Injecting data using @Value into @Configurable classes

[Iassan]

Hi,

I'm trying to inject String using @Value into @Configurable class. Class itself is a JSF Converter, and therefore is not Spring managed. That's why I'm using @Configurable. Trick is, can I do that injection without defining prototype bean in my XML? Without prototype I get:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'pl.wroc.jug.jb.web.converter.DateConverter' is defined

With prototype everything works as expected. My problem is: why I have to define this prototype when injecting using @Value, while when injecting using @Inject or @Autowire can do without prototype? Is it a feature or a bug? My prototype doesn't do anything interesting:

<bean class="pl.wroc.jug.jb.web.converter.DateConverter" scope="prototype"/>

Best regards

@Value is replaced using a BeanFactoryPostProcessor which is only run BEFORE bean creation. Spring doesn't control the creation and hence cannot do anything with the @Value.

@Autowired by default does dependency injection by type, if you use @Configurable it checks the application context and let that do autowiring. Now if you have a prototype bean of the same type of your @Configurable defined it is going to use that as the blue print to wire/configure your new bean.

So it is neither a undocumented feature nor a bug it is the way an ApplicationContext works.

Is this now possible in Spring 3? Is there any trickery I can use to get @Value to work with @Configurable?
