Answer 1

I was facing the same issue and it got fixed by removing Constructors from my Model class. Adding sample snippet below:

Map serviceDefinitionMapper = new HashMap<>();
    A def;
    B serviceCharacter;

    @Autowired
    public Scan(Map serviceDefinitionMapper, A def,
            B serviceCharacter) {
        super();
        this.serviceDefinitionMapper = serviceDefinitionMapper;
        this.def = def;
        this.serviceCharacter = serviceCharacter;
    }

Please Note: Do not keep any Constructor/@AllArgsConstructor in your Model class unless it is very much needed to be decalred.
