JMapper Tutorial

Description

JMapper object-mapping framework is similar to MapStruct configuration mechanism that should be provided beforehand. Several configuration variants cab be supported:

• XML-based

• annotation-based

• programmatic configuration via Java API

Uses the bytecode generation mechanism based on Javassist library to provide end-to-end mappings.

Features

• relational mapping of several classes to one class (many to one) and vice versa (one to many)

• configurations inheritance

Pros & Cons

Pros

• high performance due to bytecode generation mechanism (Javassist library)

• easy-to-use feature mappings

Cons

• hard to debug and validate object mappings correctness
