Spring & Spring Boot Annotations Series - #3 - @Qualifier Annotation

Hi, welcome to Spring & Spring Boot Annotations Series. In this video, we will learn how to use @Qualifier annotation to avoid confusion when we have two or more beans configured for the same type.

@Qualifier annotation is used in conjunction with Autowired to avoid confusion when we have two or more beans configured for the same type.

You did not discuss the most obvious point : What is the difference between using the interface and the qualifier (like you did) vs. using the implementing class itself in the constructor ? You simply dumped the abstraction, if I understand it right.

didn't using @qualifier defeats polymorphic design ? We code to interface so that we polymorphically resolve method definitions .
