Difference between @Bean and @Autowired

Question

Why can\'t I use @Autowired in this case?

@SpringBootApplication
public class Application {

    @Autowired
    BookingService bookingService;

         


        

Answer 1

@Bean is just for the metadata definition to create the bean(equivalent to tag). @Autowired is to inject the dependancy into a bean(equivalent to ref XML tag/attribute).
