Spring Boot Auto-Configuration

The starter supports 11 options, which are listed below.

Name Description Default Type

camel.component.azure-iothub.autowired-enabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

Boolean

camel.component.azure-iothub.configuration

The shared component configuration. The option is a org.apache.camel.component.azure.iothub.IoTHubConfiguration type.

IoTHubConfiguration

camel.component.azure-iothub.connection-string

The IoT Hub device connection string. Can be overridden per message via the CamelAzureIoTHubConnectionString header.

String

camel.component.azure-iothub.content-type

Content type applied to telemetry messages.

application/json

String

camel.component.azure-iothub.delivery-mode

How the message body is delivered: telemetry, device twin reported properties, or both.

telemetry

IoTHubDeliveryMode

camel.component.azure-iothub.device-client-eviction-interval

How often the pool is scanned for idle device clients to evict.

30000ms

Duration

camel.component.azure-iothub.device-client-idle-timeout

Idle time after which a pooled device client is evicted and closed.

300000ms

Duration

camel.component.azure-iothub.enabled

Whether to enable auto configuration of the azure-iothub component. This is enabled by default.

Boolean

camel.component.azure-iothub.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

Boolean

camel.component.azure-iothub.protocol

The protocol used to connect to Azure IoT Hub.

mqtt

IotHubClientProtocol

camel.component.azure-iothub.send-timeout

Timeout for telemetry sends and twin reported-property updates.

10000ms
