update, vehicle_command等)
|
||||
private Long timestamp; // 微秒级时间戳
|
||||
private String messageId; // 消息唯一ID (可选)
|
||||
private T payload; // 消息载荷 (JSON格式的具体数据)
|
||||
|
||||
// 对于位置更新消息，payload包含:
|
||||
// object_id, object_type (MovingObjectType), position, heading, speed
|
||||
|
||||
// 对于车辆指令消息，payload包含:
|
||||
// vehicleId, vehicleType (MovingObjectType), commandType (CommandType),
|
||||
// reason (CommandReason), signalState (SignalState)等
|
||||
}
|
||||
```
|
||||
|
||||
**消息优先级**
|
||||
```java
|
||||
public enum MessagePriority {
|
||||
URGENT, // 紧急 (安全告警)
|
||||
HIGH, // 高优先级 (碰撞预警)
|
||||
NORMAL, // 普通 (位置更新)
|
||||
LOW // 低优先级 (系统状态)
|
||||
}
|
||||
```
|
||||
|
||||
#### 4. 事件发布机制 (仅在数据处理服务中)
|
||||
|
||||
**数据处理服务发布事件**
|
||||
```java
|
||||
@Service
|
||||
public class DataProcessingService {
|
||||
private final ApplicationEventPublisher eventPublisher;
|
||||
|
||||
// 处理位置数据后发布事件
|
||||
public void processVehiclePositions(List<VehicleLocation> locations) {
|
||||
// 数据处理逻辑...
|
||||
|
||||
// 处理完成后发布事件
|
||||
for (VehicleLocation location : locations) {
|
||||
eventPublisher.publishEvent(new PositionUpdateEvent(location));
|
||||
}
|
||||
}
|
||||
|
||||
// 碰撞检测后发布预警事件
|
||||
public void detectCollisions() {
|
||||
// 碰撞检测逻辑...
|
||||
|
||||
if (riskDetected) {
|
||||
eventPublisher.publishEvent(new CollisionWarningEvent(risk));
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**WebSocket消息监听器 (实时推送)**
|
||||
```java
|
||||
@Component
|
||||
public class WebSocketMessageBroadcaster {
|
||||
|
||||
private final SimpMessagingTemplate messagingTemplate;
|
||||
private final MessageCacheService messageCacheService;
|
||||
|
||||
@EventListener
|
||||
public void handlePositionUpdate(PositionUpdateEvent event) {
|
||||
WebSocketMessage<PositionData> message = createMessage("position_update", event.getPayload());
|
||||
|
||||
// 立即推送到前端
|
||||
messagingTemplate.convertAndSend("/topic/positions", message);
|
||||
|
||||
// 缓存消息用于重连恢复
|
||||
messageCacheService.cacheMessage(message);
|
||||
}
|
||||
|
||||
@EventListener
|
||||
public void handleCollisionWarning(CollisionWarningEvent event) {
|
||||
WebSocketMessage<CollisionData> message = createMessage("collision_warning", event.getPayload());
|
||||
|
||||
// 高优先级消息立即推送
|
||||
messagingTemplate.convertAndSend("/topic/alerts", message);
|
||||
messageCacheService.cacheMessage(message);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 5. 统一消息推送 (控制台接收所有消息)
|
||||
|
||||
**单一推送主题**
|
||||
- `/topic/realtime` - 所有实时消息统一推送到控制台
|
||||
|
||||
**消息路由优化**
|
||||
```java
|
||||
@Component
|
||||
public class UnifiedMessageBroadcaster {
|
||||
|
||||
@EventListener
|
||||
public void handleAnyWebSocketEvent(WebSocketEvent event) {
|
||||
WebSocketMessage<?> message = createStandardMessage(event);
|
||||
|
||||
// 统一推送到控制台主题
|
||||
messagingTemplate.convertAndSend("/topic/realtime", message);
|
||||
|
||||
// 缓存用于重连恢复
|
||||
messageCacheService.cacheMessage(message);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 6. 高性能实时推送优化
|
||||
|
||||
**实时性优化**
|
||||
- 事件监听器使用同步处理，确保实时推送
|
||||
- 移除不必要的异步处理和批量操作
|
||||
- 数据处理完成后立即发布事件，立即推送
|
||||
|
||||
**消息缓存策略 (仅用于重连恢复)**
|
||||
```java
|
||||
@Service
|
||||
public class MessageCacheService {
|
||||
private final RedisTemplate<String, Object> redisTemplate;
|
||||
|
||||
// 缓存最近的消息，用于客户端重连后恢复
|
||||
public void cacheMessage(WebSocketMessage<?> message) {
|
||||
String key = "websocket:messages:" + message.getType();
|
||||
redisTemplate.opsForList().leftPush(key, message);
|
||||
redisTemplate.opsForList().trim(key, 0, 99); // 保留最近100条消息
|
||||
redisTemplate.expire(key, Duration.ofMinutes(30)); // 30分钟过期
|
||||
}
|
||||
|
||||
// 客户端重连后获取遗漏消息
|
||||
public List<WebSocketMessage<?>> getRecentMessages(String messageType, int count) {
|
||||
String key = "websocket:messages:" + messageType;
|
||||
return redisTemplate.opsForList().range(key, 0, count - 1);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**连接管理优化**
|
||||
- 简化连接管理，专注于控制台单一客户端
|
||||
- 心跳检测和断线重连机制
|
||||
- 重连后自动推送遗漏消息
|
||||
|
||||
### 优化后的架构优势
|
||||
|
||||
1. **简化高效**: 扁平化事件架构，减少不必要的层次
|
||||
2. **实时性强**: 同步事件处理，数据处理完成立即推送
|
||||
3. **专注控制台**: 统一消息推送，适合当前业务需求
|
||||
4. **可靠恢复**: Redis缓存支持重连后消息恢复
|
||||
5. **易于扩展**: 未来增加订阅机制时可平滑升级
