MapStruct vs FF4J: What are the differences?

Developers describe MapStruct as "A Java code generator for creating fast and type-safe bean mappings at compile time". It 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. On the other hand, FF4J is detailed as "Feature Flags for Java made easy". It is an implementation of Feature Toggle pattern : Enable and disable features or your applications at runtime thanks to dedicated web console, REST API, JMX or even CLI. It handle also properties and provide generic interfaces.

MapStruct belongs to "Java Tools" category of the tech stack, while FF4J can be primarily classified under "Feature Flags Management".

Some of the features offered by MapStruct are:

Mapping (immutable) objects using builders
Enhanced and more flexible update method (@MappingTarget) handling
Constructor injection for Annotation Based component models

On the other hand, FF4J provides the following key features:

Feature Toggle
Role-based Toggling
Strategy-based Toggling

MapStruct is an open source tool with 2.82K GitHub stars and 430 GitHub forks. Here's a link to MapStruct's open source repository on GitHub.

What are some alternatives to MapStruct, FF4J?

Quarkus

It tailors your application for GraalVM and HotSpot. Amazingly fast boot time, incredibly low RSS memory (not just heap size!) offering near instant scale up and high density memory utilization in container orchestration platforms like Kubernetes. We use a technique we call compile time boot.

MyBatis

It is a first class persistence framework with support for custom SQL, stored procedures and advanced mappings. It eliminates almost all of the JDBC code and manual setting of parameters and retrieval of results. It can use simple XML or Annotations for configuration and map primitives, Map interfaces and Java POJOs (Plain Old Java Objects) to database records.

ConfigCat

Cross-platform feature flag service for Teams. It is a hosted or on-premise service with a web app for feature management, and SDKs for all major programming languages and technologies.

Unleash Hosted

It is a simple feature management system. It gives you great overview of all feature toggles across all your applications. You decide who is exposed to which feature.

guava

The Guava project contains several of Google's core libraries that we rely on in our Java-based projects: collections, caching, primitives support, concurrency libraries, common annotations, string processing, I/O, and so forth.

LaunchDarkly

Serving over 200 billion feature flags daily to help software teams build better software, faster. LaunchDarkly helps eliminate risk for developers and operations teams from the software development cycle.

Airship

Airship is a modern product flagging framework that gives the right people total control over what your customers see & experience - without deploying code.

Thymeleaf

It is a modern server-side Java template engine for both web and standalone environments. It is aimed at creating elegant web code while adding powerful features and retaining prototyping abilities.
