| Property |
Default |
Description |
| host |
tcp://127.0.0.1:1883 |
The URI of the MQTT broker to connect too - this component also supports SSL - e.g. ssl://127.0.0.1:8883 |
| localAddress |
|
The local InetAddress and port to use |
| connectAttemptsMax |
-1 |
The maximum number of attempts to establish an initial connection - -1 in infinite. |
| reconnectAttemptsMax |
-1 |
The maximum number of attempts to re-establish a connection after failure - -1 in infinite. |
| reconnectDelay |
10 |
The time in milliseconds between attempts to reestablish an initial or failed connection |
| reconnectBackOffMultiplier |
2.0 |
The multiplier to use to the delay between connection attempts for successive failed connection attempts |
| reconnectDelayMax |
30000 |
The maximum time in milliseconds between a new attempt to establish a connection. So even using the reconnectBackOffMultiplier, this property will define the maximum delay before another connection attempt to the MQTT broker |
| qualityOfService |
AtLeastOnce |
The MQTT Quality of Service to use for message exchanges. It can be one of AtMostOnce, AtLeastOnce or ExactlyOnce |
| subscribeTopicName |
|
The name of the Topic to subscribe to for messages |
| publishTopicName |
camel/mqtt/test |
The default Topic to publish messages on |
| byDefaultRetain |
false |
The default retain policy to be used on messages sent to the MQTT broker |
| mqttTopicPropertyName |
MQTTTopicPropertyName |
The property name to look for on an Exchange for an individual published message. If this is set - the name will be used as the Topic to publish a message to the MQTT message broker. This option is removed since camel 2.14.0. Since Camel 2.14.0, Camel uses "CamelMQTTSubscribeTopic" as to store the topic property name of the MQTT consumer into the message header, and "CamelMQTTPublishTopic" as to look up the topic property name of the MQTT producer from the message header. |
| mqttRetainPropertyName |
MQTTRetain |
The property name to look for on an Exchange for an individual published message. If this is set (expects a Boolean value) - then the retain property will be set on the message sent to the MQTT message broker. |
| mqttQosPropertyName |
MQTTQos |
The property name to look for on an Exchange for an individual published message. If this is set (one of AtMostOnce, AtLeastOnce or ExactlyOnce ) - then that QoS will be set on the message sent to the MQTT message broker. |
| connectWaitInSeconds |
10 |
Delay in seconds the Component will wait for a connection to be established to the MQTT broker |
| disconnectWaitInSeconds |
5 |
the number of seconds the Component will wait for a valid disconnect on stop() from the MQTT broker |
| sendWaitInSeconds |
5 |
The maximum time the Component will wait for a receipt from the MQTT broker to acknowledge a published message before throwing an exception |
