Role (Spring Framework 4.3.30.RELEASE API)

```
@Target({TYPE,METHOD})
@Retention(RUNTIME)
@Documented
public @interface Role
```
Indicates the 'role' hint for a given bean.
May be used on any class directly or indirectly annotated with Component or on methods annotated with Bean.
If this annotation is not present on a Component or Bean definition, the default value of BeanDefinition.ROLE_APPLICATION will apply.
If Role is present on a @Configuration class, this indicates the role of the configuration class bean definition and does not cascade to all @Bean methods defined within. This behavior is different than that of the @Lazy annotation, for example.
