how to do annotation configuration in spring
To configure annotation in Spring, you can follow these steps:
Add the
@Configuration
annotation to a class to indicate that it will be used for Java-based configuration.Use the
@ComponentScan
annotation to specify the base packages to scan for components such as@Component
,@Repository
,@Service
, or@Controller
.If necessary, use the
@Import
annotation to import additional configuration classes.Apply specific annotations such as
@Bean
to methods that will return bean instances.Optionally, use stereotype annotations like
@Component
,@Service
,@Repository
, or@Controller
to mark specific classes for auto-detection and automatic bean registration.Use other annotations like
@Value
,@Autowired
, and@Qualifier
to wire beans and inject properties.
These steps will help you configure annotation in Spring for your application.
