+=== Dumping Configuration Properties
+

+
+[source,groovy,indent=0,options="nowrap"]
+----
+def mc = ctx.getBean(com.agorapulse.micronaut.grails.MicronautContextHolder).context
+def env = mc.environment
+def sources = env.propertySources
+
+
+for (source in sources) {
+ println "$source.name:"
+ for (name in source) {
+ def value = source.get(name)
+ println " $name (${value?.getClass()}): ${String.valueOf(value)}" 
+ }
