Description
Master the Core Fundamentals of Spring Framework and Build Rock-Solid Java Applications

Are you ready to take your Java development skills to the next level? This comprehensive Spring Framework course will teach you everything you need to know about Spring's core concepts, from the ground up.

Why This Course?

Spring Framework is the most popular Java framework used by millions of developers worldwide. But here's the problem: most developers jump straight into Spring Boot without understanding the fundamental concepts that power it. This course fixes that by teaching you thecore principlesthat make Spring so powerful.

What Makes This Course Different?

Deep Dive Into Core Concepts: Unlike surface-level tutorials, we explore how Spring actually works under the hood. You'll understand WHY things work, not just HOW to make them work.

Theory + Practice Approach: Every concept is explained theoretically first, then immediately reinforced with hands-on coding exercises using real-world examples like coffee shop and restaurant applications.

Professional Development Setup: Learn to work with IntelliJ IDEA like a pro, including project setup, navigation, and debugging techniques.

What You'll Master:

Section 1: Foundation Concepts

Inversion of Control (IoC): Understand this fundamental design principle and its relationship with SOLID principles

Dependency Injection: Master all three types of DI with practical implementations

IntelliJ IDEA Mastery: Complete IDE setup and project structure understanding

Section 2: Spring Core Deep Dive

Spring Container: Configure applications using XML, Java Config, and component scanning

Bean Definitions: Create and manipulate bean definitions programmatically

Bean Scopes: Master Singleton, Prototype, and custom scopes with real-world scenarios

Bean Lifecycle: Control bean initialization and destruction with various callback methods

Advanced Topics:

Bean Factory Post Processors (BFPP): Build custom processors to modify bean definitions

Bean Post Processors (BPP): Create powerful interceptors using dynamic proxies and CGLIB

Spring Annotations: Master @Configuration, @ComponentScan, @Autowired, @Qualifier, and more

Aspect-Oriented Programming (AOP): Implement cross-cutting concerns with various advice types

Hands-On Learning Experience

You'll build multiple practical applications throughout the course:

Coffee shop instruction system demonstrating IoC and DI

Restaurant service application showcasing Spring Container features

Custom annotation processors for real-world scenarios

AOP implementations for logging and error handling

Students Feebdack:

Over 500 studentshave already completed my Russian-language version of this course on Stepik platform.

"I really enjoyed the course. It will be very useful for beginners. I've been working as a Java developer for 5 years and decided to dive deeper into Spring out of curiosity. I definitely don't regret taking it - I learned something new and refreshed my knowledge on familiar topics."

Who this course is for:
- ava developers with 1-3 years of experience who want to learn enterprise-level framework development and understand how Spring works internally
- Backend developers looking to master dependency injection, IoC containers, and aspect-oriented programming for building maintainable applications
- Senior developers who use Spring but want to understand the underlying mechanisms and core concepts more deeply
- Developers from other frameworks (like .NET, Python Django) who want to understand Java's premier enterprise framework
