通辽网站开发,浏览器游戏网址,网页链接怎么弄,汕头市澄海建设局门户网站这篇文章着眼于使用Orika将JAXB对象映射到业务域对象。 本月初#xff0c; 我使用基于反射的Dozer讨论 了相同的映射用例 。 在本文中#xff0c;我假设需要映射相同的示例类#xff0c;但是它们将使用Orika而不是Dozer进行映射 。 Dozer和Orika旨在解决相同类型的问题 我使用基于反射的Dozer讨论 了相同的映射用例 。 在本文中我假设需要映射相同的示例类但是它们将使用Orika而不是Dozer进行映射 。 Dozer和Orika旨在解决相同类型的问题两个“数据”对象的自动映射这些对象不共享公共继承但表示相同的数据字段。 推土机使用反射来完成此操作而Orika使用反射和字节码操作来完成此操作。 Orika的口号是“更简单更轻便更快的Java bean映射”。 Orika拥有版本2的Apache许可证可以从https://github.com/orika-mapper/orika/archive/master.zip 源或http://search.maven.org/#search下载。 | ga | 1 | orika 二进制。 Orika对Javassist 用于字节码操作 SLF4J和paranamer 用于在运行时访问方法/构造函数参数名称具有依赖性 。 这三个依赖项中的两个JavaAssist和paranamer而不是SLF4J捆绑在orika-core-1.4.4-deps-included.jar 。 如果依赖项已经可用则可以使用更薄的orika-core-1.4.4.jar 。 就像这些JAR的名称所暗示的那样在本文中我使用Orika 1.4.4作为示例。 在我的《 推土机将JAXB对象映射到业务/域对象》一文中 我讨论了通常不希望将JAXB生成的类的实例用作业务或域对象的原因。 然后我展示了JAXB生成的类和自定义数据类之间的“传统”映射方式以便可以在业务域数据对象中的整个应用程序中传递数据。 在本文中我将使用相同的方法但是使用Orika进行映射而不是进行自定义映射或使用Dozer进行映射。 为了方便起见我在此处列出了JAXB生成的类com.blogspot.marxsoftware.AddressType和com.blogspot.marxsoftware.PersonType的成本清单以及重命名的自定义数据类dustin.examples.orikademo.Address和dustin.examples.orikademo.Person 。 JAXB生成的AddressType.java //

} 与Dozer的情况一样两个类之间的映射是双向的因此只需要进行一次映射并将应用于从一个对象到另一个对象的复制。 结论 像推土机一样Orika提供的可定制性和灵活性比本文中演示的要好得多。 但是对于相对简单的映射在使用JAXB生成的对象的应用程序中很常见Orika非常易于使用。 《 Orika用户指南》是了解Orika的一个很好的资源。 参考 Orika来自JCG合作伙伴 Dustin Marx在实际事件启发博客上将JAXB对象映射到业务/域对象 。 翻译自: https://www.javacodegeeks.com/2013/12/orika-mapping-jaxb-objects-to-businessdomain-objects.html
