How can I create a new annotation?

Question

How can I create a new annotation based on a Spring @Service annotation or @Component ?

I want just to change the name for a more semantic use: for example change the name to @TransactionelService .

Answer 1

You can create your own annotation (eg @MyComponent ) annotated with the corresponding spring annotation. For example:

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Component
public @interface MyComponent {
}

Answer 2

Meta-annotations:

Annotations which can be used to annotate other annotations.

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Service
@Transactional(timeout = 60)
public @interface MyTranscationalService{
}

--this recognizes the above code and scans the below code also

and we can use MyTranscationalService as annotation for other classes

@MyTranscationalService
public class TransferImpl implements TransferService{
}
