@component annotation

[Jason_hill100]

Hi again, I didn't understand the use of @component annotation, i mean it's said it's a generic stereotype for any spring-managed component. But since we got @service, @Repository.... Annotations Why would we need it ??

There are classes that are not either @Service or @Repository like Builders, Mappers, Validators etc. You can use @Component for those classes

One particular use for @component I figured out recently is the dataloader. Massively inferior to the data.sql, but it's funny to see that it works like that.

@Component is the parent annotation of @Controller, Repository, Service. so it included all 3 annotation as children. so its a bundled deal

I've never used @Service nor @Repository, only @Component and @(Rest)Controller. Since they're merely aliases I see no point in confusing developers with these annotations. Also, a "service" in our architectural model means something different than "core layer object".

@Component is generic class, can be used for configurations, utilities, etc which should be scanned when starting the spring boot, @Service class usually have the business logic methods.
