Allow a last-will message (and topic) to be configured.
How can the following configuration be coded? I keep getting NULL pointer exception "Failed to instantiate [com.amazonaws.services.iot.client.AWSIotMqttClient]: Factory method 'awsIotMqttClient' threw exception; nested exception is java.lang.NullPointerException" .
I think the NULL pointer exception is due to not configuring the below properly
xortalk:
iot:
client:
aws:
endpoint: yourendpoint.iot.eu-central-1.amazonaws.com
client-id: ixortalk-iot-client-${random.int}
default-topic: sdk/test/java
certificate-file: /etc/aws_iot/certificate.pem.crt
private-key-file: /etc/aws_iot/private.pem.key
An optional timeout can be specified when publishing messages.
Fetching real-time connection string from the database when required. Because spring server won't start without valid connection string.
When the AWS IoT Client cannot connect, it shouldn't block the application startup. When the connection is possible again, it will recover anyway.
by default it seems to run for azure. are there instructions to build and run for AWS IOT?
Publish objects as payload which will be mapped to json via the ObjectMapper internally, similar to listener.
As the title says, how do I specify the quality of service? Great library btw, thanks!
