如何排除對象屬性

Question

我使用Orika mapper來映射兩個bean。 我想在映射時排除billingSummary.billableItems屬性。 我正在嘗試下面的選項，但它不起作用。

有幫助嗎？

public class Cart {
       private String id;
       private String name;
       private BillingSummary billingSummary;
       private String address;
       //with getter and setter methods
    }

   public class BillingSummary {
       private String billingItem;
       private String billingItemId;
       private BillableItems billableItems;
       ...
       // with getter setter methods
   }

   //FilteredCart is same as Cart.


 public class FilteredCart { 
        private String id;
        private String name;
        private BillingSummary billingSummary;
        private String address;
        //with getter and setter methods
    } 

@Component   
public class CartMapper extends ConfigurableMapper {
        @Override
        public void configure(MapperFactory mapperFactory) {
        mapperFactory.classMap(Cart.class,FilteredCart.class).exclude("billingSummary.billableItems").byDefault().register();
        }
}

Answer 1

您可以做的是向mapperFactory添加另一個映射，以便定義您希望如何將BillingSummary映射到自身。 這樣，從Cart到FilteredCart映射時，您可以配置為排除以映射billableItems 。

因此，您的CartMapper將如下所示：

@Component   
public class CartMapper extends ConfigurableMapper {

    @Override
    public void configure(MapperFactory mapperFactory) {
        mapperFactory.classMap(BillingSummary.class, BillingSummary.class).exclude("billableItems").byDefault().register();
        mapperFactory.classMap(Cart.class,FilteredCart.class).byDefault().register();
    }
}
