Thymeleaf vs MapStruct: What are the differences?
What is Thymeleaf? A template engine for Java. 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.
What is MapStruct? 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.
Thymeleaf and MapStruct can be categorized as "Java" tools.
MapStruct is an open source tool with 2K GitHub stars and 330 GitHub forks. Here's a link to MapStruct's open source repository on GitHub.
