@Value not working as expected in mapper abstract class

Question

So I have a mapstruct mapper in my app, which has source to destination pojo mappings. I perform some logic inside the @AfterMapping class using the value from the @Value like below. But it seems like the value is not being fetched and hence its set as null What am I missing here?

@Mapper
abstract class Student{

@Value("${spring.application.name}")
String appName;

abstract StudentModel convert(StudentDTO Studentdto);

@AfterMapping
void postConvert(@MappingTarget StudentModel studentmodel,StudentDTO studentDTO) {
studentmodel.setName(appName)

}

application.yml

spring:
   application:
       name: ABC

You can try and replace `@Mapper` with `@Mapper(componentModel = "spring")`, — GJohannes, Jul 13 '22 at 14:52

I have never used mapstruct, but spring injects values only into beans (like @Service, @Repository, @RestController or @Component). Your student class is not a bean, moreover it is an abstract class. Probably you need to pass appName from some service and use @Value there
