I get an error when using the save(update) Function while adding with is working properly.
1.ProductService:
@Override
public ProductDTO save(ProductDTO product) {
ProductEntity entity= null;
if(product.getId()!=null)
{
ProductEntity oldProduct= productrepository.findById(product.getId()).get();
entity=converter.toEntity(product, oldProduct);
}else {
entity= converter.modelMapper().map(product, ProductEntity.class);
}
entity.setCategory(categoryRepository.findById(product.getCategoryId()).get());
entity.setOrigins(toList(originRepository.findById(product.getOriginId())));
entity.setMaterials(toList(materialRepository.findById(product.getMaterialId())));
entity.setType(typeRepository.findById(product.getTypeId()).get());
productrepository.save(entity);
return converter.modelMapper().map(entity, ProductDTO.class);
}
- add product & update:
@PostMapping(value="/product")
public ProductDTO addProduct(@ModelAttribute ProductDTO model)
{
return iProductService.save(model);
}
@PutMapping(value="/product")
public ProductDTO editProduct(@ModelAttribute ProductDTO model)
{
return iProductService.save(model);
}
- When I add the product it works properly, but when I update the product it throws an error:
