If we have @Service, @Controller, @Configuration, and @Repository why do we need @Component? Can we replace them with @Component?

Question

Accepted Answer

The @Component annotation is a generic stereotype annotation that can be used in place of other annotations.

The @Component annotation is a general-purpose annotation that can be used in place of @Service, @Controller, @Configuration, and @Repository annotations.
However, using more specific annotations can help in better understanding the role of the annotated class.
For example, using @Service annotation on a class that provides a service makes it easier to understand the purpose of the class.
Similarly, using @Controller annotation on a class that handles web requests makes it easier to understand the role of the class.
Using @Component annotation on a class that does not fit into any of the other categories is a good option.
It is also possible to create custom stereotype annotations that can be used in place of @Component annotation.
Replacing specific annotations with @Component annotation can make the code more concise and easier to read.
However, it is important to use annotations that accurately describe the role of the annotated class.
