Apply a dynamic group value in Spring Cloud Stream

How could I give a group value to the stream binders dynamically, for flexibility while using Spring Cloud Stream. How can I achieve this?

Solution

  • Spring Boot configuration properties can use property placeholder to be based on other properties or environment variables.

    So, the mentioned spring.cloud.stream.bindings.<bindingName>.group can be something like this:

    spring.cloud.stream.bindings.MY_INPUT_QUEUE.group=${my.envvar}

    This way you can rely on something what is relevant to the environment where your service has started.
