Why this program matters

  • Without expert mastery of JPA, Java applications suffer N+1 queries costing 50% more CPU time, triggering latencies that cut e-commerce conversions by 25% according to Gartner.

  • Memory leaks from poorly managed lazy loading trigger 30% of critical production incidents, costing companies an average of 150k€ per year.

  • Untrained teams lose 40% productivity on database migrations, risking obsolescence and turnover of senior devs.

  • In 2024, 68% of Java job postings require advanced JPA, widening the competitive gap against agile rivals.

JPA training objectives

  • Master advanced JPA mappings for scalable professional entities
  • Develop optimized queries with JPQL and Criteria API in enterprise settings
  • Implement caching and lazy loading to boost application performance
  • Design distributed transactions and robust error handling
  • Integrate JPA with Spring Data for production-ready and efficient repositories
  • Optimize persistence in microservices and cloud-native contexts

JPA curriculum: 2 modules over 2 days

Module 1 : JPA Modeling: Advanced Entities and Complex Relationships (Hibernate, Annotations, Mappings)

Dive into creating sophisticated JPA entities with inheritance, bidirectional relationships, and embeddings. Use @EmbeddedId and @ElementCollection annotations to model real-world business cases. Perform practical exercises on an ongoing e-commerce project. Test mappings with in-memory H2 and PostgreSQL. Analyze impacts on DDL schema generation. Produce an optimized production-ready data model with Bean Validation constraints.

Module 2 : JPA Optimization: Performance and Advanced Transactions (JPQL, Criteria, Spring Data)

Explore native JPQL queries and Criteria API for optimized fetches and dynamic projections. Implement second-level caching with Ehcache or Redis. Manage XA transactions and propagation in microservices. Integrate Spring Data JPA for custom repositories and advanced pagination. Apply exercises to real bottlenecks like N+1 queries. Measure performance gains with JMH and VisualVM. Deploy a final deliverable with integrated monitoring for professional-grade persistence.

How JPA skills are assessed

  • Expert multiple-choice quiz on JPA mappings and optimizations
  • Code review evaluation of the ongoing project
  • Technical presentation of the performance optimizations implemented

How the JPA course is taught

  • Sessions led by a practicing Java expert trainer
  • Practical exercises based on real enterprise cases
  • Evolving ongoing project spanning 2 days
  • Detailed course materials and open-source resources

JPA training: access and practical arrangements

The Training JPA - Optimizing Data Persistence in Java program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training JPA - Optimizing Data Persistence in Java program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Training JPA - Optimizing Data Persistence in Java program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Our method

How Learni guarantees the quality of your JPA 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

JPA: frequently asked questions

Which tools are used in JPA training?+
Hands-on work runs on hibernate, annotations, mappings, JPQL, criteria and spring Data. Those tools come from the JPA program itself, delivered on site over 2 days, so participants practise on the stack they will use at work.
What can participants do after JPA training?+
They can master advanced JPA mappings for scalable professional entities, develop optimized queries with JPQL and Criteria API in enterprise settings and implement caching and lazy loading to boost application performance. Those are the stated objectives of the JPA program at Expert level, checked by the end-of-session assessment.
What does the JPA program cover, day by day?+
Day 1: JPA Modeling: Advanced Entities and Complex Relationships (Hibernate, Annotations, Mappings). Day 2: JPA Optimization: Performance and Advanced Transactions (JPQL, Criteria, Spring Data). The JPA program runs over 2 days, delivered on site.
How is JPA training assessed?+
Assessment relies on expert multiple-choice quiz on JPA mappings and optimizations, code review evaluation of the ongoing project and technical presentation of the performance optimizations implemented. Learni issues a completion certificate together with the individual assessment report at the end of the JPA program, which an L&D team can file as evidence.
How much does JPA training cost per participant?+
JPA training costs $2,310 per participant. For an in-company team, the flat rate starts at $4,190 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 JPA training take?+
2 days, 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 JPA 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 JPA training?+
Advanced proficiency in Java 8+, complex SQL, basic Hibernate, and Spring Boot.
Is a certificate issued after JPA 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.
