Automapper for Java [closed]

Question

Is there Java equivalent of .Net's Automapper?

If you could tell us what Automapper does in .NET, then we Java-freaks could answer as well ;-) – Patrizia

Despite this question being closed, it contains a lot of great information! There are many other mappers not mentioned here. Please see this article for a great comparison of examples and performance (2018): baeldung.com/java-performance-mapping-frameworks – Cards

Answer 1

Checkout the Dozer project.

Dozer supports simple property mapping, complex type mapping, bi-directional mapping, implicit-explicit mapping, as well as recursive mapping.

It makes use of BeanUtils and extends on it.

Future readers, keep in mind that Dozer is one of the slowest mappers available. This may or may not matter for you depending on your usage :) – Cards

Answer 2

Check out my ModelMapper. It was inspired by AutoMapper, but adds a few new things such as intelligent mapping.

ModelMapper is an intelligent object mapping framework that eliminates the need to manually map objects to each other. It uses a convention-based approach to map objects while providing a simple refactoring safe API for handling specific mapping scenarios.

Be aware of this issue if writting custom mappings: github.com/jhalterman/modelmapper/issues/87 I just ran in to this one at it's thrown a bit of a spanner in the works! – Reticulum

ModelMapper appears really powerful. As someone coming from C#/AutoMapper background, I would recommend checking this out. – Unrig

Answer 3

You should check the open source project Beanutils from Apache Commons.
