Annotation Type ServiceScan

@Retention(value=RUNTIME)
@Target(value=TYPE)
@Documented
@Import(value=ServiceScanConfiguration.class)
public @interface ServiceScan

Add this annotation to an @Configuration class to have the services bound to the app scanned and bean for each one added to the application context:

 @Configuration
 @ServiceScan
 public class CloudConfiguration {
     // may (optionally) extend AbstractCloudConfiguration
 }
 

This annotation is similar to @ComponentScan in Spring, which scans for classes with the @Component classes and creates a bean for each. @ServiceScan, in the same spirit, scans services bound to the app and creates a bean for each. Upon service scanning, if there is a unique bean of for service type, you can inject it using the following code (shows Redis, but the same scheme works for all services):

 @Autowired RedisConnectionFactory redisConnectionFactory;
 

If there are more than one services of a type, you can use the @Qualifier annotation as in the following code:

 @Autowired @Qualifier("service-name1") RedisConnectionFactory redisConnectionFactory;
 @Autowired @Qualifier("service-name2") RedisConnectionFactory redisConnectionFactory;
