Hi,

We are using AbpRabbitMqModule, AbpEventBusRabbitMqModule modules for eventbus messaging . We want to update AbpRabbitMqOptions HostName at runtime with user input. We are using appsettings.json to configuration.
Is updating appsettings.json enough ?

I attached related part of our code .What is the best way to do that?
Is there a way to reconfigure a module at runtime and reinitialize it?

Thanks a lot.

HI,

You can inject the IOptions<AbpRabbitMqOptions> to change it.

Hi liangshiwei,

Thx for your answer, I have tried IOptions and IOptionsSnapshot also.
We can update value, but connections is not refreshed or updated with new hostname.
Am i missing something ?

Regards.

Hi,

The connection is not cheeped, so we use IConnectionPool. it will reuse as many connections as possible.

You can replace IConnectionPool with your own implementation to create a new connection when the HostName is changed.
