Annotation Interface ConfigurationProperties

@Target({TYPE,METHOD}) @Retention(RUNTIME) @Documented @Indexed public @interface ConfigurationProperties
Annotation for externalized configuration. Add this to a class definition or a @Bean method in a @Configuration class if you want to bind and validate some external Properties (e.g. from a .properties file).

Binding is either performed by calling setters on the annotated class or, if @ConstructorBinding is in use, by binding to the constructor parameters.

Note that contrary to @Value, SpEL expressions are not evaluated since property values are externalized.

      Default:
      false
