Why this program matters

  • Without mastering the automation of data transformations in Java, developers waste 35 to 50% of their time on repetitive, error-prone manual mappings.

  • Each mapping error generates an average of 2 to 5 production incidents per month, costing the company 8,000 € in debugging and downtime.

  • Without this expertise, 25% of backend projects exceed budgets by 20%, threatening scalability and the careers of software architects.

  • Every quarter without optimization exposes your team to cumulative losses of 25,000 € and relentless competition.

MapStruct training objectives

  • Understand the challenges of data mapping in modern Java applications
  • Install and configure MapStruct in a Maven or Gradle project
  • Create and customize mappers to efficiently convert entities and DTOs
  • Use advanced features: conditional mapping, expressions, after/before mapping
  • Integrate MapStruct with Spring, manage dependency injection in mappers
  • Test and debug automatic conversions to ensure data exchange reliability

MapStruct curriculum: 3 modules over 3 days

Module 1 : Fundamentals of Mapping and Introduction to MapStruct

Presentation of data transformation needs in Java architectures. Limitations of manual conversions. Getting started with MapStruct: installation, quick configuration with Maven/Gradle. Structure and principles of mapper interfaces. Demonstration: first mapping between entities and DTOs.

Module 2 : Custom and Advanced Mapping with MapStruct

Mapping complex properties: type conversions, collections, inheritances. Use of annotations @Mappings, @Mapping, @InheritInverseConfiguration, @MapperConfig. Application of custom conversions via expressions and utility methods. Lifecycle management with @BeforeMapping and @AfterMapping hooks.

Module 3 : Integration, Testing, and Performance of MapStruct

Integrate MapStruct into a Spring or Jakarta EE project: dependency injection, mapping in service layers. Optimize configuration for large data volumes. Best practices for testing mappers: JUnit, specific assertions, dependency mocks. Common issue resolution. Q&A and practical workshop on a real case.

How MapStruct skills are assessed

  • Validation quiz at the end of each day
  • Continuous evaluation through practical exercises and case studies
  • Final review on a concrete project

How the MapStruct course is taught

  • Interactive presentation (slides, live demos)
  • Step-by-step exercises (individual and group)
  • Case study of integration into a real application
  • Downloadable PDF course materials

Our method

How Learni guarantees the quality of your MapStruct training

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
