好的,针对您的问题,我可以给出以下步骤:
1. 添加依赖
在 pom.xml 文件中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-integration</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-mqtt</artifactId>
</dependency>
```
2. 配置 MQTT 连接信息
在 application.properties 文件中添加以下配置:
```properties
spring.mqtt.username=your-username
spring.mqtt.password=your-password
spring.mqtt.url=tcp://your-mqtt-server:1883
```
3. 创建 MQTT 连接工厂
在代码中创建 MQTT 连接工厂:
```java
@Bean
public MqttPahoClientFactory mqttClientFactory() {
DefaultMqttPahoClientFactory factory = new DefaultMqttPahoClientFactory();
MqttConnectOptions options = new MqttConnectOptions();
options.setUserName(username);
options.setPassword(password.toCharArray());
factory.setConnectionOptions(options);
return factory;
}
```
4. 创建 MQTT 消息通道
在代码中创建 MQTT 消息通道:
```java
@Bean
public MessageChannel mqttInputChannel() {
return new DirectChannel();
}
```
5. 创建 MQTT 消息适配器
在代码中创建 MQTT 消息适配器:
```java
@Bean
public MessageProducer inbound() {
MqttPahoMessageDrivenChannelAdapter adapter =
new MqttPahoMessageDrivenChannelAdapter("clientId", mqttClientFactory(), "topic");
adapter.setCompletionTimeout(5000);
adapter.setConverter(new DefaultPahoMessageConverter());
adapter.setQos(1);
return adapter;
}
```
6. 处理 MQTT 消息
在代码中处理 MQTT 消息:
```java
@ServiceActivator(inputChannel = "mqttInputChannel")
public void handleMessage(String message) {
// 处理消息
}
```
