Qualifier annotation in Spring Boot does not work for the class that extends another one

[Bronislav Bronek]

I have this hierarchy:

@Primary
 class A implements B ....

 class X implements B ...

 @Component("needThis")
 class Y extends X

In the line below class A is injected not Y ( I need Y ):

@Qualifier("needThis")
private final B b;

Could you please tell me how to do in Spring Boot to inject class Y ?
The problem probably is that class A has @Primary annotation but does @Qualifier not have a priority ?

@Qualifier has indeed higher priority than @Primary. Works as expected for me with sample program according to your structure. Do you have all those classes in scope of Spring's component scan?

// Edit: You should have class A in scope of component scan, otherwise bean would not be found, but check if class Y is in scope of component scan.

Hi, Bronishlav,
Please try to add @Autowired to see if it can autowire your Y bean

@Autowired
@Qualifier("needThis")
private final B b;
