# DJI MQTT 模块使用说明(支持多客户端)
## 概述
本模块实现了大疆MQTT消息的接收和处理功能支持动态创建多个MQTT客户端每个客户端可以连接到不同的服务器。
## 核心特性
**多客户端支持** - 可以同时创建多个MQTT客户端
**动态配置** - 每个客户端可以独立配置IP、端口、用户名等
**独立消息处理** - 每个客户端有独立的消息处理器
**共享订阅可选** - 支持开启/关闭共享订阅
**完整数据模型** - 包含所有无人机和机场字段
**自动区分设备** - 自动识别无人机和机场数据
## 架构设计
```
DjiMqttClientManager (管理器)
DjiMqttClientService (客户端实例)
DjiMqttMessageHandler (消息处理器)
IDroneDataCallback / IDockDataCallback (回调接口)
```
## 快速开始
### 1. 注入管理器
```java
@Autowired
private DjiMqttClientManager clientManager;
```
### 2. 创建客户端
```java
// 构建配置
DjiMqttClientConfig config = DjiMqttClientConfig.builder()
.host("mqtt.t-aaron.com") // MQTT服务器地址
.port(10883) // 端口
.clientId("my_client_1") // 客户端ID必须唯一
.username("admin") // 用户名
.password("admin") // 密码
.useSharedSubscription(true) // 是否使用共享订阅
.sharedGroupName("dji-group") // 共享订阅组名
.build();
// 创建并连接客户端
String clientId = clientManager.createClient(config);
```
### 3. 注册回调
```java
// 获取消息处理器
DjiMqttMessageHandler handler = clientManager.getHandler(clientId);
// 注册无人机数据回调
handler.registerDroneDataCallback(droneData -> {
System.out.println("无人机SN: " + droneData.getDeviceSn());
System.out.println("位置: " + droneData.getLatitude() + ", " + droneData.getLongitude());
});
// 注册机场数据回调
handler.registerDockDataCallback(dockData -> {
System.out.println("机场SN: " + dockData.getDeviceSn());
System.out.println("温度: " + dockData.getTemperature());
});
```
## 多客户端示例
### 场景同时连接多个MQTT服务器
```java
@Component
public class MyMqttService {
@Autowired
private DjiMqttClientManager clientManager;
public void init() {
// 客户端1连接到服务器A
DjiMqttClientConfig config1 = DjiMqttClientConfig.builder()
.host("mqtt.server-a.com")
.port(10883)
.clientId("client_a")
.username("admin")
.password("admin")
.useSharedSubscription(true)
.build();
String clientId1 = clientManager.createClient(config1);
DjiMqttMessageHandler handler1 = clientManager.getHandler(clientId1);
handler1.registerDroneDataCallback(data -> processServerA(data));
// 客户端2连接到服务器B
DjiMqttClientConfig config2 = DjiMqttClientConfig.builder()
.host("mqtt.server-b.com")
.port(1883)
.clientId("client_b")
.username("user2")
.password("pass2")
.useSharedSubscription(false)
.build();
String clientId2 = clientManager.createClient(config2);
DjiMqttMessageHandler handler2 = clientManager.getHandler(clientId2);
handler2.registerDroneDataCallback(data -> processServerB(data));
}
}
```
## 管理器API
### 创建客户端
```java
String clientId = clientManager.createClient(config);
```
### 获取消息处理器
```java
DjiMqttMessageHandler handler = clientManager.getHandler(clientId);
```
### 获取客户端
```java
DjiMqttClientService client = clientManager.getClient(clientId);
boolean isConnected = client.isConnected();
```
### 移除客户端
```java
clientManager.removeClient(clientId);
```
### 断开所有客户端
```java
clientManager.disconnectAll();
```
### 获取所有客户端ID
```java
Set<String> clientIds = clientManager.getAllClientIds();
```
## 配置参数说明

|------|------|------|--------|------|
| host | String | 是 | - | MQTT服务器地址 |
| port | Integer | 是 | - | MQTT服务器端口 |
| clientId | String | 是 | - | 客户端ID必须唯一 |
| username | String | 是 | - | 用户名 |
| password | String | 是 | - | 密码 |

## 数据模型
### DroneData无人机数据
包含100+字段,主要分类:
- **基础信息**:固件版本、飞行器状态、档位等
- **位置信息**经纬度、高度、Home点等
- **姿态信息**:偏航角、横滚角、俯仰角
- **速度信息**:水平速度、垂直速度、风速
- **电池信息**:电量、剩余飞行时间、电池详情
- **相机信息**:拍照录像状态、变焦、红外测温等
- **避障信息**:水平/上视/下视避障状态
- **保养信息**:保养状态、累计飞行时间/架次
### DockData机场数据
包含60+字段,主要分类:
- **基础信息**:固件版本、机场状态、任务状态
- **位置信息**:经纬度、高度、朝向角
- **环境信息**:温度、湿度、风速、降雨量
- **设备状态**:舱盖状态、飞行器在舱状态、补光灯等
- **电池信息**:充电状态、备用电池、电池保养
- **网络信息**:网络类型、质量、速率
- **图传信息**4G/SDR链路状态、信号质量
## 注意事项
1. **clientId必须唯一**每个MQTT客户端的clientId必须全局唯一
2. **部分字段推送**每次MQTT消息可能只包含部分字段使用时需要判空
3. **原始数据访问**:所有字段都保存在`rawData`中可以通过Map访问
4. **共享订阅**:多实例部署时建议开启共享订阅,避免重复消费
5. **独立处理器**:每个客户端有独立的消息处理器,互不影响
6. **自动重连**:连接断开后会自动重连(可配置)

┌─────────────────────────────────────────────────────────────────┐
│ 步骤1: 节点A 执行命令并注册回调 │
└─────────────────────────────────────────────────────────────────┘
节点A: executeCommand(TAKE_OFF)
节点A: registerCallback(topic="dji/SN9527/response", ...)
