ModelMapper issue with mapping basic POJOS - spring

Question

I have 2 basic POJOs that i use to build a json object :
public class ProductCreateRequestModel {
private String name;
private double price;
private int qty;
private String imgPath;
private CategoryRequestCreateProductModel category;
}
public class CategoryRequestCreateProductModel {
private String name;
private String categoryKeyId;
}
Basically it allow me to use a simple json like this one :
{
"name": "Pizza,
"price": 344.0,
"qty": 15,
"imgPath": "new/pathImage",
"category": {
"categoryKeyId": "23ume70Fu6yqyGUWfQkW110P4ko3gZ",
"name": "Starter"
}
}
I want to send this JSON and persist datas and i expect an object in return that i build with this POJO:
public class ProductRest {
private String productKeyId;
private String name;
private double price;
private int qty;
private String imgPath;
private CategoryRest category;
}
In my controller i just have to call a method which use PostMapping
#PostMapping(
consumes = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE },
produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE }
)
public ProductRest createProduct(#RequestBody ProductCreateRequestModel productCreateRequestModel) throws Exception {
ProductRest returnValue = new ProductRest();
if(productCreateRequestModel.getName().isEmpty() || productCreateRequestModel.getPrice() <= 0)
throw new ApplicationServiceException(ErrorMessages.MISSING_REQUIRED_FIELDS.getErrorMessage());
ModelMapper modelMapper = new ModelMapper();
ProductDto productDto = modelMapper.map(productCreateRequestModel, ProductDto.class);
ProductDto createdProduct = productService.createProduct(productDto);
returnValue = modelMapper.map(createdProduct, ProductRest.class);
return returnValue;
}
My service layer is actually doing nothing special :
#Override
public ProductDto createProduct(ProductDto productDto) {
return productDto;
}
My DTO layer contains the following fields :
#Getter #Setter
public class ProductDto implements Serializable {
// ommit this member and do not generate getter / setter
#Getter(AccessLevel.NONE)
#Setter(AccessLevel.NONE)
private static final long serialVersionUID = 1L;
private Long id;
private String productKeyId;
private String name;
private double price;
private int availableQty;
private String imgPath;
private CategoryDto category = new CategoryDto();
}
#Getter #Setter
public class CategoryDto implements Serializable {
#Getter(AccessLevel.NONE)
#Setter(AccessLevel.NONE)
private static final long serialVersionUID = 1L;
private long id;
private String categoryKeyId;
private String name;
private CategoryDto parentCategory;
private List<CategoryDto> subCategories;
private String parentCategoryKeyId;
private Long parentCategoryId;
}
While trying to run this basic code I obtain an error message :
java.lang.NumberFormatException: For input string: "23ume70Fu6yqyGUWfQkW110P4ko3gZ"
