Allow RabbitMQ ConnectionFactory to be customized (to set SaslConfig or enable NIO for example)

[ellac-sportsbet]

With the auto configure for rabbitmq, currently it is not possible to set SaslConfig. Currently, it always uses the default one: Plain. Could this be enhanced?

What would you like to be able to set it to? One of the DefaultSaslConfig constants (PLAIN or EXTERNAL), your own implementation of SaslConfig, JDKSaslConfig possibly with some configured mechanisms, something else?

[ellac-sportsbet]

Thanks for your quick response. As of now, I am only looking for setting it as one of the DefaultSaslConfig(more precisely, in some cases, I would like to set it to EXTERNAL). But customized implementation might be beneficial to other people as well?

We would need to setSaslConfig to DefaultSaslConfig.EXTERNAL in order to be able to do client certificate authentication with RabittMQ. At the moment this is preventing us from using spring-boot

@jimbo1007 Not sure whether you have tried a work around like below in configuration class:

@PostConstruct
public void init() {
    if (rabbitProperties.getSsl().isEnabled() && rabbitProperties.getSsl().getKeyStore() != null) {
        cachingConnectionFactory.getRabbitConnectionFactory().setSaslConfig(DefaultSaslConfig.EXTERNAL);
    }
}

I tried your workaround and it is working.
Thank you for the help
