Description
Master the Core Fundamentals of Spring Framework and Build Rock-Solid Java ApplicationsAre 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 the core principles that 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 ConceptsInversion of Control (IoC): Understand this fundamental design principle and its relationship with SOLID principlesDependency Injection: Master all three types of DI with practical implementationsIntelliJ IDEA Mastery: Complete IDE setup and project structure understandingSection 2: Spring Core Deep DiveSpring Container: Configure applications using XML, Java Config, and component scanningBean Definitions: Create and manipulate bean definitions programmaticallyBean Scopes: Master Singleton, Prototype, and custom scopes with real-world scenariosBean Lifecycle: Control bean initialization and destruction with various callback methodsAdvanced Topics:Bean Factory Post Processors (BFPP): Build custom processors to modify bean definitionsBean Post Processors (BPP): Create powerful interceptors using dynamic proxies and CGLIBSpring Annotations: Master @Configuration, @ComponentScan, @Autowired, @Qualifier, and moreAspect-Oriented Programming (AOP): Implement cross-cutting concerns with various advice typesHands-On Learning ExperienceYou'll build multiple practical applications throughout the course:Coffee shop instruction system demonstrating IoC and DIRestaurant service application showcasing Spring Container featuresCustom annotation processors for real-world scenariosAOP implementations for logging and error handlingStudents Feebdack:Over 500 students have 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
