Dozer is a Java Bean to Java Bean mapping framework that recursively copies data between objects, supporting simple and complex type mapping, bi-directional and recursive mapping, and automatic type conversion via XML or code-based configuration. The project is no longer actively developed and its maintainers recommend migrating to alternatives like MapStruct or ModelMapper.
Use cases
- map java beans to dtos without writing boilerplate converters
- copy data between domain objects and external service objects in a layered architecture
- recursively map nested collections of objects
- convert between different types automatically during object mapping
- configure bi-directional object mapping via xml
When to choose
- maintaining an existing codebase that already uses Dozer
- you need runtime-configurable, reflection-based mapping without code generation
- you need flexible xml-based mapping configuration for legacy systems
When to avoid
- starting a new greenfield project - the maintainers explicitly discourage this
- you want compile-time type safety and performance - prefer MapStruct
- you want an actively maintained library with ongoing bug fixes
