The Learni story
Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Why this program matters
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Program
Module 1Introduction to MapStruct: configuration and first mappers (Maven, annotations, code generation)
Discover MapStruct 2026 through quick installation with Maven in IntelliJ, configure the annotation processor to automatically generate mapping code, complete your first practical exercises on simple DTOs and entities, test bidirectional conversions with integrated validations, analyze the generated code to understand internal mechanisms, and produce a functional deliverable ready for an enterprise project, all in 7 hours of interactive and hands-on learning.
Module 2Advanced MapStruct Mappers: customization and expressions (Lombok, before/after, nested)
Dive into MapStruct 2026 customizations with Lombok to reduce boilerplate, implement before and after methods for complex business transformations, handle nested mappings and collections with conditional expressions, practice on real cases like converting hierarchical object lists, integrate qualifiers and views for maximum flexibility, debug code generation through guided exercises, and validate skills with a deployable custom mapper for teams, over 7 hours rich in practice.
Module 3MapStruct Integration: Spring Boot, tests and best practices (JPA, deployment, optimization)
Integrate MapStruct 2026 with Spring Boot and JPA for seamless repositories, configure mapper beans in a real application context, develop unit tests with JUnit and MockMvc to validate mappings, optimize performance on large data volumes with profiling, apply best practices such as dependency injection and error handling, build a complete microservice project with source deliverables and documentation, and conclude with a certifying review over 7 hours, ready for enterprise use.

Our method
Training quality, guaranteed at every step
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.
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.
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.
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.