节点A: MqttCallbackStore.registerCallback()
Redis: 存储回调信息(使用两个 Key 的原因:性能优化)
【Key 1】回调详细信息Hash 结构)
- Key: mqtt:callback:{callbackId}
- Value: {callbackId, topic, nodeId="nodeA", timeoutMs, registerTime, ...}
- 作用: 存储单个回调的完整信息
- 查询: O(1) 时间复杂度,通过 callbackId 直接获取
【Key 2】Topic 索引Set 结构)
- Key: mqtt:topic:dji/SN9527/response
- Value: Set<callbackId> // 例如: ["abc-123", "def-456", "ghi-789"]
- 作用: 快速查询等待某个 topic 的所有回调
- 查询: O(1) 时间复杂度,直接获取 callbackId 列表
【为什么需要两个 Key
如果只用一个 Key 存储所有回调,查询时需要遍历所有回调并过滤 topic
时间复杂度为 O(n)。使用 Topic 索引后,可以直接获取目标回调列表,
时间复杂度降为 O(1),大幅提升性能。
【示例】
假设有 3 个回调:
- callbackId="abc-123", topic="dji/SN9527/response", nodeId="nodeA"
- callbackId="def-456", topic="dji/SN9527/state", nodeId="nodeB"
- callbackId="ghi-789", topic="dji/SN9527/response", nodeId="nodeA"
Redis 存储结构:
mqtt:callback:abc-123 → {callbackId:"abc-123", topic:"dji/SN9527/response", nodeId:"nodeA"}
mqtt:callback:def-456 → {callbackId:"def-456", topic:"dji/SN9527/state", nodeId:"nodeB"}
mqtt:callback:ghi-789 → {callbackId:"ghi-789", topic:"dji/SN9527/response", nodeId:"nodeA"}
mqtt:topic:dji/SN9527/response → ["abc-123", "ghi-789"]
mqtt:topic:dji/SN9527/state → ["def-456"]
查询 topic="dji/SN9527/response" 的回调:
1. 从索引获取: SMEMBERS mqtt:topic:dji/SN9527/response → ["abc-123", "ghi-789"]
2. 批量获取详情: MGET mqtt:callback:abc-123 mqtt:callback:ghi-789
3. 总耗时: O(1) + O(k)k 是该 topic 的回调数量(通常很小)
【Redis 数据清理时机】
Redis 中的回调数据有两种清理机制:
┌─────────────────────────────────────────────────────────────┐
│ 1⃣ 主动清理(业务逻辑触发) │
└─────────────────────────────────────────────────────────────┘
触发时机:
✅ 回调成功执行后TransactionExecutor 的 finally 块)
✅ 回调超时后TransactionExecutor 的 finally 块)
✅ handleMessage 检测到超时(转发前检查)
清理操作:
unregisterCallback(callbackId)
1. 获取回调信息: GET mqtt:callback:{callbackId}
2. 删除回调信息: DEL mqtt:callback:{callbackId}
3. 从索引中移除: SREM mqtt:topic:{topic} {callbackId}
示例:
T0: 注册回调,超时时间 10 秒
T5: 收到 MQTT 响应,回调执行成功
T5: 立即清理 Redis 数据 ✅
- DEL mqtt:callback:abc-123
- SREM mqtt:topic:dji/SN9527/response abc-123
┌─────────────────────────────────────────────────────────────┐
│ 2⃣ 被动清理Redis TTL 自动过期) │
└─────────────────────────────────────────────────────────────┘
作用:兜底机制,防止异常情况下的数据残留
设置方式:
// 注册回调时设置 TTL
SET mqtt:callback:{callbackId} {json} EX 3600 // 1小时后自动过期
EXPIRE mqtt:topic:{topic} 3600 // 1小时后自动过期
触发时机:
⚠️ 应用异常崩溃,主动清理未执行
⚠️ 网络分区,无法删除 Redis 数据
⚠️ 代码 Bug主动清理失败
示例:
T0: 注册回调TTL=3600秒1小时
T5: 应用崩溃,主动清理未执行 ❌
T3600: Redis 自动删除过期数据 ✅
- mqtt:callback:abc-123 自动过期删除
