Orika

Question

我刚刚开始使用 Orika，我想将数据从我的应用程序 ('PaymentPlan') 中使用的业务实体映射到我用于数据传输的 POJO ('ShopifyRecurringApplicationCharge' ).

一切似乎都工作正常（甚至是 String<->Date 的自定义转换器），除了字段..

PaymentPlan.shopifyID（整数）
ShopifyRecurringApplicationChargeInner.id（字符串）

从 'ShopifyRecurr..' 转换为 'PaymentPlan' 时，我希望字符串得到解析并转换为 'int'，但字段值保持为“0”。相反，'ShopifyRecurr...ChargeInner.ID' 只是保持为空。

编辑： 我查看了 Orika 生成的映射器，发现属性 shopifyID/id 没有代码，尽管我已经在Orika-映射。我还在下面附上了生成的源代码。

我是不是犯了什么愚蠢的错误？

Answer 1

我终于意识到问题不在Orika，而是我的PaymentPlanMapper实现和enum-singleton设计模式不合适。

结果是

PaymentPlannerMapper 从未初始化
我的自定义映射从未在 MapperFactory 注册
当 facade.map(..) 被调用

Orika 的自动生成让我很难发现我自己的错误，因为 orika 所做的大部分事情看起来都不错。

我只是在调试自动生成的映射器 ('Orika_ShopifyRecurringApplicationCharge_PaymentPlan_Mapper7011935565727[=41=]') 并发现属性 'fromAutoMapping' 为 TRUE 时才意识到哪里出了问题。因此，对于类似的问题，查看生成的映射器源是有意义的。

调试生成的映射器

为了启用生成的映射器的源代码和调试，我使用了 Orika Documentation 中的 'Enable step-debugging' 和 'Generate Source and/or Class Files.' 部分。

文档基本上转换为在应用程序启动时调用以下代码：

System.setProperty(OrikaSystemProperties.COMPILER_STRATEGY,EclipseJdtCompilerStrategy.class.getName());
System.setProperty(OrikaSystemProperties.WRITE_SOURCE_FILES,"true");
System.setProperty(OrikaSystemProperties.WRITE_CLASS_FILES,"true");

正确的映射器

我现在已经用 ..

替换了我的映射器

@Component
public class PaymentPlanMapper {

    private PaymentPlanMapper()  {
        ShopifyBaseMapper.factory.classMap(PaymentPlan.class, ShopifyRecurringApplicationCharge.class)
        .field("shopifyID","id")
        .byDefault()
        .register();
    }

}

.. 使用 Spring 而不是 Enum-Singleton 模式。

Orika - 不生成字段映射；只有 byDefault 有效

Orika - Does not generate field-mapping; only byDefault works
