Annotation Type Required

Deprecated.

as of 5.1, in favor of using constructor injection for required settings (or a custom InitializingBean implementation)

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

Marks a method (typically a JavaBean setter method) as being 'required': that is, 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).

2.0
