Interacting with Configuration Properties

If you would like to use ConfigurationProperties to configure the behavior of your DSL/Initializer, it is best practice to bind the ConfigurationProperties to your environment, but also expose the ConfigurationProperties to the DSL to allow programmatic default overrides. To do this, first add the ConfigurationProperties to your DSL.

Example

class ExampleDsl : SpringDsl {
    internal var defaults: ExampleConfig = ExampleConfig()
    fun defaults(config: ExampleConfig.() -> Unit){
        defaults.apply(config)
    }
}

Then, in your initializer, register the ConfigurationProperties using the helper provided by the spring-funk-runtimeconfig package

Example

val defaultInstance = applicationContext.getDsl<ExampleDsl>()?.defaults
applicationContext.registerRuntimeConfig<ExampleConfig>(defaultInstance = defaultInstance)

Then use the config in your bean using another helper from spring-funk-runtimeconfig

Example

applicationContext.registerBean<MyBean>{ 
    MyBean(applicationContext.getRuntimeConfig<ExampleConfig>()) 
}

Following this method, the configuration properties will be consolidated such that properties from the Environment override the code defaults supplied in the DSL.