- mqtt:topic:dji/SN9527/response 自动过期删除
【推荐配置】
TTL 应该设置为回调超时时间的 2-3 倍,例如:
- 回调超时: 10 秒
- Redis TTL: 30 秒10秒 × 3
这样可以确保:
✅ 正常情况下,主动清理会在 10 秒内完成
✅ 异常情况下Redis 会在 30 秒后自动清理
✅ 避免设置过长的 TTL 导致内存浪费
【注意事项】
⚠️ Topic 索引的 TTL 问题:
如果同一个 topic 有多个回调,每次添加新回调时都会刷新 TTL。
这可能导致索引的 TTL 比单个回调的 TTL 更长。
解决方案:
方案1: 不为 Topic 索引设置 TTL只在删除最后一个 callbackId 时删除索引
方案2: 每次查询时过滤掉已过期的 callbackId推荐
节点A: 本地内存存储 Consumer<Object>
- localHandlers.put(callbackId, consumer)
节点A: 订阅 Redis Pub/Sub 频道
- Channel: mqtt:node:nodeA
┌─────────────────────────────────────────────────────────────────┐
│ 步骤2: MQTT Broker 将响应路由到节点B不是节点A
└─────────────────────────────────────────────────────────────────┘
MQTT Broker: 收到设备响应
MQTT Broker: 将消息路由到节点B随机/轮询)
节点B: MqttCallbackRegistry.handleMessage(topic, messageBody)
┌─────────────────────────────────────────────────────────────────┐
│ 步骤3: 节点B 从 Redis 查询等待该 topic 的回调 │
└─────────────────────────────────────────────────────────────────┘
节点B: callbackStore.getCallbacksByTopic("dji/SN9527/response")
Redis: 查询 mqtt:topic:dji/SN9527/response
Redis: 返回 Set<callbackId>
Redis: 批量获取回调信息
- mqtt:callback:{callbackId1} → {nodeId="nodeA", ...}
- mqtt:callback:{callbackId2} → {nodeId="nodeA", ...}
节点B: 获得回调列表 List<MqttCallbackInfo>
┌─────────────────────────────────────────────────────────────────┐
│ 步骤4: 节点B 判断回调属于哪个节点 │
└─────────────────────────────────────────────────────────────────┘
节点B: for (MqttCallbackInfo callback : callbacks) {
if (nodeId.equals(callback.getNodeId())) {
// 本节点的回调,直接执行
executeLocalCallback(...)
} else {
// 其他节点的回调,转发到目标节点
callbackStore.publishMessageToNode(...)
}
}
┌─────────────────────────────────────────────────────────────────┐
│ 步骤5: 节点B 通过 Redis Pub/Sub 转发消息到节点A │
└─────────────────────────────────┘
节点B: callbackStore.publishMessageToNode(
nodeId="nodeA",
callbackId="xxx",
messageBody="{...}" // JSON 字符串
)
Redis Pub/Sub: PUBLISH mqtt:node:nodeA
{
"callbackId": "xxx",
"messageBody": "{...}"
}
┌─────────────────────────────────────────────────────────────────┐
│ 步骤6: 节点A 收到 Redis Pub/Sub 消息 │
└─────────────────────────────────────────────────────────────────┘
节点A: Redis Pub/Sub Listener 收到消息
节点A: handleNodeMessage(callbackId, messageBodyJson)
节点A: 反序列化消息体
- Object messageBody = objectMapper.readValue(messageBodyJson)
节点A: executeLocalCallback(callbackId, messageBody)
节点A: 从本地内存获取 Consumer
- Consumer<Object> handler = localHandlers.get(callbackId)
节点A: 执行回调
- handler.accept(messageBody)
✅ 命令执行成功!
