"How do I ensure code quality through unit and integration tests for the entire application?"

Detailed Description
The Spring Boot ecosystem is vast, and it's easy to get lost among thousands of modules. A true expert needs to understand how the core interacts with data layers, user interfaces, and modern AI services to build reliable systems. This comprehensive five-day course is Actlea's flagship, providing the team with a total walkthrough of the framework's core components through intensive Active Learning. We move methodically from fundamental building blocks like beans, Dependency Injection, and auto-configuration to building both modern REST services and server-side rendered web applications. The course is flexibly designed and can be compressed to 3–4 days upon request by focusing on the team's specific priorities. The goal is to create a cohesive pedagogical journey that prepares participants to take full architectural responsibility in professional Spring Boot projects immediately after training. During the week, we master Spring MVC and Thymeleaf to create dynamic interfaces with secure form handling, while diving deep into Spring Data JPA for effective database integration. We implement extensive unit and integration tests with JUnit 5 to ensure system quality and introduce Spring Security for robust application protection. Additionally, we provide insight into how Spring AI can be leveraged to integrate intelligent language models, which together with profile and external configuration management, prepares the team for modern environments in 2026. Actlea's core philosophy is that true expertise requires an understanding of the entire chain; from the individual bean to the complete interface. Experience shows that when a team works practically with all parts of the framework during a cohesive week, both technical quality and delivery capacity increase significantly. This training serves as the definitive foundation that transforms a team's Java knowledge into complete and modern expertise within the Spring Boot ecosystem.

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.
