Mapping in Java Options
1 like1,211 views
This document discusses several object mapping libraries for Java, including Dozer, Orika, and JMapper. It provides information on their versions, last release dates, supported configurations, features, and performance characteristics to help determine the best option for mapping objects. Dozer is the most popular but less actively maintained, while Orika and JMapper generate bytecode for faster mapping and have more recent development.
Mapping in Java Options
- 1. Mapping options by Ania Pietras
- 2. Why to use mappers? - default settings -> less coding - ‘global’ settings for handling NULLS, empty String ect. - Simple conversions handling (lists, enums, different numeric types) ‘out of the box’ - Centralization of mapping configuration in application
- 3. Available options Source: http://stackoverflow.com/questions/1432764/any-tool-for-java-object-to-object-mapping/1432956 ● Transmorph ● EZMorph ● Commons-BeanUtils ● Commons-Lang ● Commons-Convert ● Morph ● Lorentz ● Dozer ● ModelMapper ● OTOM ● Smooks ● MapStruct ● Orika ● JMapper

- 6. Dozer ● Reflection based (==slowly) ● Mapping from map to Object ● Develop since 2006r. ● Most popular ● Not actively maintained (152 issues on GitHub) ● stackOverflow: 1519 result XML ANNOTATION JavaConfig
- 7. Orika - Generates bytecode during first mapping (first time is slow, then faster) - 27 open issues on GH - Last commit 2 months ago - stackOverflow: 211 results - Developed since 2012 JavaConfig
- 8. Jmapper - Generates bytecode during application startup - Last commit one month old - 5 open issues on GH - Dynamic converter declaration (code snippets, including xml) - Field mapping 1:n and n:1 - Support for flattening and encapsulation - StackOverflow: 19 results - Developed since 2013 @GlobalJMap ANNOTATIONS XML
