java.lang.Object

org.springframework.boot.context.properties.bind.AbstractBindHandler

com.broadleafcommerce.cloudstream.binding.CustomSuffixBindHandler

All Implemented Interfaces:

org.springframework.boot.context.properties.bind.BindHandler

public class CustomSuffixBindHandler
extends org.springframework.boot.context.properties.bind.AbstractBindHandler

Custom Spring BindHandler to support dynamic re-naming of Spring Cloud Stream BindingProperties at runtime. This supports use cases where there is a need to share a single message broker instance across multiple environment specific or region specific application instances. To facilitate segmenting destinations and groups for each environment, this custom bind handler allows modifying each ALREADY DEFINED Spring Cloud Stream destination and group definitions with a particular suffix to allow segmentation across environments via a property. e.g. if you had existing bindings already defined like: spring.cloud.stream.binding.input.destination=topic spring.cloud.stream.binding.input.group=subscription Assuming the appropriate SUFFIX is configured CustomCloudstreamBindingConfiguration, this custom bind handler will modify the properties and bind the following: "topic-SUFFIX" and "subscription-SUFFIX" instead
