You could use a object mapper like Dozer.

You can also use Orika it also support hetrogenous mapping with ease coding.

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, i.e. you don't have any runtime dependencies and get feedback about incompatible mappings at build time, e.g. within your IDE.
