• Bean Mapping

  • dOOv - Provides fluent API for typesafe domain model validation and mapping. It uses annotations, code generation and a type safe DSL to make bean validation and mapping fast and easy.
  • JMapper - Uses byte code manipulation for lightning-fast mapping. Supports annotations and API or XML configuration.
  • MapStruct - Code generator that simplifies mappings between different bean types, based on a convention-over-configuration approach.
  • ModelMapper - Intelligent object mapping library that automatically maps objects to each other.
  • Orika - JavaBean-mapping framework that recursively copies (among other capabilities) data from one object to another.
  • reMap - Lambda and method handle-based mapping which requires code and not annotations if objects have different names.
  • Selma - Annotation processor-based bean mapper.
