Spring Bean Alias in JavaConfig

Question

I have a @Service annotated class which provides core functionality which I can use in all my projects:

@Service
public class MyService {}
         


        

Answer 1

If you want to use the placeholder, another workaround is to use @Bean in a @Configuration class using @Value and the Spring applicationContext.

@Configuration
public class AppConfig {

    @Autowired
    private ApplicationContext context;

    @Bean
    public MyService myService(@Value("${myService.qualifier}") String qualifier) {
        return (MyService) context.getBean(qualifier);
    }
}

NB : special consideration must be taken for the placeholder bean which must be loaded at the beginning (cf javadoc)
