How do I use @Autowired in Spring?

How do I use @Autowired in Spring?

You can use @Autowired to automatically inject dependencies in your Spring beans. Just annotate the field, constructor, or setter method.

Can you show me an example of using @Autowired?

Sure! Here's a simple example:

@Component
public class MyService {
    @Autowired
    private MyRepository myRepository;
}

What if I want to use it with a constructor?

You can use @Autowired on the constructor like this:

@Component
public class MyService {
    private final MyRepository myRepository;

    @Autowired
    public MyService(MyRepository myRepository) {
        this.myRepository = myRepository;
    }
}

Are there any drawbacks to using @Autowired?

Yes, one drawback is that it can make your code less explicit and harder to test. Consider using constructor injection for better clarity.
