我的服务使用paho mqtt时出现问题。它超时但没有连接丢失的报告。有没有人有解决这个问题的办法？如何解决此问题mqtt Paho超时但未报告连接丢失

public void connect(String client_id) {

String tmpDir = System.getProperty("java.io.tmpdir");

MqttDefaultFilePersistence dataStore = new MqttDefaultFilePersistence(tmpDir);

MqttConnectOptions options = new MqttConnectOptions();

options.setKeepAliveInterval(120);

try {

_client = new MqttClient(_url, MqttClient.generateClientId(), dataStore);

_client.connect(options);

_client.setCallback(this);

_client.subscribe(TOPIC);

LOGGER.info("Subscribed to " + Arrays.toString(TOPIC));

LOGGER.info("MAX CORES " + MAX_CORES);

} catch (MqttException e) {

LOGGER.log(Level.INFO, "Mosquitto Error: " + e.fillInStackTrace());

connect(null);

}

}

@Override

public void messageArrived(final String topic, final MqttMessage message) throws Exception {

threadPool.execute(new Runnable(){// code});

}

使用MQTT v 1.0.0

你将不得不给我们一些更多的上下文给任何人来帮助。诸如此类，它是否超时作为连接的一部分，或者经过一段时间不发送数据之后？您设置了什么KeepAlive期限？ –

原来是60秒，现在我改为120秒 –

在这个问题上有什么好运？ –
