Annotation Interface ConfigurationProperties

@Singleton
@Documented
@Retention(RUNTIME)
@Target({TYPE,ANNOTATION_TYPE,METHOD,CONSTRUCTOR})
@ConfigurationReader
public @interface ConfigurationProperties

Defines a singleton bean whose property values are resolved from a PropertyResolver.

The PropertyResolver is typically the Micronaut Environment.

The value() of the annotation is used to indicate the prefix where the configuration properties are located. The class can define properties or fields which will have the configuration properties to them at runtime.

Complex nested properties are supported via classes that are public static inner classes and are also annotated with ConfigurationProperties.
