You asked for it. It’s finally happening!
I'm Mosh from Programming with Mosh, and after a long wait the Spring Boot course you asked for is finally ready. Spring Boot is the go-to framework for building modern Java applications, and learning it is one of the best investments you can make in your career. In this announcement I’ll walk you through what the course covers, why it’s worth your time, and how to prepare so you get the most out of it.
Why learn Spring Boot?
Spring Boot simplifies building production-ready Java applications by handling configuration, dependency management, and runtime concerns so you can focus on writing business logic. Companies actively hire Spring Boot developers, and mastering it opens doors to backend and full-stack roles.
According to Glassdoor, Spring Boot developers earn between $160,000 and $300,000 per year.
Course overview — a clear, structured, no-nonsense approach
This is a two-part series designed to teach Spring Boot the right way. The first part focuses on two of the most fundamental aspects:
- Dependency Injection (DI) — the backbone of Spring’s programming model
- Database integration with Spring Data JPA — how to persist data cleanly and efficiently
But we don’t just cover the basics. The course goes deep into concepts most other courses gloss over or skip entirely. Every concept is paired with real-world exercises so you can apply what you learn immediately.
What you’ll learn in Part 1
Dependency Injection — beyond the basics
- Core DI concepts: inversion of control, beans, and application contexts
- Bean scopes and lifecycle management
- Autowiring strategies and constructor vs. field injection
- Profiles, configuration properties, and environment-specific setup
- Practical patterns for building testable, maintainable services
Spring Data JPA — building robust data layers
- Entities, relationships (one-to-many, many-to-many), and mapping strategies
- Repository patterns and query creation (method names, @Query, and native queries)
- Transactions, optimistic/pessimistic locking, and consistency
- Pagination, sorting, and performance considerations
- Testing your data layer and integrating with real-world databases
Why this course is different
I designed this course to be clear, structured, and practical. That means:
- Deep dives on concepts often skipped elsewhere — not just surface-level tutorials
- Hands-on, real-world exercises that force you to apply and reason about concepts
- A non-nonsense teaching style that emphasizes how things work and why decisions matter
Who this course is for and prerequisites
This course is ideal for Java developers who want to move from libraries and frameworks to building production-grade services with Spring Boot. You should be comfortable with:
- Core Java (OOP, collections, exceptions, basic concurrency)
- Maven or Gradle for project management
- Basic SQL and relational database concepts
If you meet these prerequisites, you’ll be able to follow along and get a lot out of the exercises.
How to get the course and stay notified
The course is dropping soon. If you want to be the first to know when it goes live, make sure you’re subscribed to the Programming with Mosh channel and have notifications turned on. I’ve put my heart and soul into creating this course and I can’t wait to share it with you.
Final thoughts
Spring Boot is essential for modern Java development, and learning it thoroughly will pay off both in the quality of software you can build and in your career opportunities. This course is focused on real understanding and practical skills — dependency injection, Spring Data JPA, and the deeper concepts that make you a better developer. I look forward to seeing you in the course.
