Hi JWells,

Thanks your reply very much!

I want to ask whether the above injection way is the same as the
following(field injection):

@Inject
TemplateRepository templateRepository;
        
@Inject
Domain domain;
        
@Inject
ServerContext environment;

public LocalServerPoolFactory() {}

Thanks
