/**
 * Indicates the 'role' hint for a given bean.

 * 

May be used on any class directly or indirectly annotated with * {@link org.springframework.stereotype.Component} or on methods * annotated with {@link Bean}. * *

If this annotation is not present on a Component or Bean definition, * the default value of {@link BeanDefinition#ROLE_APPLICATION} will apply. * *

If Role is present on a {@link Configuration @Configuration} class, * this indicates the role of the configuration class bean definition and * does not cascade to all @{@code Bean} methods defined within. This behavior * is different than that of the @{@link Lazy} annotation, for example. * * @author Chris Beams * @since 3.1 * @see BeanDefinition#ROLE_APPLICATION * @see BeanDefinition#ROLE_INFRASTRUCTURE * @see BeanDefinition#ROLE_SUPPORT * @see Bean */ @Target({ElementType.TYPE, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) @Documented public @interface Role { /** * Set the role hint for the associated bean. * @see BeanDefinition#ROLE_APPLICATION * @see BeanDefinition#ROLE_INFRASTRUCTURE * @see BeanDefinition#ROLE_SUPPORT */ int value(); }
