您也可以使用Orika，它还支持轻松编码的hetrogenous mapping。

您可以使用像Dozer这样的对象映射器。

Answer 3

Another alternative is MapStruct (disclaimer: I'm the original author of this project). MapStruct generates mapping code at compile-time which is thus fast and type-safe, ie you don't have any runtime dependencies and get feedback about incompatible mappings at build time, eg within your IDE.
