I have a requirement where I have to modify the annotation
@Qualifier(CONSTANT + "ABC")
DataSource dataSource;
to
@DataSourceQualifier("ABC")
DataSource dataSource;
Here is my Annotation code:
@Retention(RetentionPolicy.RUNTIME)
@Target(value = {ElementType.FIELD})
public @interface DataSourceQualifier {
String value();
}
Is it even possible to do this? I have previously used annotation with AOP but I do not understand how to create this decorator annotation.
If there was no value
involved, then it would be possible assuming Qualifier
annotation is annotated with @Inherited
, then you could annotate your DataSourceQualifier
with the @Qualifier
, then all the places that you annotate with @DataSourceQualifier
for the purpose of annotation processing would act as if they had the @Qualifier
annotation.
However, if you want to do any passing of a your annotation's value into the metaannotation value, that's not possible.
