Answer 1

Yes, you can go with @Qualifier annotation. As you have 3 classes which implement same interface, name those classes with different names and use @Qualifier annotation.

Spring documentation says : autowiring by type may lead to multiple candidates, it is often necessary to have more control over the selection process. One way to accomplish this is with Spring's @Qualifier annotation.
