What Java Mapping Tools Automate Data Object Conversion?

Mapping Java Objects with Automated Tools

When converting data objects (DOs) to data transfer objects (DTOs), automation is often preferable to manual conversion. This article explores various tools available to automate this process.

Commons-BeanUtils

Commons-BeanUtils offers utility methods for converting scalar String values to objects and String arrays to arrays.

Commons-Lang

Commons-Lang's ArrayUtils provides operations for arrays, primitive arrays, and primitive wrapper arrays.

Spring Framework

Spring supports PropertyEditors, which can transform objects to and from Strings.

Dozer

Dozer recursively copies data between Java Beans of different complex types.

ModelMapper

ModelMapper uses a convention-based approach for object mapping, offering a flexible API for specific use cases.

MapStruct

MapStruct generates compile-time mapping code, resulting in fast, dependency-less, and type-safe mapping at runtime.

Orika

Orika utilizes byte code generation to create fast mappers with minimal overhead.

Selma

Selma generates mapping code at compile time for increased performance.
