Annotation Interface PostInject

@Target(METHOD)
@Retention(RUNTIME)
public @interface PostInject

Marks a method to be invoked after configuration field injection has completed.

Methods annotated with @PostInject are called after all @Key annotated fields have been populated from the configuration file. Useful for validation, computing derived properties, or other post-loading initialization.

Examples:

 @PostInject
 private void updateDerivedProperties() {
     this.serverUrl = "http://" + host + ":" + port;
 }

 @PostInject
 private void validateConfiguration() {
     if (port < 1 || port > 65535) {
         throw new IllegalArgumentException("Port must be between 1 and 65535");
     }
 }
 

Requirements: Methods must take no parameters. Multiple methods per class are allowed. Execution order is not guaranteed.
