SpringBoot 集成 MQTT 并发发送消息异常有大佬帮忙看看吗

我在 github 搜索到一个有点年头了但是可能有关的 issue ，这个 issue 已经关闭了，本来还想留言来着 https://github.com/eclipse/paho.mqtt.java/issues/323
我使用 Spring-Integration-mqtt 模块发送和接收 MQTT 消息，发生以下异常：

2024-10-22 10:56:45.161 [][] ERROR o.s.i.handler.LoggingHandler:250 - org.springframework.messaging.MessageHandlingException: Failed to publish to MQTT in the [bean 'mqttOutboundHandler' for component 'mqttOutboundFlow.org.springframework.integration.config.ConsumerEndpointFactoryBean#1'; defined in: 'class path resource [com/rms/config/mqtt/MqttConfig.class]'; from source: 'com.rms.config.mqtt.MqttConfig.mqttOutboundHandler(org.eclipse.paho.mqttv5.client.MqttConnectionOptions)'], failedMessage=GenericMessage [payload={"value":[],"unitId":741,"fieldName":"landingCall-down-front-1-32","isRunningData":false,"isError":false}, headers={replyChannel=nullChannel, errorChannel=, mqtt_qos=0, id=1237ba75-e408-10ff-e322-5f692dd8970e, mqtt_topic=status/741/landingCall-down-front-1-32, timestamp=1729565799271}]

SpringBoot 3.2.5

PahoMQTT1.2.5 下面是我的核心逻辑。我使用 Spring-Integration 集成流程配置了两个 Mqtt 客户端。一个用于接收信息，另一个用于发送消息。发送消息的频率约为每秒 5000 条消息。

mqtt:
  client-id-inbound: rms-inbound
  client-id-outbound: rms-outbound
  url: tcp://127.0.0.1:1883
  username: rms
  password: 123456

import java.util.concurrent.Executors;

@IntegrationComponentScan("com.rms.config")

@ConfigurationProperties(prefix = "mqtt")
@Data
public class MqttConfig {
    private String clientIdInbound;
    private String clientIdOutbound;
    private String url;
    private String password;
    private String username;
    @Bean
    public MqttConnectionOptions mqttConnectOptions(){
        MqttConnectionOptions options = new MqttConnectionOptions();
        options.setServerURIs(new String[] { url});
        options.setUserName(username);
        options.setPassword(password.getBytes());
        options.setAutomaticReconnect(true);
        return options;
    }
    @Bean
    public ClientManager<IMqttAsyncClient, MqttConnectionOptions> clientManager(MqttConnectionOptions options) {
        Mqttv5ClientManager clientManager = new Mqttv5ClientManager(options, clientIdInbound);

}

@Slf4j
@RequiredArgsConstructor
public class UnitErrorHandler implements MessageHandler {
    private final LogService logService;

    @Override
    public void handleMessage(Message<?> message) throws MessagingException {
        Prop<?> prop = (Prop<?>) message.getPayload();
        logService.saveErrorLog(prop);
    }

}

我使用 MessagingGateway 注释将消息定向到我的 mqttOutboundChannel ，以便我可以使用 MqttGateway 发送 mqtt 消息


@MessagingGateway(defaultRequestChannel = "mqttOutboundChannel")
public interface MqttGateway {
    void sendToMqtt(String data);

    void sendToTopic(String payload, @Header(MqttHeaders.TOPIC)String topic);

    void sendToTopic(String payload, @Header(MqttHeaders.TOPIC)String topic,@Header(MqttHeaders.QOS ) int qos);
    void sendWithResp(String payload, @Header(MqttHeaders.TOPIC)String topic,@Header(MqttHeaders.RESPONSE_TOPIC) String responseTopic,@Header(MqttHeaders.QOS ) int qos);
}

当消息投递率很低，一般每秒不到 200 条消息时，我一开始提到的错误就不会出现，但是当我将消息投递率提高到 5000 条时，按照上面的配置就开始出现报错，另外如果我去掉了 mqtt 消息的入站部分，也就是上面的代码中引入的 statusInboundFlow 集成 Flow 后发送消息又不报错了
