Create prototype scoped Spring bean with annotations?

Question

Is it possible to convert the following XML configuration to an annotation based one?

<bean id="myBean" class="my.package.MyBeanClass" scope="prototype" />

I'm using Spring 2.5.6.

You can use the @Scope(value = ConfigurableBeanFactory.SCOPE_PROTOTYPE) annotation.

@Service
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public class CustomerService {
    // ...
}

There's also a nice constant to use instead of the String: [`BeanDefinition.SCOPE_PROTOTYPE`](http://static.springsource.org/spring/docs/2.5.3/api/org/springframework/beans/factory/config/BeanDefinition.html#SCOPE_PROTOTYPE) – Nov 29 '12 at 10:25

In the Scope annotation Javadoc, the constant recomeded is [ConfigurableBeanFactory.SCOPE_PROTOTYPE](http://docs.spring.io/spring/docs/3.2.5.RELEASE/javadoc-api/org/springframework/beans/factory/config/ConfigurableBeanFactory.html#SCOPE_PROTOTYPE) – jfcorugedo Jan 28 '14 at 17:33
Has BeanDefinition class removed in Spring 4 ? – Mushtaq Jameel Jun 06 '14 at 12:14

@Scope(value = ConfigurableBeanFactory.SCOPE_PROTOTYPE) – ameet chaubal Feb 26 '15 at 15:30
Or save a little typing with `@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)` – mjaggard Dec 12 '17 at 13:55
Is there any reasoning behind the fact that there is a `@RequestScope` annotation but no `@PrototypeScope`? – Peter Wippermann Sep 26 '18 at 10:46

As of the current spring version 4.3.2, we can use @Scope("prototype") annotation.

@Scope("prototype")
@Repository
public class MovieFinderImpl implements MovieFinder {
    // ...
}

I'd say using a provided constant, as in the accepted answer, is better. – herman Jan 12 '17 at 12:37
@herman What makes it better? And is there a JSR standard for this? – Steve Mar 05 '17 at 22:25

@Steve in case the string changes (not very likely) or you want to search for references using your IDE – herman Mar 06 '17 at 08:02
