@Configuration, @Component and scope

[slowikps]

Hi,
I am just wondering why this part of code:

@Configuration
public class AppConfig {

@Bean
@Scope(value = WebApplicationContext.SCOPE_REQUEST, proxyMode = ScopedProxyMode.TARGET_CLASS)
public SomeClass getSomeClass(){
…
}
}

does not work. However this is legall:

@Component
@Scope(value = WebApplicationContext.SCOPE_REQUEST, proxyMode = ScopedProxyMode.TARGET_CLASS)
public class SomeClass {
…
}

Why it is forbidden to create bean with scope request in class annotated as Configuration?
