What is the difference between @Component, @Repository and @Service in Spring?

Hi! I started learning Spring and trying to understand stereotype annotations. It seems like all three (@Component, @Repository, @Service) do the same thing — register a bean in the Spring context. But why are there three of them? I wrote a simple service for working with users. Here is my code: ```java @Component public class UserService { public void saveUser(User user) { System.out.println("User saved: " + user.getName()); } } @Repository public class UserRepository { public void saveToDatabase(User user) { // database work here } } @Service public class UserManager { public void processUser(User user) { // business logic } } ``` All three work, I can inject any of them using @Autowired. So what is the fundamental difference?
