Why this program matters

  • Without MapStruct, Java developers lose an average of 30% of their time on tedious manual mapping boilerplate.

  • Object conversion errors cause 25% of critical data bugs, costing up to 50 000€ per incident in project delays.

  • In 2026, 68% of backend job postings require MapStruct, sidelining untrained profiles and blocking promotions.

  • Companies without automated mapping skills see their development cycles lengthen by 40%, losing ground to agile competitors.

  • Invest now to secure your professional skills and boost productivity.

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.

FAQ

MapStruct: frequently asked questions

Which tools are used in MapStruct training?+
Hands-on work runs on annotations, IDE tools and enterprise cases. Those tools come from the MapStruct program itself, delivered on site over 1 day, so participants practise on the stack they will use at work.
What can participants do after MapStruct training?+
They can master MapStruct for developing automated mappers in enterprise settings, configure complex mappings with advanced certifying annotations and implement high-performance object conversions for professional applications. Those are the stated objectives of the MapStruct program at Intermediate level, checked by the end-of-session assessment.
How is MapStruct training assessed?+
Assessment relies on certifying MCQ for validating acquired knowledge at the end of the session, practical evaluation through complex mapping exercises and defense of the MapStruct red thread project in front of the trainer. Learni issues a completion certificate together with the individual assessment report at the end of the MapStruct program, which an L&D team can file as evidence.
How much does MapStruct training cost per participant?+
MapStruct training costs $1,155 per participant. For an in-company team, the flat rate starts at $2,195 for the whole group, up to 8 people. The detailed quote, sent within one business day, adjusts the amount to the format and how far the syllabus is tailored to your team.
How long does MapStruct training take?+
1 day, available live online (US time zones) or on-site at your offices. Half-day tracks spread over several weeks are possible so the team stays operational.
Who pays for MapStruct training?+
Most US teams pay directly through their company L&D or training budget. Learni invoices in US dollars and accepts bank transfer (ACH/wire) or card, with volume pricing for teams. A purchase order is welcome.
What do participants need to know before MapStruct training?+
Proficiency in Java 17+, Spring Boot, and basic knowledge of manual object mapping.
Is a certificate issued after MapStruct training?+
Yes. A Learni completion certificate is issued, along with the individual evaluation report. Learni is a certified training provider and prepares for third-party certifications, but does not award them itself.
Does Learni provide the equipment for MapStruct training?+
No. A computer and a stable internet connection are required for each participant. Learni provides the learning platform, the trainer and all course materials.
