Java: Simplify Object Mappings in Java with MapStruct

Hi All ,

Today , We will look in to the details of Simplifying Object Mappings in Java with MapStruct.

What is MapStruct ?

MapStruct is a code generator that greatly simplifies the implementation of mappings between Java bean types based on a convention over configuration approach.

The generated mapping code uses plain method invocations and thus is fast, type-safe and easy to understand.

MapStruct is a Java annotation processor for the generation of type-safe bean mapping classes. It allows developers to define mappings between Java classes using simple and intuitive annotations, reducing the amount of boilerplate code that needs to be written.It is an open-source project and is actively maintained by a team of developers.

Why we Need MapStruct?
Multi-layered applications often require to map between different object models (e.g. entities and DTOs). Writing such mapping code is a tedious and error-prone task. MapStruct aims at simplifying this work by automating it as much as possible.

In contrast to other mapping frameworks MapStruct generates bean mappings at compile-time which ensures a high performance, allows for fast developer feedback and thorough error…
