Spring boot component scan include a single class

Question

I am using spring component scan to auto detect beans as:

@ComponentScan({"com.org.x, com.org.y"})

The issue is I want all classes in com.org.x to be scanned but I want a single class, com.org.y.SomeService.class, alone to be scanned from com.org.y

How can I achieve this ?

Also apart from using context scan, how can I created this bean and inject in the application context ?

Why use a scan if you just want a single bean. Just define your bean using an `@Bean` annotated method in your configuration class. http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#beans-java-basic-concepts — JB Nizet, Jun 10 '16 at 22:13

@Import(com.org.y.SomeService.class) works in my case (even when SomeService is a @Service, not a @Configuration)

I didn't know that one can even import `@Service`s. This is especially helpful if one can't call a constructor due to visibility restrictions. – Harold L. Brown Feb 23 '23 at 15:41

You should just define your bean using a method annotated with @Bean in your configuration class, as explained in the documentation.

What about `@Component` that has `@Autowired` fields? – Krzysztof Krasoń Mar 25 '17 at 14:59

Yep. Same for the non-default constructor: if the `SomeService` has parameters in constructor you have to copy them to the instantiating `@Bean` method. – Ilya Serbis May 24 '18 at 20:08
