我刚开始使用Orika，我想将数据从我的应用程序中使用的业务实体（'PaymentPlan'）映射到我用于数据传输的POJO（'ShopifyRecurringApplicationCharge'）。
一切似乎都运行正常（甚至是字符串＆lt; - ＆gt;日期的自定义转换器），除了字段..
从'ShopifyRecurr ..'转换为'PaymentPlan'时，我希望String被解析并转换为'int'，但字段值只保持'0'。反过来说，'ShopifyRecurr ... ChargeInner.ID'只是保持为空。
编辑：我查看了Orika生成的映射器，发现shopifyID / id属性没有CODE，尽管我已经在Orika-Mapping中明确指定了它们。我还附上了下面生成的来源。
我犯了任何愚蠢的错误吗？

答案 0 :(得分：2)
我终于意识到问题不在于Orika，而是我对PaymentPlanMapper的实现以及enum-singleton的不合适的设计模式。
结果是
Orika的自动生成让我很难发现自己的错误，因为orika的大部分事情看起来都很好。
在调试自动生成的映射器（'Orika_ShopifyRecurringApplicationCharge_PaymentPlan_Mapper7011935565727 $ 0'）并找到属性'fromAutoMapping'为TRUE时，我才意识到出了什么问题。因此，对于类似的问题，查看生成的映射器源是有意义的。
为了为生成的映射器启用源代码和调试，我使用了“启用步骤调试”和“生成源和/或类文件”部分。在Orika Documentation。
该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");
我现在用..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。
