另一个是Orika - https://github.com/orika-mapper/orika

Orika is a Java Bean mapping framework that recursively copies (among other capabilities) data from one object to another. It can be very useful when developing multi-layered applications. Orika focuses on automating as much as possible, while providing customization through configuration and extension where needed. Orika enables the developer to : Map complex and deeply structured objects "Flatten" or "Expand" objects by mapping nested properties to top-level properties, and vice versa Create mappers on-the-fly, and apply customizations to control some or all of the mapping Create converters for complete control over the mapping of a specific set of objects anywhere in the object graph--by type, or even by specific property name Handle proxies or enhanced objects (like those of Hibernate, or the various mock frameworks) Apply bi-directional mapping with one configuration Map to instances of an appropriate concrete class for a target abstract class or interface Handle reverse mappings Handle complex conventions beyond JavaBean specs. Orika uses byte code generation to create fast mappers with minimal overhead.

我建议您试试JMapper框架。

它是一个Java bean到Java bean的映射器，允许您使用注释和/或XML动态地执行数据传递。

使用JMapper你可以:

创建并充实目标对象 对映射应用特定的逻辑 自动管理XML文件 实现1到N和N到1的关系 实现显式转换 应用继承的配置

还有一个Java映射引擎/框架Nomin: http://nomin.sourceforge.net。

你可以试试Dozer。

Dozer是一个Java Bean到Java Bean的程序 递归复制数据的映射器 从一个物体到另一个物体。通常情况下, 这些Java bean将是不同的 复杂类型。 Dozer支持简单属性 映射，复杂类型映射， 双向映射, 隐式-显式映射，以及 递归的映射。这包括 映射集合属性 还需要在元素处进行映射 的水平。

我很高兴添加Moo作为一个选项，尽管很明显我对它有偏见: http://geoffreywiseman.github.com/Moo/

它在简单的情况下很容易使用，在更复杂的情况下也很有能力，尽管我仍然可以想象在一些方面对它进行进一步的改进，以解决更复杂的问题。
