Spring Boot Jumpstart: Essentials

Build web APIs from scratch. Master Inversion of Control, type-safe architecture, and make your application cloud-ready with profiles and Actuator.

Expected Outcome

A deep understanding of how Spring Boot handles web requests, dependencies (DI), environment configurations, and cloud monitoring in production.

Target Audience

Java developers seeking a fast and in-depth introduction to Spring Boot to understand the framework's core and build scalable architecture from day one.

Prerequisites

Strong Java experience equivalent to 'Java Foundations: Fast-track' is required to quickly absorb the framework.

Curriculum & Highlights

REST Controllers & Routing
Inversion of Control (IoC)
Dependency Injection (DI)
@ConfigurationProperties
Spring Profiles (Dev/Prod)
Actuator & Health Indicators
Resolving @Qualifier Collisions
Enterprise Logging (SLF4J)

Challenges we address

"How does Inversion of Control work and how are interface collisions avoided?"

"How is a type-safe architecture built and data exposed via REST controllers?"

"How is the application made cloud-ready with profiles and custom health checks?"

Detailed Description
When Spring Boot's auto-configuration is allowed to remain a 'black box,' uncertainty often arises during debugging and further development. Building sustainable systems requires a fundamental insight into how the framework's core works, how the architecture is structured, and how the application is monitored in production. In this workshop, Spring Boot is demystified through Active Learning. The web layer is built via REST controllers and a professional layered architecture is established to fully understand Inversion of Control (IoC) and Dependency Injection. Finally, the application is taken all the way to production by implementing environment profiles and vital health checks, giving the team a solid foundation to make confident architectural decisions. The depths of the application context are explored by handling common pitfalls like Component Scan traps and interface collisions using @Qualifier. Furthermore, brittle, hardcoded strings are replaced with type-safe external configuration via @ConfigurationProperties. Professional SLF4J logging is configured, and Spring Profiles are used to seamlessly switch business logic between development and production environments without changing the Java code. Actlea's core philosophy is that Spring Boot's magic is its greatest asset, but only when it is transparent to the developer. As a finale, the architecture is connected to modern cloud environments using Spring Boot Actuator. By building custom Health Indicators for the business logic, it is demonstrated how cloud infrastructure can automatically monitor and restart failing systems. This workshop serves as the ultimate starting point for building robust backend systems ready for extreme scale.
Recommendation & Next Steps

With the basics and architecture in place, a deep dive into the web layer is recommended in the 'RESTful APIs with Spring Boot' workshop.

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.
