<beans>
	<context:annotation-config/>
	<bean class="com.foo.AppConfig"/>
</beans>

Where 'AppConfig' is a @Configuration class:

@Configuration
public class AppConfig {
        public @Bean Foo foo() {
                return new Foo();
        }
}

The application would then be bootstrapped as follows:

ApplicationContext context = new ClassPathApplicationContext("app-config.xml");
Foo foo = context.getBean("foo", Foo.class);
