Annotation Type Required

@Retention(value=RUNTIME)
@Target(value=METHOD)
public @interface Required

Marks a method (typically a JavaBean setter method) as being 'required' (i.e. the (setter) method must be configured to be dependency injected with a value).

Please do consult the Javadoc for the RequiredAnnotationBeanPostProcessor class (which, by default, checks for the presence of this annotation).
