@Autowired

@Autowired

• @Autowired is used for automatic dependency injection in Spring. It can be applied to constructors, methods, and fields

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

• Use @Autowired with @Qualifier can specify which implementation to inject

• Use @Primary with @Component can set that implementation as default bean
