Rhuan Karlus :
I've already read about each Spring annotation in What's the difference between @Component, @Repository & @Service annotations in Spring?
I know that @Component and @Service do almost the same inside the Spring Framework. The difference it's bounded to it's usage, so I just use @Service into the service layer where I access my repositories.
I want to know what's the better way to choose @Component instead of @Service. Note that I'm using @Component now for a factory I've created, because the factory don't need to deal with repositories.
Makoto :
Keep in mind that these are Spring stereotypes, and should be applied as stereotypes or assumptions around one's code are usually applied.
- If your component is a generic component, not really living at the service layer, or is accessible but could hold state, then use
@Component. - If your component is a specific service, living at the service layer, or is accessible and does not inherently hold state, use
@Service.
Spring sees both of these ultimately as @Components.
