Inject and use Spring Boot services inside Quarkus App

[kannas99]

Hello, I'm trying to create a quarkus API for a spring boot application by calling it using maven parent.
The problem is that by trying to use its services, a null pointer exception appears.

I tried :

• Use the annotation @Autowired using spring dependencies. // not working
• Add the @ApplicationScoped annotation of jakarta in the parent class and @injected in the api class. // not working.

Is there a possible solution in this case ?

Thanks in advance.

Can you provide some example code that isn't working?
Also the pom.xml will be useful

@Autowired
ConsultantDao consultantDao;

public void onStart(@observes StartupEvent ev) {
List res = consultantDao.getSousTraitants();
}

Error

Unsatisfied dependency for type ...ConsultantDao and qualifiers [@Default]

Note : The same example working in the same api but in spring

[geoand]

What does ConsultantDao look like?

[kannas99]

An Interface with @component
@Mapper annotations.

[geoand]

What is @Mapper? And where is the implementation of the interface?
