Mastering Spring Data & Persistence

Learn to handle data effectively with Spring Data JPA. Master Repositories, entity mapping, and transactions in Spring Boot 3.

Expected Outcome

The ability to build a stable data layer with correct entity mappings and functioning transaction management.

Target Audience

Backend developers wanting to practically implement and structure the data layer with Spring Data JPA.

Prerequisites

Experience with Spring Boot equivalent to 'Spring Boot Jumpstart: Essentials' is required to dive into persistence.

Curriculum & Highlights

Spring Data JPA Repositories
Entity Mapping (@Entity)
Transactional Logic (@Transactional)
Derived Query Methods
Relationships (@OneToMany / @ManyToOne)
Sorting & Pagination
JPQL & Custom Queries
Jakarta Persistence (JPA) Essentials

Challenges we address

"How do I map my classes to entities and create relationships smoothly?"

"How do I use Spring Data Repositories to quickly fetch and save data?"

"How does @Transactional work and how do I ensure my data operations are safe?"

Detailed Description
The data layer is the backbone of any application, but it's also where many complex errors can occur if you don't master the basics. Working with Spring Data JPA in 2026 is about letting the framework handle the heavy lifting while maintaining control over how information is saved and retrieved. In this workshop, we focus on practical work through Active Learning, building a data layer step by step. We cover how to map classes to database tables, create relationships, and use the power of the Spring Data Repository pattern. The goal is to give the team confidence in structuring their persistence logic in a way that is both readable and easy to maintain. We explore the management of entities by looking at how various annotations affect the database structure and how to create smooth relationships between them. We implement functional Repositories and learn to write custom queries when the built-in methods aren't enough. By using @Transactional, we ensure our operations are executed safely and data integrity is preserved throughout the application flow according to modern Jakarta Persistence standards. Actlea's core philosophy is that a well-structured data layer saves an enormous amount of time and frustration in the long run. Experience shows that once you understand how Spring Data JPA maps code to data, development speed increases significantly. This training provides the team with the foundation needed to build robust Spring Boot applications where data management is both predictable and stable.
Recommendation & Next Steps

Once you know how to handle data in the database, the next natural step is exposing it professionally in 'RESTful APIs with Spring Boot'.

Expertise through Active Learning

Java and the Spring Framework have been my core focus for over 20 years. Today, my mission is primarily to help organizations step into the future by integrating intelligent agents and AI-driven features into modern Java systems.

Actlea stands for Active Learning – the philosophy that programming is best learned by writing code, not by watching slides. My workshops focus on intensive, hands-on exercises designed to solve real-world problems.

I deliver proven training concepts globally across all timezones. While I specialize in remote delivery, I love to travel for onsite workshops. My modules are ready for immediate impact but can be tailored to your team's specific requirements.
